Description
The TSV101 is a durable AC voltage detector that uses only electronic components, foregoing mechanical parts for enhanced longevity. It offers an opto-isolated open collector output, providing galvanic isolation, and can detect voltage in two ranges—85 to 250 VAC and 170 to 250 VAC—selectable via an internal jumper. Designed for versatility, this detector is powered solely by the monitored voltage and is ideal for sensing line voltage presence or absence in UPS systems, power supplies, electrical sources, and power lines, with a DIN rail mountable design for quick and secure installation.

Detection Level Change
The detection level can be changed by jumper which is inside the box, on the PCB. If the jumper is open detection level is 85vAC, if it is closed, detection level is 170VAC. New devices come with the jumper closed and detection level is 170VAC.
