It can be used\n    on 95-120VAC (201-100-SP) or 190-240VAC (201-200-SP) motors to prevent\n    damage caused by low voltage. High voltage detection is included on the\n    201-200-SP-T-9 model. The unique microcontroller-based voltage and\n    voltage-sensing circuit constantly monitors the voltage to detect harmful\n    power line conditions. When a harmful condition is detected, the\n    MotorSaver's output relay is deactivated after a specified trip delay. The\n    output relay reactivates after power line conditions return to an\n    acceptable level and specified amount of time has elapsed (restart delay).\n    The trip delay prevents nuisance tripping due to rapidly fluctuating power\n    line conditions.\n\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse 201-100-SP Voltage Monitor Typical Applications\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFans\n\t\u003c\/li\u003e\n\u003cli\u003eCompressors\n\t\u003c\/li\u003e\n\u003cli\u003eAir Conditioners\n\t\u003c\/li\u003e\n\u003cli\u003eHeat Pumps\n\t\u003c\/li\u003e\n\u003cli\u003eWell Pumps\n\t\u003c\/li\u003e\n\u003cli\u003eSump Pumps\n\t\u003c\/li\u003e\n\u003cli\u003eSmall Conveyor Motors\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\nLittelfuse 201-100-SP Voltage Monitor Features\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLow Voltage Protection\n\t\u003c\/li\u003e\n\u003cli\u003eLow \u0026amp; High Voltage Protection Model Available\n\t\u003c\/li\u003e\n\u003cli\u003eDiagnostic LED\n\t\u003c\/li\u003e\n\u003cli\u003eUL508 Listed\n\t\u003c\/li\u003e\n\u003cli\u003eCE Marked\n\t\u003c\/li\u003e\n\u003cli\u003e8-Pin Plug In; DIN Rail or Surface Mount\n\t\u003c\/li\u003e\n\u003cli\u003e5-Year Warranty\n\t\u003c\/li\u003e\n\u003cli\u003eMade in USA\n\t\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Littelfuse\/Symcom","offers":[{"title":"Default Title","offer_id":49317861097789,"sku":"MSR201100SP","price":167.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/msrlf201xxxsp_001_wbg.jpg?v=1725295641"},{"product_id":"littelfuse-50r200-single-phase-voltage-monitor-190-240v","title":"Littelfuse 50R200 Single-Phase Voltage Monitor 190-240V","description":"\u003cp\u003e\n\u003cimg data-image=\"1l9tsjtw0igc\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/littelfuse1_logo.jpg\" title=\"Littelfuse your electronic and control \u0026amp; protection specialists\"\u003e\n\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse 50R200 Voltage Monitor Product Description\u003c\/h3\u003e\n\u003cp\u003e\n\tModel 50R200 Single Phase Voltage Monitor has a voltage sensing circuit which\n    constantly monitors the single phase power for a low voltage condition.\n    Single phase motors on fans, compressors, air conditioners, heat pumps,\n    sump pumps, and small conveyor motors are all applicable to the Model 50R.\n    When a harmful condition is detected the MotorSaver's output relay is\n    deactivated after the specified trip delay.

The 601-CS-D-P1 monitors ground fault current, phase currents, phase voltages, power factor and frequency. The RS485MS-2W communications module allows the 601-CS-D-P1 to communicate using the Modbus RTU protocol. The Modbus connection can be used to monitor power parameters, setup the device or control the fault relay. A DeviceNet™ communications I\/O module (CIO-601CS-DN-P1) is available as well. This CIO module only works with the 601-CS-D-P1 unit. It is used for sending the information from the 601-CS-D-P1 over a DeviceNet™ network.
