1 Description
The EM2100 is a 120V 15 amp three-bank AC power sequencer incorporating SurgeX
®
power
conditioning and surge protection. The surge protection is rated A-1-1, the highest standard of the Federal
Commercial Item Description for Endurance. A total of fourteen 120V receptacles are provided on the
rear panel, two of which are always on, with the remaining twelve configured as three sequenced banks of
four receptacles, labeled A, B and C.
SurgeX ICE Inrush Current Elimination circuitry is incorporated into the EM2100. This eliminates
problems associated with inrush currents from large loads such as amplifiers. With SurgeX ICE it is
not necessary to take inrush currents into account when designing the AC power for a system, and special
time-delay circuit breakers are not required: you only need to ensure that the steady-state currents of all
products plugged into the EM2100 are within the 15 Amp rating of the product and within the rating of
the AC wiring.
The front panel houses a three-line display which provides status information in normal use and allows
interaction with menu items during programming. Also on the front panel are two screwdriver-accessible
rotary encoders which are used to step through and select from a menu of items which determine the
operation of the unit. The black push button, when pressed, causes the unit to power up or power down.
This button can be disabled if not required. The blue LED above the button indicates the status of the
unit. When the LED is off the unit is fully powered down; when it is on the unit is fully powered up;
when it is flashing the unit is in the process of powering up or down.
A built-in AC voltmeter indicates the line voltage on the third line of the display. The internal voltmeter
is a peak reading type which was chosen because most electronic equipment incorporates a power
supply that charges mostly during the AC peaks. Monitoring the peak of the AC provides a more useful
indication of the actual voltage available to the electronic equipment plugged into the EM2100.
The EM2100 is microprocessor controlled and designed to be versatile and expandable. Two or more
EM2100s can be connected together to provide control and power conditioning for larger systems.
The EM2100 can also control other Empower products with its auxiliary relay contacts to provide for
expandability. All options are set via the front panel and all connections are made at the rear panel.
An optional password of up to six letters can be entered preventing unauthorized access to set-up
information. All set-up information is stored in a non-volatile memory.
A plug-in Phoenix terminal block on the rear panel accommodates the remote control connections and
also the low-voltage outputs. There are three inputs which control sequencing; one programmable 12V
dc output; and one programmable auxiliary relay providing normally-open contacts. The inputs can be
controlled by an applied DC voltage from 5V to 30V, by a contact closure, or by different types of switch;
the input selection being made during programming. The inputs and 12V output are designed to withstand
incorrect connections including polarity reversal and shorts. 4

3 Installation
The Empower EM2100 is designed to be either modular or installed in a 19 inch equipment rack using the
optional rack ears. To convert the EM2100 for rack mounting, remove the four screws in the corners of the
front panel, discard the side bezels, then attach the rack ears using the same four screws.
Connect power to the unit by plugging the cord into a 120V ac, 15 amp receptacle.
3.1 120 Volt Connections
The EM2100 has a total of 14 receptacles: three sequenced banks of four, and two always on. Each
receptacle is rated for a maximum load of 15 amps but the total load of the EM2100 must not exceed 15
amps. Plug the equipment cords into the receptacle banks as needed to turn on equipment in the required
sequence. The always on receptacles provide power as long as power is supplied to the EM2100. Bank
