The over voltage protection module is intended for protecting systems powered with 12V DC against being supplied with too high supply power (e.g. as a result of damaged stabilising system of a PSU). When the maximum accessible input voltage is detected, the output is cut off protecting the receivers from damaging. Activation of the system is indicated by the red LED – L1. Protections against overvoltage OVP. The module board is mounted on a plastic base plate, which can be mounted to a flat substrate by means of two screws or integrated adhesive tape. voltage: 9V-40V DC. Output voltage: 9V ÷ 14,1V DC (+/-0,4V). Output disconnection voltage: 14,1V (+/-0,4V). Load current 4A max. LED indication. Operating temperature: -10°C..50°C. Dimensions: 50 x 43 x 26 mm.
