The UTP3300 Series is three-channel linear DC power supplies of adjustable dual channel and fixed single-channel output, featuring tracking, constant voltage/current, series/ parallel output, temperature controlled cooling fan.
The UNI-T UTP3305 is a professional three-channel linear DC power supply delivering precise, low-noise power for electronics development, testing, and repair. With dual independently adjustable channels providing 0-32V at 0-5A and a fixed 5V/3A output, this 335W power supply delivers the stable, clean power essential for sensitive electronic circuits. Featuring ultra-low ripple noise (≤1mVrms for constant voltage, ≤3mArms for constant current), exceptional load regulation, and automatic constant voltage/constant current mode switching, the UTP3305 provides the precision and reliability needed by electronics engineers, technicians, educational laboratories, and repair professionals working with analog circuits, digital systems, embedded development, and precision instrumentation.
The UTP3305 utilizes linear regulation technology to deliver exceptionally clean, stable power that is essential for sensitive electronic applications. Unlike switching power supplies that introduce high-frequency noise and ripple, the UTP3305's linear design provides pure DC power with minimal interference. With ripple and noise specifications of just 1mVrms in constant voltage mode and 3mArms in constant current mode, this power supply ensures that your measurements, test results, and circuit behavior remain unaffected by power supply artifacts.
The exceptional load regulation performance (CV≤1x10-4+3mV for voltage, CC≤2x10-4+3mA for current) means the output remains stable regardless of load changes, providing consistent power whether your circuit draws minimal current or approaches the full 5A rating. This stability is critical for precision measurements, audio circuit development, and any application where power supply variations could affect circuit performance or introduce measurement errors.
