TSV101
Teracom TSV101: AC Voltage Detector for Marine UPS & Automation Systems
TSV101 is a sturdy AC voltage detector that uses galvanic isolation and an optoisolated open-collector output to protect downstream equipment. Users can choose between two detection bands-85 to 250 VAC or 170 to 250 VAC-by moving an internal jumper. Being powered directly from the line voltage under test, TSV101 eliminates the hassle of a separate supply. The isolated photocoupler output lets technicians share the status signal with confidence. Intended for UPS checks, power-supply supervision, or simple line monitoring, the detector mounts neatly on standard DIN rails, placing it within easy reach in panels and control cabinets.
