2. Quick Guide
This chapter briefly introduces the front panel, rear panel, keyboard function and LCD display
function of UDP6900 series power supply. To ensure that user can quickly understand the
appearance, structure and key function of the power supply before operating the power supply,
it can help you better use this series of power supply.
2.1 Product Introduction
UDP6900 series is single output programmable DC power supply. This series can realize all sorts of combined
output of voltage and current in rated power. A single power supply can meet the two kinds of objects to be
tested, high voltage and low current or high current and low voltage test, which greatly saves your cost and
space. Take UDP6942B (60V/15A/360W) as an example, it can realize various combination of 60V/6A/360W,
40V/9A/360W and 24V/15A/360W.
UDP6900 series has a built-in interface of RS232, RS485, USB and analog quantity. It supports SCPI protocol
for remote control, PLC control and setting up an intelligent test platform. It widely used in DC-DC power
module, battery charging and sensor and other testing fields.
