UDP6900

New

The UDP6900 series are single output programmable DC power supplies. It can achieve a variety of voltage and current combination outputs under a fixed power. A single power supply can meet the test of two types of DUTs, high voltage and low current or high current and low voltage, greatly saving your cost and space. UDP6900B series has standard RS232, RS485, LAN, USB and analog interfaces, supports SCPI protocol, and is convenient for remote control, industrial PLC control and building an intelligent test platform. Widely used in various testing fields such as DC/DC power modules, battery charging and sensors.
