UNI-T UDP4303S Programmable Linear DC Power Supply 4Ch 297W 32V/10A
The UNI-T UDP4303S Programmable Linear DC Power Supply is a precision bench power supply designed for electronics development, circuit testing, laboratory measurements, and automated production testing. Its four electrically isolated output channels provide flexible voltage and current combinations, allowing engineers to power multiple circuits or devices simultaneously. With a total rated output power of 297W, the UDP4303S combines low output ripple, accurate voltage and current control, and extensive programming functions in a compact bench instrument.
Features:
- Four electrically isolated and independently controlled output channels.
- Total rated output power of 297W.
- Two 0–32V/3A outputs, one 0–15V/3A output, and one 0–6V/10A output.
- Internal series and parallel operation for Channels 1 and 2.
- Remote sensing support on all four channels for voltage-drop compensation.
- Voltage programming resolution of 1mV and current programming resolution of 0.1mA.
- Low output ripple and noise of less than 350μVrms and 2mVpp under specified conditions.
- Fast transient response of less than 50μs under the manufacturer’s specified test conditions.
- 4.3-inch TFT-LCD with 480×272 resolution.
- Programmable list output for creating timed voltage and current sequences.
- Waveform display for observing output behavior.
