14.1. Electrical Specifications

Externally 3 wires (Hot, Neutral, Ground) conduit route through either

side (left / right) access panel orifice (Hot, Neutral) go to two in-line

breakers that connect to VAC In (range 85-265) power supply,

Outputting 28 Volt DC with 600 Watts capability providing power to all

the power amplifiers and in part regulated to 48 and 12 Volts for

discrete devices.

The Hot and Neutral wires connect internally to 2 in-line 1 pole 10 amp

circuit breaker (FS-Pn 760-0025 see Figure 23), mfr’s pn 1BU10 by

Altech Corp., that provides RFN protection.

Incoming external ground (GND) wire connects inside to a chassis

ground lug.

In the event primary power supply shuts off, as backup, design incorporates a second parallel

equivalent power supply so that the equipment will continue to operate without interruption.

Both breakers are DIN Rail mounted and

have the UL508 safety standard.

For recommended terminal connection to

the circuit breaker see Figure 24.
