CONVERTER MODULE
Think It… Make It… Invent!
SKU: PROD0194


Product Description

This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module,capable of driving a 5A load with high
efficiency, low ripple and excellent line and load regulation.The module has a voltmeter display to show the current input
and output voltages. It can also be calibrated for accuracy.
Performance parameters

2. Output voltage range? 1.25-36VDC adjustable
3. Output current: 0-5A
4. Output power: 75W
5. voltmeter range: 4 to 40V, error ±0.1V
6. Operating frequency: 180KHz
7. High efficiency up to 96%
8. Built in thermal shutdown function
9. Built in current limit function
10. Built in output short protection function
11. L x W x H = 6.6*3.9*1.8CM
Voltmeter calibration method:

1. Output voltage calibration steps

Step 1:
Press the right button so that “”OUT”” LED lights, the voltmeter shows the current value of output voltage. Press
and hold the right button for more than 2 seconds, release, voltmeter and “”OUT”” LED flashes in synch which means
you’re in output voltage calibration mode.

Step 2:
Pressing the right button (normal speed), the voltage value will increment by 1. Pressing the left button, will
decrement the voltage reading by 1. Since the display can only show .1V steps minimum during calibration, you
might need to press the adjustment buttons 1-5 times for the display to change by .1V. Pressing the buttons once
increments or decrements the actual value by less than .1V hence the 1-5 presses.

Step 3:
Once calibration is done, press and hold the right button again for 2 seconds to exit calibration mode. The set
values are automatically saved even after removing power.

2. Input voltage calibration steps

Step 1:
Press the right button so that “”IN”” LED lights, the voltmeter shows the current value of input voltage. Press and hold the
right button for more than 2 seconds, release, voltmeter and “”IN”” LED flashes in synch which means you’re in input voltage
calibration mode. Follow steps 2 and 3 of output voltage calibration steps.
