1-10. DESCRIPTION OF ELECTRONIC STATION (cont)
f. DC POWER SUPPLY ASSEMBLY 1A4
(1) The dc power supply assembly provides fixed voltage outputs to the electro-
optical test bench set.
It consists of a chassis assembly, four power supplies 1A4PS1
thru 1A4PS4 (Kepco Models BKF5-11, two each BKF15-6, and BKF28-4), four capacitor
assemblies 1A4C1 thru 1A4C4, three 16-contact terminal boards 1A4TB1 thru 1A4TB3, and
Three electrical cable assemblies enter the rear of the chassis and
terminate at the terminal boards.
A ground lead is installed on the base of the dc
power supply assembly and connected to a ground lead which is connected to the
(2) The power supplies are mounted to the base of the assembly. They are voltage
regulated dc sources and each contains circuits for overvoltage and fused circuits for
short circuit protection.
A seven-contact terminal board is mounted on top of each
Wiring and one electrolytic current aiding capacitor assembly are
connected to the terminal board.
Power Supply Characteristics:
*Based on maximum voltage input of 125 vac.
Weight 100 lb (approximate)
115v + 10v, 60 Hz
