Wattage

Requirements

The NIM must be supplied 13 W of power. In addition each BOS module on your

island must be supplied 7 W of power. When selecting your power sources keep in

mind these power requirements. For instance, if you have a NIM and a single BOS

on your island and you are using a single supply, add their power requirements

together to come up with the total power requirement for the single supply.

Supplies

We recommend the Phaseo ABL7 family of power supplies. Phaseo power supplies

are distributed in the United States by Square D. Here are three possible power

supply solutions for an island with 24 VDC modules:

1 supply for 3 connections (logic power, actuator power and sensor power):

ABL7 RP 2410 (10 A maximum)

2 supplies for 3 connections (1 for logic power, 1 for actuator and sensor power

For Logic power: ABL7 RP 2402 or ABL RE 2402

For the 24 VDC PDM: ABL7 RP 2410 (10 A maximum)

3 supplies for 3 connections (1 for logic power, 1 for actuator power, 1 for sensor

power)

For logic power: ABL7 RP 2402 or ABL7 RE 2402

For the 24 VDC PDM sensor: ABL7 RP 2405 or ABL7 RE 2405 (5 A maximum)

For the 24 VDC PDM actuator: ABL RP 2410 (10 A maximum)

For more information on recommended supplies contact your Schneider Electric

representative.

Note: If the 24 VDC source power supply also supplies field voltage to a (PDM),

you must add the field load to your wattage calculation. For 24 VDC loads, the

calculation is simply amps x volts = watts.
