UNI-T UDP6722 Programmable DC Power Supply 80V 20A
The UNI-T UDP6722 is a compact, high-performance programmable DC power supply that delivers up to 80 V and 20 A (400 W). It employs a 4.3 inch TFT-LCD interface to present output parameters clearly, enabling intuitive real-time monitoring and control. As a switching-mode design with full-range high resolution, it maintains low ripple and noise across its output span. Built-in protections include overvoltage (OVP), overcurrent (OCP), and overtemperature (OTP) safeguards to ensure both instrument and user safety. An integrated remote-sensing function compensates for voltage drops over lengthy cables, guaranteeing precise load-end voltages.
Advanced output sequencing is supported through list and delayer modes each accommodating up to 200 programmable steps facilitating simulations of dynamic load conditions. Waveform visualization of voltage, current, and power is displayed directly on the screen, allowing users to observe transient behaviors without external instruments. Intelligent fan regulation optimizes cooling with minimal acoustic impact.
Multiple communication interfaces (RS-232, RS-485, LAN, USB Host, USB Device) with SCPI/MODBUS protocol support enable seamless integration into automated test systems and remote operation. Housed in a lightweight chassis (214 × 88 × 393 mm, 4.65 kg), the UDP6722 is tailored for laboratory, R&D, and production environments requiring precise, flexible DC power delivery.
