Product Overview
The Comet BL-A (Article No. 50-1003-012) from HORSTMANN is a single-pole, capacitive voltage indicator for the nominal voltage range of 6–10 kV. The device indicates the presence or absence of operating voltage via both optical and acoustic signaling and has an integrated self-test function that checks the circuit including the contact electrode.Function and Operation
- Indication: optical (1 red LED, 1 green LED) and acoustic (1 sounder) as specified for the BL-A variant.
- Integrated self-test for function control before use.
- Power supply: 2 lithium cells with a specified 6-year operational readiness under defined usage (10 readiness cycles/day and 230 working days/year).
Typical Applications
The Comet BL-A is used for the unambiguous determination of whether operating voltage is present or not present in the specified voltage range (6–10 kV). This includes control procedures where a visual and/or acoustic confirmation of the voltage status is necessary, as well as prior functional testing via the integrated self-test.Specifications
