In addition, series operation provides a dynamic load response superior to that of parallel operation during abrupt changes in load. Therefore, we recommend operation in series for dynamic loads in order to increase power. : Output terminal : Connection Modular power supply Instruction Manual
nPlease consider the following when configuring your supply for parallel operation. Please consult us as regarding usage methods for remote sensing. Peak loads cannot be obtained. When adjusting the output voltage of modules connected in parallel, all connected modules must be adjusted. If precision adjustment is required, remove the bus bar between modules, adjust the output voltage, and reinstall the bus bar. Large differences in set output voltages will lead to large variances in load. Adjust voltages to values as close together as possible, in order to minimize load variance. nAt startup, modules connected in series or in parallel, may show stepped input and output voltage waveforms. This is due to a delay in the rise time.
Input ON AC Input voltage 2 Series operation and Parallel operation in Modular power supply
2.1 Series operation
nSeries operation is possible only between identical output modules. If series operation is specified in the part number, the supply will be shipped with a series bar installed. However, series operation is possible with modules S, T, U, Y, W, Z, 9, Q, and V, but series bar cannot be specified. nThe output current in series operation is the same as that of the individual modules that are connected. nPlease consider the following items when configuring your supply for series operation: Connect only the same type of modules in series. A total rated voltage of up to 48V can be set up for series operation. Modules in the same power supply can be set up for series or parallel operation, but not both. Please consult with us for usage other than in accordance with the above conditions. ACE Output voltage Fig. 2.1 Start-up waveform for series and parallel operation 3 Function
2.2 Parallel operation (applying module : A-K, 2A-2K)
nParallel operation is possible using modules with identical output voltage. If parallel operation is specified in the part number, the supply will be internally configured accordingly, and shipped with the appropriate bus bar in place. Parallel operation cannot be set up once the unit has been shipped.
nOutput current in parallel operation. Current ratings for output modules connected in parallel are derated by 10%. Ex.: AC4-HHECB-08 Parallel code 08 means slots 4 and 5 are connected in parallel. The output module for slots 4 and 5 is "H". Therefore, the current is as shown below: Current = (6.5A+6.5A) 0.9=11.7 A 3.1 Input voltage range
nThe input voltage range is from 85 VAC to 264 VAC, or 120 VDC to 350 VDC. Compliance with safety standards (agency approval) is limited to use with AC input voltage only.
nBe aware that use of voltages other than those listed above may re- sult in the unit not operating according to specifications, or may cause damage. Avoid square waveform input voltage, commonly used in UPS units and inverters. 3.2 Inrush current limiting
nInrush current limiting is built-in. nIf a switch is being used for input, ensure that it is rated to handle the input inrush current. When turning the power OFF and then ON again within a short period of time, the inrush current limiting may be disabled, therefore, ensure sufficient time elapses before restarting. nInrush current limiting uses a thyristor, therefore primary inrush current and secondary inrush current are generated. If power is turned ON and OFF repeatedly, failure may result. Please allow enough time between power ON and OFF. C-17 Modular power supply Instruction Manual
3.6 Output voltage adjustment
nOutput voltage can be adjusted by turning the internal potentiom- 3.3 Overcurrent protection
nOvercurrent protection is built in (activated at 105% of the rated
current, or for operation with peak current, at 101% of the peak current); however avoid short circuits or overcurrent.The unit automatically recovers when the cause of the short or overcurrent is cleared. eter.
nRefer to specifications for adjustment ranges. Please consult with us regarding operation outside the specified ranges. For modules Y, W, Z, 9, and Q, turning the internal potentiometer clockwise increases the positive voltage and decreases the negative voltage simultaneously. nWhen the output voltage drops as a result of the overcurrent circuit being activated, the average output current is reduced by intermittent operation of the power supply (intermittent overcurrent mode). nAuxiliary power (AUX) Output that supplies power to the RC terminal of output modules. AUX power is designed to be used for control of the remote 3.7 Remote sensing (applying module : A-K, 2A-2K)
nEach output module incorporates remote sensing functions. nIf remote sensing is not used, then please short +S and +M, and -S and -M at the CN2 output module. Fig. 3.1 shows wiring for when remote sensing is not used. The unit is shipped with harnesses for when remote sensing is not used.
Output module OUT +V -V +M +S -S -M Load ACE ON/OFF function. nPeak current protection (applicable modules: 2E-2K) Peak current protection is built in (refer to Output module specifications 1 for peak current usage methods). Peak current protection operates independently for each output module. Its activation will not halt the entire power supply. Shut off input AC voltage, wait for at least 2-3 minutes, and recycle to recover output voltage( ). The recovery time varies depending on input voltages and load status during operation. CN2 Short at connector 3.4 Thermal protection
nThermal protection is built in. If either of the following takes place, Fig. 3.1 When the remote sensing function is not used
nWiring method with remote sensing is shown in Fig.3.2. nPlease consider the following when using remote sensing: Be sure connections are made properly. If the load wire is not connected correctly, a load current may flow through the sensing wire, which could damage circuitry inside the power supply. Wire of an appropriate type and gauge should be used to connect the power supply to the load. Line drop should be less than 0.3V. When using the remote sensing function, oscillation in the power supply output voltage, or significant variations in output voltages can be generated by wiring or load impedance. The following are ways to remedy instability in output voltage. Remove remote sensing from the negative side, and short -S and -M at the CN2 on each output module. If oscillation occurs, connect C0, C1, and R1. Please consult us for details. nEnsure that current is not drawn from the CN2 +M or -M terminals. the thermal protection may be activated, shutting off the output:
The current or temperature is continuously in excess of the derating curve. The fan has stopped or the airflow from the fan is reduced by an obstruction. If the thermal protection is activated, shut off input voltage, remove the cause of the overheating, wait for the unit to cool down, and recycle to recover output voltage. 3.5 Overvoltage protection
nOvervoltage protection operates independently for each output module. Its activation will not halt the entire power supply. Overvoltage protection is built in. When the overvoltage protection is activated, shut off input, wait for at least 1-2 minutes, and recycle to recover output voltage. The recovery time varies depending on input voltage, etc. When testing the power supply for overvoltage performance or applying voltage from the load circuit, please note that components inside the power supply might fail if the voltage applied exceeds the rated output voltage.

