III. SPECIFICATIONS
MODEL 843 POWER SUPPLY MODULE
DESCRIPTION:
Both the input and output connections are made with a PC edge connector at the rear of the module.
A fully shielded, toroidal power transformer allows the PS module to operate adjacent to a high-gain amplifier module
without inducing 60Hz pick-up noise. Rectifiers and electrolytic capacitors complete the circuit which provides the +,-
24VDC (nominal), unregulated output voltages. These voltages are routed through the PC connector to each amplifier
module, where they are regulated as needed.
MECHANICAL:
The power supply module is 7"H x 2.8"W x 12"D and weighs 4.5 lbs.
ELECTRICAL:
INPUT:
115V +,-10%, 50/60 Hz @ 0.8A Max.
OUTPUT:
Eight unregulated, transformer isolated DC outputs, as follows:
1@ +24VDC at nominal line and full load; 1.2A MAX.
1@ -24VDC at nominal line and full load; 0.6A MAX.
7@ +24VDC @ 0.08A@ (.56A total)
Ripple: 1.5V PK/PK Max. per output
CONTROLS:
Power "ON" switch and Indicator lamp.
