This image shows the large radiator, intelligent temperature control fan, power entry terminal, 4-wire voltage interface, voltage display, Ah/Wh parameter indicators, setting bit indicator, adjustment knob, current display, and ON/OFF button.
Klíčové vlastnosti:
- Industrial Cooler: Equipped with a large-tooth industrial cooler, ensuring long-term operational stability even in dusty environments.
- Automatic Current Limiting: Maximum power of 60W with automatic current limiting. For example, at 6V, it can handle up to 9.99A, while at 20V, it limits to a maximum of 3.00A to stay within the 60W power envelope.
- High Battery Test Statistics: Capable of recording up to 999.9 Ah or 9999 Wh. The test automatically stops when either value is reached.
- Komplexní ochranné funkce: Includes Over-Temperature Protection (otP), Instantaneous Over-Power Protection (oPP), Over-Voltage Protection (ouP), Reverse Polarity Protection, and Abnormal Power Supply Voltage Ochrana.
- Inteligentní ovládání ventilátoru: The cooling fan intelligently adjusts its speed based on the cooler's temperature, optimizing cooling efficiency and reducing noise.
4. Nastavení
Follow these steps to set up your DollaTek Electronic Load Module:
- Připojení napájení: Connect a DC 12V power supply (0.5A or more) to the module's power entry terminal. Ensure the power supply uses a 5.5*2.1mm specification plug with inside positive and outside negative polarity.
- Načíst připojení: Connect the device or battery to be tested to the load terminals (P+ and P-). Ensure correct polarity: positive to P+ and negative to P-.
- Montáž (volitelné): The module has positioning holes at 60mm * 88mm with a 3.2mm diameter. It can be mounted using 5mm pad columns (copper for 60W version).
- Počáteční zapnutí: After connecting the power supply and load, press the ON/OFF button to power on the module.

5. Návod k obsluze
5.1 Základní obsluha
- Zapnutí/vypnutí: Press the ON/OFF button to turn the module on or off.
- Entering Settings Menu: Long press the ON/OFF button to enter the function setting menu.
- Nastavení parametrů: Use the adjustment knob (pushable) to navigate through settings and change values. Press the knob to confirm selections.
5.2 Setting Discharge Parameters
The module allows setting the discharge current and termination voltage. The display will show 'V' for voltage, 'A' for current, 'Ah' for Amp-hours, and 'Wh' for Watt-hours.
- Vybíjecí proud: Adjustable from 0.20 A to 9.99 A, with steps of 0.1 A or 0.01 A.
- Ukončení svtage: Adjustable from 1.0 V to 25.0 V, in increments of 1 V or 0.1 V. This is the voltage at which the discharge test will stop.

5.3 Starting and Stopping a Test
Once parameters are set, initiate the test. The module will discharge the connected battery or device at the set constant current until the termination voltage is reached, or the maximum Ah/Wh value is recorded.
- The test automatically stops when the set termination voltage is reached or when the statistical value (999.9 Ah or 9999 Wh) is met.
- The module provides real-time readings of voltage, current, and accumulated Ah/Wh during the test.
5.4 Nastavení bzučáku
The module includes a buzzer to signal events, such as reaching the termination voltage. You can enable or disable the buzzer through the settings menu.
- Long press the ON/OFF button to enter the settings menu.
- Navigate to the buzzer setting option (refer to Figure 3 for visual guidance).
- Use the adjustment knob to toggle the buzzer ON or OFF.
6. Údržba
- Čištění: Use a soft, dry cloth to clean the module. Do not use liquids or abrasive cleaners.
- Skladování: Modul skladujte na chladném a suchém místě mimo dosah přímého slunečního záření a extrémních teplot.
- Inspekce: Periodically check for any loose connections or visible damage to the components.
7. Řešení problémů
Tato část se zabývá běžnými problémy a jejich možnými řešeními.
| Issue/Error Code | Popis | Řešení |
|---|---|---|
| otP | Over-Temperature Protection activated. | Ensure adequate ventilation. Reduce the load or allow the module to cool down. Check if the fan is operating correctly. |
| oPP | Instantaneous Over-Power Protection activated. | The power drawn exceeds the 60W limit. Reduce the discharge current or increase the termination voltage to stay within the power limits. |
| ouP | Over-Voltage Protection activated. | Vstupní voltage is too high. Ensure the connected power source or battery voltage is within the module's operating range (1-30V). |
| Opačná polarita | Module does not power on or shows error. | Check the connections to the load and power supply. Ensure positive (+) and negative (-) terminals are connected correctly. |
| Abnormal Power Supply Voltage | Module does not power on or behaves erratically. | Verify that the input power supply is providing a stable 12V and at least 0.5A. |
| Ventilátor nefunguje | Cooling fan is not spinning. | The fan is intelligently controlled and only activates when the cooler temperature rises. If the module is hot and the fan is still not spinning, check for obstructions or fan malfunction. |
