- 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.
- సమగ్ర రక్షణ విధులు: Includes Over-Temperature Protection (otP), Instantaneous Over-Power Protection (oPP), Over-Voltage Protection (ouP), Reverse Polarity Protection, and Abnormal Power Supply Voltagఇ రక్షణ.
- Intelligent Fan Control: The cooling fan intelligently adjusts its speed based on the cooler's temperature, optimizing cooling efficiency and reducing noise.
4. సెటప్
Follow these steps to set up your DollaTek Electronic Load Module:
- విద్యుత్ సరఫరా కనెక్షన్: 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.
- లోడ్ కనెక్షన్: 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-.
- మౌంటు (ఐచ్ఛికం): 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).
- ప్రారంభ పవర్ ఆన్: After connecting the power supply and load, press the ON/OFF button to power on the module.

5.1 ప్రాథమిక ఆపరేషన్
- పవర్ ఆన్/ఆఫ్: 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.
- సర్దుబాటు పారామితులు: 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.
- డిశ్చార్జ్ కరెంట్: Adjustable from 0.20 A to 9.99 A, with steps of 0.1 A or 0.01 A.
- ముగింపు వాల్యూమ్tage: 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.
మూర్తి 3: Examples of display settings, including entering the function setting menu and buzzer on/off options.
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 బజర్ సెట్టింగ్లు
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.
