30V / 5A (×2) + 2.2–15V / 1A Quad-Output Linear DC Regulated Power Supply

About.

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.

• 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
