Description
WHAT IS IT
A compact mains-powered single-output DC bench power supply with simultaneous voltage, current and power display on a four-digit readout. Features both CV (constant voltage) and CC (constant current) modes with a dedicated output ON/OFF switch and a built-in USB quick-charge port.
FOR MAINS USE — Fused IEC 115–230V wide voltage input
WHAT IS IT USED FOR
Ideal as a beginner’s small, simple, general-purpose bench power supply for electronics testing, prototyping, charging, and powering circuits where you need precise, adjustable voltage and current limiting. The CC mode makes it useful for battery charging and protecting sensitive loads.
FEATURES
- Simultaneous display of voltage, current and power — no switching between screens
- Independent ON/OFF output switch (green = on, red = off) — change settings without powering the load
- Remembers your last voltage and current settings after power-off
- CV (constant voltage) and CC (constant current) modes with indicator LEDs
- Rotary knob lock function to prevent accidental adjustment
- Built-in QC 18W USB quick-charge output (5V/3A, 9V/2A, 12V/1.5A)
- Active cooling fan on the rear panel, off in zero or low load
- Comes with instructions sheet, power leads and UK mains cable
HOW DO I SET IT UP?
- With the rear power switch off, connect your mains lead.
- Power on.
- Short-click the Voltage knob to select the units to change – hundredths, tenths, units or tens.
- Rotate the voltage knob – changes will carry up
- Leave for a second to set the new voltage
- Repeat for current
- Connect your load to the positive and negative output terminals.
- Press the front ON/OFF button to enable output — the button changes from red to green when power active.
