| 460-XXX-SP SERIES - Single-phase voltage monitor |
Series Description: The 460-100-SP is used on 95–120 V ac, 50*/60 Hz single-phase motors and the 460-200-SP is used on 190–240 V ac, 50*/60 Hz single-phase motors to protect them from damaging high and low voltage conditions. An adjustment knob allows the user to set a 1–500 second restart delay. The variable restart delay is also a power-up delay and can be utilized to stagger-start motors on the same system.
A unique microcontroller-based, voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the MotorSaverÂ’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. |
- Proprietary microcontroller based circuitry: Constant monitoring of voltage to detect harmful power line conditions, even before a motor starts
- Fixed trip delay 4 s: Prevents nuisance tripping due to rapidly fluctuating power line conditions
- Adjustable restart delay (1–500s): Allows staggered start up of multiple motors on the same system to prevent a low voltage condition
- Advanced LED indication: Provides diagnostics which can be used for troubleshooting and to determine relay status
- DIN rail or surface mountable: Allows flexibility for panel assembly
