Product Overview
This single-pole, capacitive voltage detector Comet BK-I from HORSTMANN features a truncated design and is intended for indoor use under dry conditions. The device provides visual indication using red and green LEDs, and for variant 50-1303-002, both visual and acoustic indication (buzzer) for the voltage range 10–20 kV. The Comet BK-I has a built-in self-test, which checks the circuit including the contact electrode before use, and is powered by two lithium cells with an operating temperature range from −25 °C to +70 °C.
