How to Use Hanmatek HM310 DC Power Supply (Output Switch & USB)
1️⃣ What is an Adjustable DC Power Supply with USB Output?
The Hanmatek HM310 is a regulated adjustable DC bench power supply designed to deliver stable and controllable voltage and current for powering and testing electronic devices. It also includes a USB output port, allowing direct power supply to compatible USB-powered equipment.
Unlike fixed power adapters, the HM310 allows users to:
- Adjust output voltage and current precisely
- Enable or disable output using a dedicated output switch
- Power standard electronic circuits through binding terminals
- Power USB devices directly through the USB port
Purpose:
This type of power supply is commonly used in electronics testing, device repair, development work, and laboratory environments, where precise and flexible power control is required.
2️⃣ How it Works
The Hanmatek HM310 converts AC mains power into regulated DC output:
- AC-to-DC conversion — Internal circuitry converts incoming AC power into DC.
- Voltage regulation — Output voltage is stabilized at the user-defined level.
- Current limiting control — Maximum current is restricted to protect connected devices.
- Output switching — A front-panel switch enables or disables output safely.
- USB output regulation — Provides stable DC output suitable for USB-powered devices.
- Monitoring system — Voltage and current are displayed in real time.
The device automatically operates in constant voltage (CV) or constant current (CC) mode depending on load conditions.

Why these specifications matter:
- Output switch allows safe connection and disconnection of circuits.
- USB port provides convenient power for compatible devices.
- Adjustable output enables precise circuit testing.
- Current limiting prevents component damage.
- Real-time monitoring ensures safe operation.
4️⃣ Typical Use Cases
The Hanmatek HM310 is commonly used for:
✔ Powering and testing electronic circuits
✔ Repairing electronic devices
✔ Prototyping and development work
✔ Powering USB-powered modules or accessories
✔ Educational laboratory experiments
✔ Sensor and embedded system testing
✔ Controlled testing of small electronic loads
Example scenario:
A technician powers a prototype circuit using adjustable output terminals while simultaneously powering a USB microcontroller board from the built-in USB port.
5️⃣ How to Use the Device (Step-by-Step)
Step 1 — Power On
Connect the power supply to AC mains and turn on the main power switch.
Step 2 — Ensure Output is Disabled
Set the output switch to OFF before connecting a load.
Step 3 — Connect the Load
Attach output leads:
- Positive terminal → circuit positive
- Negative terminal → circuit ground
Verify correct polarity.
Step 4 — Set Output Voltage
Adjust the voltage control to the desired value.
Step 5 — Set Current Limit
Adjust current limit slightly above expected operating current.
Step 6 — Enable Output
Turn the output switch ON to supply power to the connected device.
Step 7 — Monitor Operation
Observe voltage and current readings.
If current reaches the preset limit, the device enters constant current mode.
Step 8 — Using the USB Output
Connect a compatible USB-powered device directly to the USB port.
Ensure total load does not exceed rated output capacity.
6️⃣ Best Practices for Safe Operation
- Always set voltage and current before enabling output.
- Keep output OFF while connecting or adjusting wiring.
- Double-check polarity before powering circuits.
- Increase voltage gradually when testing new circuits.
- Ensure proper ventilation around the power supply.
- Do not exceed USB or main output current ratings.
- Turn off output before disconnecting devices.
