GW Instek GPE-1000 Series, Linear Benchtop DC Power Supplies Introduction
The GW Instek GPE-1000 series represents a new generation of linear DC power supplies designed for laboratory applications, component testing, and HiFi development. With a 2.4" TFT display, 1 mV setting resolution, and remote sensing functionality, they offer precision and versatility for every testing need.
- 2 available models: GPE-1205 (20V/5A/100W) and GPE-1323 (32V/3A/96W)
- 2.4" TFT LCD display for intuitive control and precise readings
- Setting resolution: 1 mV (voltage), 0.1 mA (current)
- Reading resolution: 0.1 mV (voltage), 0.01 mA (current)
- 4-wire remote sensing for voltage drop compensation up to 1V
- Series/parallel connection of two units of the same model
Target Applications
- Research & development, educational applications
