Voltage Sensor

Product catalog summary

Description: The Model 160B(R) Voltage Sensor is designed to detect over or under voltage conditions. It features a single set-point mechanism where input voltages above the setpoint energize the output contacts, and voltages below de-energize them. The dead band between pull-in and drop-out is less than one percent. Wiring is facilitated through 1/4” quick connect terminals, and the device includes a 2-second restart delay, with 'R' versions offering a 5-minute delay. The setpoint range is adjustable to approximately 35% of the maximum voltage, and it operates across frequencies from 50 to 400 Hz.

Specifications: The Model 160B is available in three versions: 160B120 (120VAC), 160B240 (208/240VAC), and 160B480 (480VAC). The AC adjustment ranges are 80-130V, 160-250V, and 380-480V respectively. It features a short cycle delay of 2 seconds (5 minutes for 'R' versions), set-point stability of ±1%, and a dead band of approximately 5%. The trip delay is fixed at 0.5 seconds, and the contact rating is SPDT 10A at 240VAC resistive. The relay life expectancy is 10 million mechanical operations and 100,000 electrical operations at rated load. The device operates within a temperature range of -40º to +131º F and offers transient protection of 2500V for 10ms. It is housed in an ABS plastic enclosure and weighs 4 oz.

Installation: The Model 160B is a surface-mounted device that can be installed in any convenient location. Connections are made using 1/4” terminal lugs. For under-voltage sensing, connect the load control circuit to the terminal marked C and NO, and for over-voltage sensing, connect to C and NC. Adjustments can be made to set the desired trip point for under or over-voltage conditions.

Troubleshooting: If the sensor fails to operate, verify all connections, ensure the correct source voltage is present, and check all fuses. Persistent issues should be directed to the factory for assistance.

Safety: The device contains potentially hazardous voltages at its terminals. All electrical power should be removed when connecting or disconnecting wiring. Installation and servicing should be performed by qualified personnel.

Warranty: The Model 160B is warranted to be free from defects in materials and workmanship for one year from the date of purchase. Repair or replacement is available under warranty conditions.
