UNI-T UDP4303S 4-Channel Programmable Linear DC Power Supply 297W

Features:

• Four Independent Output Channels: Provides four isolated DC output channels for powering and testing multiple circuits simultaneously.

• High Total Output Power: Delivers up to 297W of combined output power for laboratory testing, electronics development, and production applications.

• Multiple Voltage and Current Ranges: Includes two 32V/3A channels, one 15V/3A channel, and one high-current 6V/10A channel.

• Programmable Linear Regulation: Uses linear power-supply technology to provide stable output with low ripple and noise.

• High-Resolution Control: Supports 1mV voltage resolution and microamp-level current measurement for detailed testing of sensitive electronic circuits.

• Series and Parallel Operation: Channels 1 and 2 support internal series and parallel connections for flexible output configurations.

• Remote Voltage Sensing: All four channels support 2-wire and 4-wire sensing to compensate for voltage drops in test leads.

• Waveform Monitoring: Displays voltage, current, and power waveforms across the four channels, with a current sampling rate of up to 8kSa/s.

• Programmable Sequences: Supports list and delay functions with up to 512 output steps and a minimum programming time resolution of 1ms.

• Computer-Controlled Operation: Supports remote control through LAN, USB, RS-232, and digital I/O interfaces, with SCPI protocol support.

• Built-In Protection: Includes overvoltage protection and reverse-connection protection, along with monitoring functions for safer testing.