nEach output module incorporates remote ON/OFF functions. nWhen performing incoming inspections, ensure that the applied voltage is increased gradually. Additionally, when turning off power to the unit, use a dial to gradually reduce the voltage. Do not use a voltage tester in conjunction with a timer. Doing so may generate voltage several times higher than the applied voltage. Output voltage ON/OFF can be controlled by applying a voltage to CN2 at each output module.
nDedicated auxiliary power (AUX) for remote ON/OFF. Auxiliary power (AUX) is built-in for control of remote ON/OFF. Auxiliary power (AUX) is isolated from input, output, and FG. Remote ON/OFF connection methods with AUX are shown in Fig. 3.3. nRemote ON/OFF control logic. The output stops when voltage (4.5 - 12.5V) is applied to RC+. Reverse logic option (-R) also available.Refer to section 5. Option. The built-in fan does not stop even if the output is turned OFF using remote ON/OFF. If the output has been turned OFF using remote ON/OFF, the LV alarm signal will be generated (except modules, S, T, and U). This function operates on each output module independently. nRemote ON/OFF circuits operate independently on each output module; therefore it is possible to use remote ON/OFF on individual output modules. Please be aware that this cannot turn off all outputs together. If turning off all output modules together is a requirement, we recommend use of the remote ON/OFF circuits in series or parallel. nThe remote ON/OFF circuit (RC+, RC-) is isolated from input, output, and FG.

nThe following two types of alarm function are built in. Refer to Table 3.2 for details. PR: abnormal input voltage, fan alarm LV : abnormal output module voltage (except modules S, T, and U). Table 3.2 Explanation of alarms
Alarm Output of alarm PR When input voltage is abnormal (low input voltage) or the fan stops, the alarm signal is generated from CN1. Open collector method Good : Low (0-0.8V, 1-20mA) Fail :35V max LV When rated output voltage decreases or stops, the alarm signal is generated from CN2. Note : In the event of overcurrent output (intermittent current), operation of the alarm will become inconsistent. The LV alarm is not isolated from output. Therefore, make sure all connections are correct when the power supply is used to supply negative voltage or is operated in series. (Refer to Fig. 3.5).

nThe ACE series comprises power supplies consisting of a combination of output modules. Make sure each output module is used within specifications, and that the total output power of all modules is equal to, or less than the rated total output power. nThe derating curve for the ambient temperature (inlet temperature for cooling) of output modules is shown in Fig. 4.6. nOperation within the hatched area will result in different ripple and ripple noise specifications. Fig. 4.1 Air flow nIf the unit is used in a dusty environment, an air filter should be used so the cooling efficiency of the fan is not reduced. nIf the fan stops, the thermal protection may be activated, shutting down the output. Life expectancy of the fan varies depending on usage conditions; therefore regular inspections of the fan are required for increased reliability. Should the fan become nonoperational over the course of time, it can be replaced. Refer to the optional parts section of this catalog. C-20 Modular power supply Instruction Manual
