Common questions about manuals, registration, and support for this brand.
To operate in constant voltage mode, set the desired output voltage using the coarse and fine adjustment knobs while ensuring the external load does not exceed your set current limit. The CV indicator light will illuminate when it is in this state.
The OCP (Over-Current Protection) short-circuit alarm sounds when the load equipment is short-circuited. Remove the short circuit from your external load, then press the output button to release the alarm and restore the output status.
Yes, most modern Hangell DC power supply models are equipped with USB and Type-C fast-charging interfaces that automatically adjust output voltage up to 18W depending on the connected device's charging protocol.
The internal cooling fan on Hangell bench power supplies is typically temperature-controlled. It will start spinning automatically only when the chassis temperature reaches a specific threshold required for heat dissipation.
