4. Configuració
Follow these steps to set up your TekPower TP3010E power supply:
- Desembalatge: Carefully remove the power supply and all accessories from the packaging. Verify that all components are present: the TP3010E unit, power cord, and user manual.
- Col·locació: Place the unit on a stable, level surface with adequate ventilation. Ensure that the front and rear panels, especially the cooling fan, are not obstructed.
- Connexió d'alimentació:
- Ensure the power switch on the front panel is in the "OFF" position.
- Connect the provided AC power cord to the AC power input socket on the rear panel of the power supply.
- Plug the other end of the AC power cord into a grounded 110V AC outlet.
- Comprovació inicial: Before connecting any load, turn the power switch to "ON". The LCD display should illuminate and show voltage and current readings. Turn the voltage and current knobs to observe changes in the display. Then, turn the power switch to "OFF".
Figure 4.1: TP3010E Unit with Included Accessories.
This image shows the TekPower TP3010E power supply unit alongside its included accessories.

This illustrates the typical contents of the product package.
5. Instruccions de funcionament
The TP3010E operates in two modes: Constant Voltage (CV) and Constant Current (CC). The unit automatically switches between these modes depending on the load and the set voltage/current limits.
5.1 Configuració Voltage i Límits de corrent
- Encès: Ensure no load is connected to the output terminals. Turn the power switch to "ON".
- Set Voltage: Adjust the "VOLTAGE COARSE" knob to set the approximate desired voltage. Use the "VOLTAGE FINE" knob for precise adjustments. The LCD will display the set voltage.
- Set Current Limit (Pre-setting):
- Turn the "CURRENT COARSE" knob fully counter-clockwise (to minimum current).
- Momentarily short-circuit the output terminals using a test lead (connect positive to negative). The "C.C" indicator on the display should light up, and the current display will show the current limit.
- Adjust the "CURRENT COARSE" and "CURRENT FINE" knobs to set the desired maximum current limit for your application.
- Remove the short-circuit from the output terminals. The "C.V" indicator should light up, and the current display will drop to zero or near zero.
- Connectar càrrega: Connect your device or circuit to the output terminals (red to positive, black to negative).
- Funcionament: The power supply will now deliver the set voltage up to the set current limit. If the load draws more current than the set limit, the unit will switch to Constant Current (CC) mode, and the output voltage will drop to maintain the set current. If the load draws less current, it will operate in Constant VoltagMode e (CV).
5.2 Apagat
Before turning off the power supply, it is recommended to disconnect the load first, especially if the load is sensitive to voltage decay. The power supply's output voltage may decay slowly after the power switch is turned off due to internal capacitor discharge.
- Disconnect the load from the output terminals.
- Turn the power switch to "OFF".
- Unplug the AC power cord from the wall outlet if the unit will not be used for an extended period.
6. Manteniment
- Neteja: Feu servir un drap suau i sec per netejar l'exterior de la unitat. No utilitzeu productes de neteja abrasius ni dissolvents.
- Ventilació: Regularly check that the ventilation openings and the cooling fan on the rear panel are free from dust and obstructions. Use compressed air to clear dust if necessary.
- Substitució de fusibles: If the unit fails to power on, check the 8A fuse located in the fuse holder on the rear panel.
- Ensure the power supply is disconnected from the AC mains.
- Carefully remove the fuse holder cap.
- Replace the blown fuse with a new fuse of the same type and rating (8A).
- Securely replace the fuse holder cap.
- Emmagatzematge: When not in use for long periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| La unitat no s'encén. | No AC power; Blown fuse; Faulty power cord. | Check AC outlet and power cord connection. Replace 8A fuse if blown. |
| Display goes blank or flickers. | Internal transient condition; Loose internal connection (rare). | Turn off the unit, wait a few seconds, then turn it back on. If persistent, contact support. |
| Sense sortida voltage / actual. | Output terminals not connected; Voltage/current knobs set to zero; Unit in CC mode with no load. | Ensure load is connected. Adjust voltage/current knobs. Check if the unit is in CV mode (C.V indicator lit) when no load is present. |
| Volum de sortidatage drops significantly under load. | Unit is in Constant Current (CC) mode; Load resistance too low for set current. | Increase the current limit setting. Ensure the load's current draw does not exceed the power supply's maximum output (10A). |
| Cooling fan is running constantly or loudly. | High internal temperature; Fan obstruction. | Ensure adequate ventilation. Clear any obstructions from the fan grille. This is normal operation if the unit is under heavy load. |
