Overview

62000H Series DC Power Supply can be controlled remotely via USB, GPIB, Ethernet,
RS-232 or RS-485 port.
The USB interface supports USB 2.0/USB 1.1. GPIB interface is an 8-bit parallel data bus
that synchronizes with the host bus commands. Ethernet interface is used in local area
network for data transmission. RS-232C is a serial bus with less powerful functions; however,
users can do remote control easily via simple programming.
