3.2 Mostra informació
The 2.8-inch TFT LCD provides real-time feedback on the power supply's status and output. Key information displayed includes:
- Establir el volum de sortidatage and Actual Output Voltage
- Set Output Current and Actual Output Current
- Actual Output Power
- Cumulative Running Time
- Channel Output Status (ON/OFF, CV/CC mode)
- Set values for Overvoltage Protection (OVP) and Overcurrent Protection (OCP)

When the actual current exceeds the set current value, the power supply automatically switches to Constant Current (CC) mode to protect the circuit.
3.3 Configuració Voltage i Actual
- Premeu el botó V botó per introduir el voltage setting mode. The voltage value on the display will become editable.
- Gira el Perilla d'ajust to change the desired voltage value. Press the knob to move between digits.
- Premeu el botó I button to enter current setting mode. The current value on the display will become editable.
- Gira el Perilla d'ajust to change the desired current value. Press the knob to move between digits.
- Un cop el vol desitjattage and current limits are set, press the On/Off button to enable the output.
3.4 Protection Functions (OVP, OCP)
The SPE6053 includes multiple protection features:
- Overvoltage Protecció (OVP): Prevents damage to the load by limiting the maximum output voltage. Premeu el botó OVP button to set the overvoltage límit.
- Protecció contra sobreintensitat (OCP): Protects the load from excessive current. Press the OCP button to set the overcurrent limit.
- Protecció contra curtcircuits: Automatically shuts down output in case of a short circuit.
- Over Power Protection: Limits the total output power.
- Protecció tèrmica: Protegeix la unitat del sobreescalfament.
It is recommended to set OVP and OCP values slightly above your desired operating voltage and current to provide a safety margin for your connected circuit.
3.5 Funcions de memòria
The power supply features 4 groups of memory parameters for quick recall of frequently used settings. Press the Memòria button to access these functions. Refer to the on-screen prompts for saving and recalling parameters.
3.6 USB Charging and PC Software Control
The front panel includes a 5V/1A USB output port for charging mobile phones or other compatible devices. Additionally, the rear USB communication port allows for firmware updates and control via PC software. This enables advanced programming and monitoring capabilities.
