Overview

The General Electric Voltage Conditioner Assembly
is used to provide voltage-sensing signals to
Spectra
microEntelliGuard
Units via the Distribution Cable System.

The assembly has the maximum capacity to provide
voltage signals to a Distribution Cable System
consisting of 20 Spectra
Breakers with microEntelliGuard
PM/Plus Trip Units with a maximum system cable
length of 40 feet.

The Voltage Conditioner Assembly requires a power
supply source voltage of +24Vdc to operate properly.
The Power Supply Assembly (catalog number SPSAA)
or Power Supply Plate (catalog number SPSAI20,
SPSA208, SPSA240, SPSA480 or SPSA600) can provide
this required input. The unit also requires 120Vac @60
Hz voltage inputs from the secondary of three 1-VA
high accuracy potential transformers (not included).
The primary side of each potential transformer must
be fused with 2-amp class CC fuses (not included). The
Voltage Conditioner Assembly is designed to operate in
temperatures between 0°C and 70°C.
