产品介绍
Symcom欣控 355-400 电机控制
SymCom 355-400 MotorSaver
355-400
In Stock. Unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltage to detect harmful power line conditions such as single-phasing, high voltage, low voltage, phase reversal, voltage unbalance, and high voltage (optional). 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 for a specified amount of time (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. Protects 3-Phase Motors From: Loss of any phase (single-phasing) Low voltage High voltage Voltage unbalance Phase reversal Additional Features: Three input voltage ranges provide the versatility to handle global applications. Four adjustment pots provide flexibility for numerous applications Diagnostic LEDs indicate trip status and make troubleshooting a snap. The microcontroller-based circuit provides better accuracy and higher reliability than analog designs. Transient protection meets IEC 1000-4-5:1995 standards to handle tough conditions. Single-phase conditions are detected regardless of regenerated voltages. Diagnostic LED indicates: Run, Restart delay, Reverse phase, Unbalance/single-phase, High/low voltage Standard surface mount UL and cUL listed 5-year warranty Made in the USA
