About This Instrument
The Vartech 3020 is a heavy-duty single-output linear DC power supply rated 0–30 V, 0–20 A. It adds a preset voltage and current facility (not on the 3010), allowing users to pre-set output values before enabling the output. CV/CC automatic switching, Output On/Off, and series/parallel connection capability make it suitable for high-current bench and industrial applications.
Key Features
- 0–30 V, 0–20 A — single output, fully variable
- Linear (transformer-based) — heavy duty
- Preset V & I control facility
- Automatic CV / CC mode switching
- Output On/Off switch
- Series / parallel connection capability
- Constant current and overload protection
