If you google the term 'breakdown voltage meter', you will find that although there is equipment that can measure this voltage, you have to pay hundreds to over a thousand euros for it. If you only occasionally feel the need to measure the breakdown voltage of a component, this small and inexpensive device offers a useful alternative to its much more expensive counterparts. That there is such a large ripple on the output voltage of 600 V may not be as it should be, but that probably has very little impact on measuring the breakdown voltage of a component.
Very nice and handy device to determine the breakdown voltage (BRV) of semiconductors, VDRs and such stuff. It comes without any manual. but use is quite straightforward: only connect the seiconductor union to be tested in reverse polarity, minimun current & voltage, and start increasing voltage slowly until display numbers stops increasing with voltage knob rotation. In the photo you can see a double diode with a BRV of 190 V. The other diode aside is a high voltage special one for microwave ovens with a BRV of 5 Kv, so it's out of range for measurement (voltage in mine reaches a maximun of 2720 V). Anyhow, a recommendable devide to have in the lab. Simple, but effective and a nice to have item. It came fully charged, so I was able to test it inmediately. Take advantage while flash sale lasts as it is at $21.99; more than 50% discount!
110V-2600V IGBT Transistor Voltage Capability Tester Diode MOS Triode Digital Voltmeter Testing Tool Withstand Voltage Tester - blue arrived before the agreed deadline. The shipment was well packed, the device is well made and works fine. I recommend the purchase.
Product delivered in good condition. Works great, everything OK.
Product is as described
Is very handy, Testing unmarked vdr's.. Also tested my own breakdown voltage! Not so handy...Normally using the Huntron tracker with comparison unit..but this tester has really high voltage.
The product is equal to the description, the transport was accurate. Thank you!
Very affordable high voltage tester for testing your semiconductor parts or capacitors ! Great !!!
good product only if it took 2 months on delivery.
Practical tool for service. Quality and functional.
