1 Safety and Recommended Practices
1.1 General Safety Instructions
This power supply is a switch mode power supply for use in applications meeting a Pollution Degree
2 environment. A suitable mechanical and fire enclosure must be provided by the end use equip-
ment for shock hazard protection, fire protection and protection from hazardous energy levels.
READ SAFETY INSTRUCTIONS carefully before working on the unit.
HIGH VOLTAGE WARNING: Dangerous voltages are present within the power supply.
NO USER SERVICEABLE PARTS INSIDE.
1. Do not install, test or operate this product near water, and do not spill any liquid on it.
2. Do not operate this product unless it is in a secure position.
3. This product must be installed and put into service by authorized competent personnel only
who are fully conversant with the hazards of AC line operated equipment and with the
particular dangers associated with switch mode power supplies.
4. This product is designed for use within other equipment or enclosures which restrict access to
authorized competent personnel only and must not be user accessible.
5. This product must be reliably earthed and professionally installed in accordance with the
prevailing electrical wiring regulations and safety standards. The product's PE connection is via
the tapped standoff and screw on the front panel marked with IEC 60417-1 Symbol 5019.
6. The case is connected to the products PE connection with screws. Therefore, screws at the case
must not be removed or loosened.
7. The output power taken from the power supply must not exceed the rating stated on the power
supply label.
8. Openings in the product case are designed for ventilation and must not be obstructed when
the product is installed and/or operated.
9. Never push objects of any kind into the product through openings in its case as this could
result in electric shock or fire hazard.
10. Use copper stranded wire only, 12 to 14 AWG rated at 105°C for the AC input. All strands
must be secured in the terminal block to avoid potential danger of short circuit.
11. Properly torque AC input terminals to 9 in-lb.
12. An internal fuse protects the unit and must not be replaced by the user. In case of internal
defect, the unit must be returned to the manufacturer.
13. The output of this power supply is hazardous and must not be user accessible in the end use
equipment. The (+) or (-) output can be earthed. Use wire rated at 105°C
and
sized for 150%
of the rated load.
14. The unit contains components that require special disposal. Make sure that the unit is
properly disposed of at the end of its service life.
1.2 Safety Agency Approvals
Regulatory agency compliance applies only for operating frequencies between 47- 63Hz.

** Output current and power, as measured at output terminals, must be less than or equal to
quoted maximum values for a given ambient temperature.
*** Regulatory agency compliance applies only for operating frequencies between 47-63Hz.
No safety agency approvals for 100-380 VDC operation. Minimum turn-ON voltage for
DC Input is 110 VDC, unit will operate as low as 65 VDC after Power-up. Lambda doesnt
recommend operation below 100 VDC for more than one minute, or damage may occur. Revision H : January 2008

Series Operation
Yes (see Fig. 7)
Parallel Operation
Two or more identical units (see Fig. 6). (Use of D. con. terminal 5 will
(with current sharing)
provide current sharing to within 3% nominal of rated 40°C current.)
DC Output Controls and Indicators
Table 6
Output Voltage Adjust
Screwdriver adjustment over entire range. Output voltage range is from
18-29.4V. (Multi-turn potentiometer accessible from terminal end of chassis.)
Overvoltage Protection Adjust
Screwdriver adjustment over entire range. Overvoltage trip range is from
20-34V. Factory setpoint is 31.0V. (Multi-turn potentiometer accessible
from terminal end of chassis.)
Output Good Indicator
Green colored LED illuminates when output is within specified operating range
Fault Indicator
Red colored LED illuminates if overvoltage, overtemperature, or overcurrent
shutdown occurs. The LED is also illuminated if the output is less than approximately
95% of its adjusted output or if the output is inhibited (stand-by mode).
