As electrical equipment safety standards continue to evolve, the demand for coordinated verification of power supply stability and grounding reliability in test systems has increased significantly. UNI-T introduces two professional instruments—the UDP5000 Series Wide-Range Programmable Switching DC Power Supply and the UT5140 AC/DC Ground Bond Tester. By combining precise power control with reliable safety monitoring, these instruments effectively support applications such as new energy battery testing, semiconductor aging tests, and power system safety inspections, providing a more comprehensive test and verification solution for complex electrical environments.

Continuous Power, Uninterrupted Performance

UDP5000 Series Wide-Range Programmable Switching DC Power Supply

The UDP5000 Series Wide-Range Programmable Switching DC Power Supply supports up to 4 units in parallel and 2 units in series, with maximum expandable power, voltage, and current of 4800W, 500V, and 480A, respectively. It offers selectable CC/CV modes, adjustable internal resistance from 0.000Ω to 31.250Ω, and adjustable voltage and current slew rates of 0.01–500.00V/s and 0.01–72.00A/s, respectively. With a power ratio of up to 4.0, it supports List and Delay functions and enables automated system integration through SCPI commands and a WebServer interface. Its redundant architecture and multi-level protection design support 24/7 full-load operation and up to ten years of maintenance-free service, delivering a highly reliable, stable, safe, and compliant power solution for laboratories and production lines.
