Frequently Asked Questions - GPW-005 GW Instek
How do I set the output voltage and current on the GPW-005?
The GPW-005 allows you to adjust voltage and current using the rotary knob and keypad. Press the voltage or current key, enter the desired value, and press Enter. The output will update when you enable the output.
What is the difference between CV and CC mode?
In Constant Voltage (CV) mode, the supply maintains the set voltage while current varies with the load. In Constant Current (CC) mode, the current is held constant and the voltage adjusts. The front panel indicates the active mode.
Can I connect multiple power supplies in series or parallel?
Yes, multiple units can be connected in series for higher voltage or in parallel for higher current, but follow the instructions in the manual for proper wiring and ensure the reverse polarity protection is respected.
How do I use the remote sensing function?
Remote sensing compensates for voltage drops in the test leads. Connect the sense terminals directly to the load. This ensures the output voltage at the load matches the set value.
What is the maximum input voltage for the device?
The power supply accepts an input voltage of 100-240 VAC, 50/60 Hz, so it can be used on standard mains supplies worldwide.
How do I clean the device?
Before cleaning, disconnect the power cord. Use a dry, soft cloth to wipe the exterior. Avoid using solvents or water to prevent damage.
What protective features does the GPW-005 include?
The power supply includes overload, short circuit, and over-temperature protection to safeguard both the unit and your application.
How can I update the firmware?
Firmware updates are not typically user-performed. Contact GW Instek technical support for assistance if required.
What is the accuracy of the output voltage?
The manual specifies voltage and current accuracy of about ±(0.1% of output + 5mV) and ±(0.2% of output + 5mA) after calibration. Refer to the specification table in the manual.
How do I reset the GPW-005 to factory defaults?
Use the 'System' menu and select 'Factory Reset'. Confirm the action; the device will restore factory settings.
