GW Instek GPE-1205 / GPE-1323 - Single Channel Linear DC Power Supply
Honoring 40 Years of Legacy, Evolving for the Future.
For battery-operated electronic products, high-quality audio circuits (amplifiers and speakers), and other similar applications, the low ripple & noise and fast transient response characteristics of linear power supplies make them the preferred choice for testing these applications. GW Instek's GPS-1850D, GPS-3030D, and GPS-3030DD 90 W linear power supplies have long-standing reputations in the industry. Due to the discontinuation of components such as LED displays and variable resistors (VR) for these three products, GW Instek introduces two models, GPE-1205 and GPE-1323, to replace these three 90 W products in the existing market, with the following new features:
Resolution
0.1 mA
Ripple & Noise
(5 Hz to 1 MHz)
Recovery Time
(50 % load change, minimum load 0.5 A)
- Power increased from 90 W to 96 W and 100 W
- New encoder switch to replace VR (variable resistance)
- 2.4" TFT LCD to replace LED
- Provided hardware protections: OVP · OCP · OTP · On/Off switch · Key Lock
- Voltage setting resolution 1 mV · Current setting resolution 0.1 mA
- Voltage readback resolution 100 µV · Current readback resolution 10 µA
- Provided Remote Sense (compensates voltage up to 1 V)
- Can perform series/parallel connection of two GPE-1000 units of the same model through the rear panel Control I/O interface
- 2.4" TFT LCD
- Encoder switch to set up voltage and current
- Voltage setting resolution 1 mV
- Voltage readback resolution 100 µV
- Current setting resolution 0.1 mA
- Current readback resolution 10 µA
- Provided hardware protections: OVP · OCP · OTP · On/Off switch · Key Lock
- Provided Remote Sense (compensates voltage up to 1 V)
- Can perform series/parallel connection of two GPE-1000 units of the same model through the rear panel Control I/O interface
