About This Instrument
The Vartech 3005-4 is a quad-output transformer-based linear DC regulated power supply. It provides two fully variable channels (0–30 V / 0–5 A, Ch 1 & 2) and two auxiliary channels (2.2–15 V / 1 A, Ch 3 & 4). Four LED meters display V and I for the main variable channels. Preset voltage and current facility is included, along with Output On/Off switch. Designed for industrial and laboratory applications requiring multiple independent supply rails. Note: a lower-current variant (3003-4, 30 V / 3 A for Ch 1 & 2) is also available in the same chassis.
Key Features
- 4 independent output channels
- Ch 1 & 2: 0–30 V / 0–5 A (fully variable)
- Ch 3 & 4: 2.2–15 V / 1 A (auxiliary variable)
- Preset V & I facility
- Linear (transformer-based) — heavy duty
- 4 LED DPMs for V and I of the main channels
- Output On/Off switch | Auto CV/CC
