Description
Overview
The GW Instek GPS-3303 is a multi-channel linear DC power supply delivering 180W across three independent isolated channels. Channels 1 and 2 provide variable 0–30V/0–3A output, while Channel 3 provides a fixed 5V/3A output. All channels feature high regulation (0.01%) and low ripple/noise performance, making this unit ideal for complex test setups requiring multiple independent power rails.
Key Features
- Three independent isolated output channels
- Channels 1 & 2: 0–30V, 0–3A variable output
- Channel 3: 5V fixed, 3A maximum output
- Four LED digit displays (one per channel)
- 0.01% load and line regulation
- Low ripple and noise (<1 mVrms, 5Hz–1MHz)
- Tracking operation capability
- Auto series/parallel operation
- Output ON/OFF switch for load protection
- Series voltage tracking: 0–60V
- Parallel current tracking: 0–6A
- Fan speed control for minimal noise
- Overload and reverse polarity protection
- Optional European jack type terminal
Applications
- Multi-rail circuit development and testing
- Bench-top laboratory power delivery
- Educational setups requiring multiple voltage supplies
- Industrial testing with multiple independent loads
- Equipment maintenance and troubleshooting
