The 202 200 SP series voltage monitor is designed to protect single-phase motors regardless of their size. It can be used with 190–240 V ac, 50*/60 Hz motors to prevent damage caused by incoming power problems. A unique microcontroller-based, voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver’s output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level and a specified amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.
*Note: 50 Hz will increase all delay timers by 20 %.
- Proprietary microcontroller-based circuitry
- Fixed trip delay 4 s
- Adjustable restart delay (manual, 2–3 s)
- Advanced LED indication
- One screw mounting and standard ¼” quick-connect terminals
- Constant monitoring of voltage to detect harmful power line conditions - even before a motor starts
- Prevents nuisance tripping due to rapidly fluctuating power line conditions
- Allows staggered start-up of multiple motors after a fault to prevent a low-voltage condition
- Provides diagnostics that can be used for troubleshooting and to determine relay status
- Fast installation and compact size are perfect for panel assembly or OEM applications
