Telegram : @zeusmining_presalesThe optocoupler test instrument is used for online testing of optocoupler faults on ASIC miner power supplies. It is equipped with elastic probes and test pads. It is compact and convenient and can be operated and tested with one hand. This test pad can directly place ordinary plug-in optical couplers and is compatible with most four-corner optical couplers for online testing, including 817, 781, 521, and other plug-in patches.
This tester can be used to test the optocoupler of Antminer, Whatsminer, Avalon, Innosilicon, and IceRiver power supply.
The SMD test soldering pad is 11*4mm in size. It can test a patch optical coupler up to 7.6*3.6mm (excluding pins) and a minimum of 3.8*2mm (excluding pins).
Applicable methods:
1. During the test, confirm that the board being tested has been powered off and that the large electrolytic capacitor on the motherboard has been fully discharged. It is strictly prohibited to test when the motherboard is powered on;
2. Confirm that the No. 1 pin of the optocoupler (the pin with a small dot) also has the corresponding pin No. 1 mark on the test board;
3. Connect the optocoupler test board to the USB power cord, and the probe of the test board contacts the optocoupler to be tested. If the indicator light on the optocoupler test board keeps flashing, it means the optocoupler is good (the brightness of the indicator light may be different; as long as it flashes, it means the optocoupler is good);
4. When measuring, ensure that the optocoupler test board has good contact with the optocoupler under test;
5. If the indicator light is always on or off, you can remove the optocoupler from the circuit board and insert it into the optocoupler holder of the test board to confirm the test results again;
6. Applicable to 4-pin optocouplers; other types of optocouplers are not applicable for now.
When you purchase this product, we will provide an extra Type-C data cable for the computer to power the optocoupler module and conduct a test.
