UNI-T UTP3305C — a 315 W programmable linear DC power supply from the UTP3300C series, with two independent 0–30 V / 0–5 A channels plus a fixed 5 V / 3 A logic supply. Linear regulation holds ripple to ≤2 mVrms, so it suits sensitive analogue and RF work where switching noise is unacceptable. Series and parallel modes, five memory groups, power-off memory and USB / RS-232 remote control make it a strong fit for R&D, production test and teaching labs. Genuine UNI-T product supplied by Digilog.pk with manual and warranty.
Key Features
- Three outputs: CH1 and CH2 each 0–30 V / 0–5 A, plus a fixed 5 V / 3 A CH3 — 315 W total
- Linear topology for low ripple: ≤2 mVrms voltage, ≤3 mArms current (20 Hz – 20 MHz)
- Series and parallel operation for higher voltage or current
- High-precision 4-digit voltage and current display, 10 mV / 1 mA resolution
- One-click data recall of up to 5 groups; power-off memory; keyboard lock
- Over-voltage, over-current and over-temperature protection; software calibration
- USB Device and RS-232 interfaces (optional LAN)
