5. Operating Instructions

The SPS-3010X features an intuitive single encoder knob for precise adjustments and a clear 4-digit LED display for real-time monitoring.

5.1 Adjusting Voltage and Current

1. Turn on the power supply using the main power switch on the back.
2. Press the 'V' button to enter Voltage Adjustment Mode. Rotate the central encoder knob to adjust the voltage value. Press the knob to select the digit you wish to change.
3. Press the 'A' button to enter Current Adjustment Mode. Rotate the central encoder knob to adjust the current value. Press the knob to select the digit you wish to change.
4. The 4-digit LED display will show measured values of V, A, and W in real-time.

5.2 Output ON/OFF Control

Press the 'OUT' button to enable the output. The 'ON' indicator light will illuminate. Press the 'OUT' button again to disable the output; the 'ON' indicator will turn off. This allows for safe adjustment of settings without disconnecting the load.

5.3 Standby Mode

Press the 'Standby' button to enter Low-power Standby mode. The display will turn off, with only the 'MEN' indicator remaining on. This is useful for short breaks. Press the 'Standby' button again to resume operation.

6. USB Charging Ports

The Jesverty SPS-3010X is equipped with both USB-A and Type-C charging ports, each supporting 20W fast charging. These ports are ideal for conveniently charging your mobile devices or powering small electronic projects like Arduino UNO or Raspberry Pi directly from the power supply.

7. Preset Memory Function

The Preset Memory function allows you to store and quickly recall up to 5 groups of frequently used voltage and current settings. This feature is particularly useful for repetitive tasks or projects requiring specific power configurations.

7.1 Storing and Recalling Settings

1. Adjust the desired voltage and current using the encoder knob.
2. Long press the 'Standby' button to enter the Preset Memory function.
3. Use the encoder knob to select a memory slot (EE01-EE05).
4. To save the current settings to the selected memory slot, long press the 'MEN' button.
5. To recall settings from a memory slot, select the desired slot and then press the 'OUT' button. The stored values will be output.

8. Over-Current Protection (OCP)

The OCP function protects your connected devices by automatically cutting off the output if the current exceeds a user-defined limit. This feature is settable.

8.1 Configuring OCP

1. Long press the 'A' button to enter the OCP configuration mode.
2. Rotate the knob to set the value from '0' to '1' to enable the OCP function. (0 = disabled, 1 = enabled).
3. Press the 'A' button again and use the knob to set the OCP trip point (the maximum current allowed).
4. Long press the 'A' button again to return to the main interface.

When the actual output current exceeds the set OCP trip point, the output will be cut off immediately, and the 'OCP' indicator will blink, showing that the OCP function has been activated.

8.2 Disabling OCP

1. Long press the 'A' button to go back to the OCP configuration mode.
2. Rotate the knob to set the value from '1' to '0' to disable the OCP function.
3. Long press the 'A' button again to return to the main interface. The 'OCP' indicator will go off.

9. OPN (Output Power ON) Function

The OPN function allows the unit to automatically output voltage and current as soon as the power switch is turned on, without needing to press the 'OUT' button. Use this function with caution.
