201-xxx-SP 是一款8引脚八脚基座插入式电压监控器,旨在保护各种尺寸的单相电机。201-100-SP 用于 95-120VAC 、50/60Hz 电机,防止因低电压造成的损坏。 The 201-200-SP is used on 190-240VAC, 50/60Hz motors. The 201-200-SP-T-9 is a pin-for-pin replacement for a Time Mark
® #260 Series voltage monitor. High voltage protection is included in the 201-200-SP-T-9.
The unique microcontroller-based voltage and voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the relay'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.
