SymCom MotorSaver 3-Phase Voltage Monitor, Model 455, 190-480V, Line and Load Side Monitoring, SPDT Output Relay

Model: 455   |    Mpn: 455   |    PartNumber: 455   |   Asin: B0176L8A2A

SymCom Model 455 3-phase voltage monitor combines load and line-side monitoring to alert the user of contact failure or impending contact failure. The line-side monitoring will protect the motor from damaging line-side conditions prior to the motor starting. With other line/load-side voltage monitors, the motor must be started before a voltage problem is detected. With the Model 455, your motor is fully protected at all times. The motor will not start if a power problem is present. The Model 455 (190-480VAC) is equipped with one SPDT 480VA @ 240VAC output relay and feature an adjustable trip delay (2-30 seconds), restart delay (manual, 2-300 seconds), and voltage unbalance trip point (2-8%). The status of the Model 455 can be easily identified by the four LEDs on the front of the device: Run, Undervoltage, Overvoltage, and Phasing Fault or by using the Informer-MS, which, in addition to present status, will display live voltages, last 20 faults, last 32 motor starts, and motor run hours.

Features

  • Protects 3-phase motors from contact failure, loss of any phase (single-phasing) on the load or line side, low voltage, high voltage, voltage unbalance, phase reversal, and rapid cycling
  • Four adjustment pots provide versatility for a variety of applications
  • Both load and line-side monitoring provides contactor protection
  • Diagnostic LEDs indicate trip status and provide simple troubleshooting
  • UL and cUL Listed

Symcom MotorSaver 3-Phase Voltage Monitor, Model 201A-AU, 190-480V, Variable Trip Point, Restart Delay, Trip Delay, and Voltage Unbalance, 8-Pin Octal Base

Model: 201A-AU   |    Mpn: 201A-AU   |    PartNumber: 201A-AU   |   Asin: B0176L8I0O

SymCom Model 201A-AU is a versatile, plug-in style voltage monitor designed to protect 3-phase motors from damaging power conditions. Its wide operating range combined with UL, cUL and CE compliance enables quick access to domestic and global markets. A unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltages 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 for the specified restart delay. The trip and restart delays prevent nuisance tripping due to rapidly fluctuating power line conditions. The Model 201A-AU automatically senses whether it is connected to a 190-240V, 60Hz system, a 440-480V, 60Hz system, or a 380-416V, 50Hz system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480VAC. Other variable settings include a 1-30 second trip delay, manual or 1-500 second restart delay, and 2-8% voltage unbalance trip point

DiversiTech DSP-1 Corporation Digital Single Phase Line Voltage Monitor

Model: DSP-1   |    Mpn: DSP-1   |    PartNumber: DSP-1   |   Asin: B008HQ3IJ4

DSP-1 is an automatic voltage monitor and controls for three phase powered equipment. By continuously measuring the incoming line voltage, this monitor will detect any voltage outside the tolerances you set. If the limits that you set are exceeded, the response timer will begin counting. You also have the flexibility to set the response timer -- a shorter time may be desired to avoid nuisance tripping. If the voltage remains outside the tolerance after the response time has elapsed, the DSP-1 will turn off its output relay and protect your device. While the output is off, an additional delay timer is activated to avoid rapid re-starts.

Features

  • Digital voltmeter displays instantaneous line voltage
  • Automatic voltage tester adjusts from 90 to 300 volts
  • Adjustable response timer (0.1 to 10 sec.) prevents nuisance tripping
  • Adjustable delay timer (1 to 720 sec.) prevents rapid re-starts
  • Digital display makes for easy viewing and operation

The DTP-3 is an automatic digital voltage monitor and control system. By continuously measuring the line voltage, The DTP-3 monitor will detect voltages outside of the tolerance you set. If these limits are exceeded, the response timer is started. This timer may be set to a long time value to avoid nuisance tripping, or to a short time value to offer a higher level of load protection. If the voltage remains outside of the selected tolerance after the time has elapsed, DTP-3 will turn off its output relay and protect your device. While the load is off, an additional lockout timer is activated to avoid rapid restarts.

Features

  • Super simple Operation with 3 button set-up
