The Kewprove 3 Proving Unit is essential for proving circuits are dead before commencing work. The high output will drive low impedance testers such as traditional test lamps as well as modern two pole testers - the one to have to be confident that it will work with your tester. It even steps down through the voltage stages to prove each stage as well.

Features:

• 50-690 V proving unit with just two terminals to test AC and DC voltage detectors
• High output will drive even the most high current voltage detector
• Instant ramp up and then step down will prove several voltage levels
• Essential for proving that circuits are not live when working on electrical circuits
• LED indication of functioning unit
• Makes a perfect partner to the KEW1700 / 1710 voltage testers
