Details:

The 201-100-sp is used on 95-120vac, 50/60hz motors to prevent damage caused by low voltage . The unique micro controller-based voltage and voltage -sensing circuit constantly monitors the to detect harmful power line conditions. The output relay reactivates after power line conditions return to an acceptable level and a specified amount of time has elapsed restart delay. The 201-200-SP-T-9 is a pin-for-pin replacement for time mark #260 series voltage monitor.

When a harmful condition is detected, the relays output relay deactivated after specified trip delay. The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. The 201-x-sp is an 8-pin octal-base, plug-in voltage monitor designed to protect single-phase motors regardless of size. The 201-200-sp is used on 190-240vac, 50/60hz motors.
