Product details

GPD-The series of programmable linear DC power supplies adheres to the principle ofGW InstekConsistent technological and quality advantages in the field of power supply research and development production. Digital panel control, large display screen, brightLEDIndicator light, high output resolution4Group setting storageUSBThere are countless significant advantages such as remote control and intelligent temperature controlled fans. Not only is it easy to operate and supports multiple panel settings, but most importantly, it also has a reasonable price. With these advantages,GPD-The series is bound to become a shining new star in the power supply market.

high resolution

have1mV/1mA(GPD-2303S/3303S/4303S)High resolution and coarse tuning/Fine tuning the volume controlGPD-Series, ensuring clean and stable output. useGPD-Series, even with low voltage or current, you can accurately simulate the state of the test object, which cannot be achieved by low resolution power supplies.
Tracking in series/Parallel mode function
Tracking in series/Parallel function enablesGPD-The series has a wider range of uses. Tracking series mode ensures higher output voltage, while tracking parallel mode ensures higher output current.
Convenience features
The CNC knob can be fine tuned/Roughly adjust the volume setting. The lock key function locks the keyboard to avoid instrument damage caused by accidental settings.
4Group Save/Retrieval
GPD-Series can be saved/Retrieve panel settings, which are beyond the capabilities of typical power supplies. You can choose from4Quickly select a panel setting in the group memory settings, without the need for manual settings.
USBRemote control
GPD-Series ofUSB DevicePorts can remotely control power according to your application needs.
