6. Theory of Operation
6.1 Overview
The 62000H Series DC Power Supply with Solar Array Simulation has a total of 18 circuit
boards in it: A, C, D, E, F, G, H, I, K, L, NO, R, S, U, Y, YE, YG, and Z.
 A board is the auxiliary power.
 C board is the output stage control circuits.
 D board is the main digital control board.
 E board is the EMI filter.
 F board is the input stage primary side.
 G board is the GPIB & Ethernet control board.
 H board is the high voltage input rectifier.
 I board is the adapter for System Bus and USB.
 K board has 24 (4*6) keys and an LED.
 L board is the low voltage input rectifier.
 NO board is the output noise board.
 O board is the output stage secondary side.
 R board is the adapter for Remote sense and current sharing.
 S board is the output stage secondary side snubber circuits.
 U board provides serial/parallel communication for System Bus and external
RS232/RS485 and USB interfaces.
 Y board is the converter for Ethernet and GPIB.
 YE board is the Ethernet external board (option.)
 YG board is the GPIB external board (option.)
 Z board is the fan control circuits.
