UDP4303S Overview
The UDP4303S is a high-precision programmable linear DC power supply featuring four independent output channels. It is designed for ease of use with a clear, bright display screen and intuitive controls, offering six interface display styles for better viewing of measurement results.
One of its standout features is the one-key setting for series and parallel connections between CH1 and CH2 of the main channel, eliminating the need for external connections and simplifying testing. The tracking function allows changes in one channel's settings to automatically adjust the other channel accordingly.
With a current resolution in the µA class, the UDP4303S is 1000 times more capable than previous generation power supplies. Advanced functions such as List, Delayer, Monitor, Trigger, and Recorder help automate tests, monitor and protect intelligently, and record essential data.
The power supply boasts a rich remote control interface, including standard RS232, Ethernet, Digital I/O, and USB interfaces, enabling remote control via Ethernet, RS232, or USB with host computer software. It offers a programming time resolution of up to 1ms and can produce exact arbitrary waveform outputs. The device accurately captures transient changes in load current with a sample rate of up to 8kSa/s, 2000 times higher than previous models.
Adjustable overcurrent protection parameters help avoid false triggers during events like load starting current, and the response time is impressively fast at less than 3ms. The UDP4303S also features four channels of full remote compensation, automatic line loss compensation, reverse protection, and overvoltage protection. Intelligent fan speed control effectively reduces noise during operation.
For storage and presets, the device can save 10 status files, 10 list files, and 10 delayer files locally, with five groups of often-used settings available in presets. A USB flash drive can be used to save and recall additional settings files. The keyboard lock function prevents misoperation, ensuring reliable and secure usage.
