About This Instrument
The Vartech 3005 B is a high-quality single-output transformer-based linear DC regulated power supply with a 0–30 V, 0–5 A output range. It features a 4-digit multicolour LED display for both voltage and current, automatic CV/CC mode switching, and a unique Output Pause function that allows live voltage adjustment while the output is switched off — so users can pre-set a voltage before connecting the load. Short-circuit and constant-current protection are built in. Suitable for bench-top laboratory, electronic service, and educational use.
Key Features
- 0–30 V, 0–5 A — single output, fully variable
- Linear (transformer-based) — very stable and reliable
- Automatic CV / CC mode switching
- 4-digit multicolour LED display for V and I
- Output On/Off (pause) — live voltage adjustment with output off
- Short-circuit and constant-current protection
- Input: 220 V AC ±10 %, 50 Hz
