1. Transformer Selection
The WMPC124 module requires an external AC transformer or a DC power source. The choice of transformer depends on the desired DC output voltage. Refer to the table below for guidance:

Figure 3: Transformer rating guide.
Recommended Transformers:
- For 3-6VDC output: 9Vac transformer (e.g., 109010C: OPEN-FRAME TRANSFORMER 10.8 VA 1 x 9 V~ 1200 mA max.)
- For 6-9VDC output: 12Vac transformer (e.g., 112012C: OPEN-FRAME TRANSFORMER 12 VA 1 x 12 V~ 1000 mA max.)
- For 9-12VDC output: 15Vac transformer
- For 12-15VDC output: 18Vac transformer
- For 15-21VDC output: 24Vac transformer (e.g., 212024C: OPEN-FRAME TRANSFORMER 24 VA 2 x 12 V~ 1000 mA max.)
2. රැහැන් සම්බන්ධතා
- ආදාන සම්බන්ධතාවය: Connect your chosen AC transformer (or DC power source) to the ආදානය screw terminals on the right side of the module. Ensure the input voltage does not exceed 24 VAC or 35 VDC. For AC input, polarity is not critical. For DC input, observe the '+' and '-' markings if present, though the module's rectifier bridge allows for some tolerance.
- ප්රතිදාන සම්බන්ධතාවය: Connect your load (e.g., DC motor, low-voltage light bulb, project circuit) to the ප්රතිදානය screw terminals on the left side of the module. Observe the '+' and '-' polarity markings carefully.
3. Initial Adjustment
Before applying power to your load, it is recommended to set the output voltage to its minimum. Use a small screwdriver to turn the potentiometer (labeled 'Vout Adj.') fully counter-clockwise. This will set the output to approximately 1.2V.
Operating the Module
- බල ගැන්වීම: Once all connections are secure and verified, apply power to the input terminals.
- ප්රතිදාන පරිමාව සීරුමාරු කිරීමtage: Connect a multimeter to the output terminals to monitor the voltage. Slowly turn the potentiometer clockwise to increase the output voltage to your desired level (between 1.2V and 30V).
- වත්මන් සීමාව: The module is rated for a maximum output current of 1A. Do not exceed this limit to prevent damage to the module or connected devices.
- විදුලිය විසන්ධි කිරීම: Disconnect the input power when the module is no longer needed.
නඩත්තු කිරීම
- මොඩියුලය පිරිසිදුව හා දූවිලි හා සුන්බුන් වලින් තොරව තබා ගන්න. පිරිසිදු කිරීම සඳහා මෘදු වියළි රෙද්දක් භාවිතා කරන්න.
- Regularly inspect all wiring connections to ensure they are tight and secure.
- Store the module in a dry, cool environment when not in use.
- Avoid physical shock or excessive vibration.
දෝෂගවේෂණය
- ප්රතිදාන වෙළුම නැතtage:
- Check if input power is correctly applied and within specifications.
- Verify input and output wiring for correct connections and polarity.
- Ensure the potentiometer is not set to its absolute minimum (though it should still provide ~1.2V).
- Inspect for any visible damage to components (e.g., burnt resistors, bulging capacitors).
- වැරදි ප්රතිදාන පරිමාවtage:
- Recalibrate the output voltage using a multimeter and the potentiometer.
- ආදාන පරිමාව සහතික කරන්නtage is stable and sufficient for the desired output.
- මොඩියුලය අධික ලෙස රත් වීම:
- Reduce the load current to stay within the 1A maximum.
- Ensure adequate ventilation around the module.
- ආදාන පරිමාව බව තහවුරු කරන්නtage is not excessively high for the desired output, leading to higher power dissipation.
