5.1 Wiring the Module
The WEL3005 module requires careful wiring to ensure proper operation and accurate measurements. Refer to the diagram below for correct connections.
- Электр камсыздоо: Connect a 6V-30V DC power source to the module's supply input.
- Туташуу жүктөө:
- Connect the positive terminal of the device under test (e.g., battery) to the "B+" terminal for current measurement.
- Connect the negative terminal of the device under test to the "B-" terminal for current measurement.
- Voltage measurement leads are connected to the appropriate B+ and B- terminals for voltagэ сезүү.
- The module features input anti-reverse protection, but always double-check polarity before powering on.
5.2 Баштапкы кубаттуулук
- After wiring, turn on the module using the rotary encoder.
- The color display will illuminate, showing current readings and status.
- The fan will automatically start if the internal temperature exceeds 45°C.
6. Иштөө нускамалары
6.1 Adjusting Discharge Current
- Use the rotary encoder to continuously adjust the discharge current from 0A to 5A.
- Rotate clockwise to increase current, counter-clockwise to decrease.
- Observe the display for real-time current values.
6.2 Monitoring Parameters
The color display shows the following parameters:
- Тtage (U)
- Учурдагы (I)
- Күч (P)
- Сыйымдуулугу (Ах)
