UNI-T UDP4303S Programmable DC Power Supply

The UNI-T UDP4303S DC Power Supply is designed for engineers and technicians who need reliable, flexible output options in one compact unit. It features four independent channels—two 32 V/3 A, one 15 V/3 A, and one 6 V/10 A—with extremely low ripple noise output and excellent load regulation. Each channel is isolated and supports remote sensing, ensuring accurate voltage delivery at the point of load. Channels 1 and 2 can be internally linked in series or parallel, offering even more flexibility for varied test setups.

Equipped with a 4.3" TFT LCD, the UDP4303S offers an intuitive interface for accessing a suite of powerful functions—list/delay, monitoring, waveform display, and more. Communication options include RS232 with SCPI support, Ethernet, and multiple digital I/Os, allowing for seamless remote control and integration into automated test systems. It’s a robust solution for production lines, R&D labs, and education settings.

Key Features:

• High Resolution Output: Current resolution down to 1µA with small current mode available on all four channels for precise low-current measurements.
• Advanced Waveform Analysis: 8 kSa/s high-speed current sampling accurately captures and displays transient changes across all channels.
• 1 ms Programming Time Resolution: This technology enables more refined output control for generating complex, user-defined waveforms—100x the resolution of previous models.
• Clear Multi-Style Display: 4.3" LCD screen with six different display interfaces for easy visualisation of measurement data.
  
• Comprehensive Test Functions: Features List, Delayer, Monitor, Trigger, and Recorder functions to support automated testing and intelligent monitoring.
  
• Flexible Output Configurations: Channels 1 and 2 support easy internal series and parallel connection via the menu for expanded output options.
  
• Fully Isolated Channels: Each of the four channels is fully isolated to ensure safety, eliminate crosstalk, and enhance reliability.
  
• Remote Compensation on All Channels: Supports 4-wire sensing, reverse connection protection, and overvoltage protection to maintain measurement accuracy and system safety.
• Channel Tracking Function: Allows channel 2 to follow changes made to channel 1, simplifying dual output setups and adjustments.
