Overview

The 62000H Series DC Power Supply with Solar Array Simulation has A, C, D, E, F, G, H, I,
K, L, NO, R, S, U, Y, YE, YG, Z a total of 18 circuit boards (62150H for example) as listed
below.

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 of 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 of 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 of 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.
