Overview

The General Electric Power Supply Plate is used to provide +24Vdc Control Power to Spectra Case Circuit Breakers with microEntelliGuard MicroVersaTrip Cable System. The Power Supply Plate also provides power to the Voltage Conditioner Assembly or Voltage Conditioner Plate (Spectra Breakers with microEntelliGuard PM Trip Units require connection to a Voltage Conditioner Assembly or Voltage Conditioner Plate to function properly). The Power Supply Plate includes the Power Supply Assembly (catalog number SPSAA) as an

integral component and also includes fuse protection for the AC source input terminals.

The Power Supply Plate is rated 24 watts (+24Vdc @

1.0 Amp) and has the maximum capacity to power a Distribution Cable System consisting of either a Voltage Conditioner Assembly or a Voltage Conditioner Plate AND 20 Spectra with microEntelliGuard Trip Units with a maximum system cable length of 40 feet. The Power Supply Plate is designed to operate in temperatures between O°C and 70°C.

Figure 1 shows how the Power Supply Plate is used in a typical MicroVersaTrip® PM system. Figure 2 shows how the Power Supply Plate is used in a typical MicroVersaTrip

Plus system. The microEntelliGuard

Trip Unit can

be used with either conﬁguration, i.e. Figure 1 or Figure 2. The connection diagram shown in Figure 2 applies to

The Power Supply Plate is available in ﬁve ratings. Table 1 contains a listing of all GE Power Supply Plates. All units are rated 60 Hz. Supplemental 24Vdc input terminals are provided for systems that have access to an external +24Vdc power supply. If this supplemental input is connected, the assembly will continue to pass the control power to breakers and accessories connected to the Distribution Cable System if the primary AC power is lost or drops below the minimum requirement. This backup input must meet ANSI C37.90.1 for oscillatory and fast transient surges (the Power Supply Plate provides this protection for the primary AC input). Additional 24Vdc output connections are supplied for applications where +24Vdc control power is required independent of the Distribution Cable System (i.e., feeding an Air Circuit Breaker or

Insulated Case Breaker with microVersaTrip

EntelliGuard

TU Trip Unit).

The Power Supply Plate contains six connection points. Refer to Figures 4 and 5 for connection details and location information. The following is a detailed list of the Power Supply Plate connection points:

• “To Distribution Cable” – 12-pin plug connector that mates with the 12-pin

receptacle of a Distribution Cable Harness (catalog number SDCHA11 , SDCHA30 or SDCHA60).

• “To Voltage Conditioner” – 12-pin plug connector that mates with the 12-

pin receptacle of a Distribution Cable Harness (catalog number SDCHA11, SDCHA30 or SDCHA60).

For Spectra with microEntelliGuard

RMS Molded-Case Circuit Breakers

, MicroVersaTrip® PM Trip Units, the other end of the harness MUST connect to either a Voltage Conditioner Assembly (catalog number SVCAA) or a Voltage Conditioner Plate (catalog number SVCA120Y, SVCA208Y, SVCA240D, SVCA277Y, SVCA480Y, SVCA480D or SVCA600D) for the breaker to function properly.

• “Input Voltage” – Two-screw terminals on the fuse block for

connection of the primary AC source.

• “Input” – Three-screw terminal block on the Power Supply

Assembly. Use one-terminal screw for connection of the ground (the other two-terminal screws are factory wired to the load side of the fuse block).

• “Output to 24Vdc” – Two-screw terminal block for optional control power

output (in lieu of using the Distribution Cable System).

• “Supplemental Input 24Vdc” – Two-screw terminal block for connection of an

external +24Vdc power supply.

By plugging the Power Supply Plate into the Distribution Cable System, you create system wide signals that are available to all breakers connected to the system; a list of those functions appears in Table 3.
