UNI-T UDP6721 Fuente de alimentación de laboratorio, 0-72 V DC, 0-1 A, 72 W, monocanal, programable

The UNI-T UDP6721 stands out as a precision single-channel DC laboratory power supply, delivering a wide 0–72 V output range with 1 mV voltage and 0.1 mA current resolution. Unlike many bench supplies in its class, it combines a 2.8-inch TFT LCD display, USB/RS232/LAN connectivity, and 10 memory presets — making it a flexible tool for electronics development, testing, and repair.

Highlights

• Single output channel: 0–72 V DC, 0–1 A, up to 72 W
• High resolution: 1 mV / 0.1 mA setting and readback
• Low ripple & noise: ≤1 mVrms (voltage), ≤1 mArms (current)
• 2.8-inch TFT LCD for clear, real-time monitoring
• Communication interfaces: USB Device, RS232, LAN
• Protection: OVP, OCP, OTP
• 10 memory presets for quick recall of common settings
• Excellent regulation: load/line ≤0.01% + 2 mV / 2 mA

In daily use

This power supply is ideal for benchtop tasks requiring stable and precise DC output — from powering prototypes to testing components. The fast transient response (<50 µs) ensures clean power delivery even under dynamic loads. The intuitive interface and preset storage streamline repetitive work, while remote control via USB, RS232, or LAN enables automated testing and data logging.
