Model: 250A   |    Mpn: 250A   |    PartNumber: 250A   |   Asin: B0176L8N4A

SymCom MotorSaver model 250A is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-480VAC, 50/60Hz motors regardless of size. The product provides a user selectable nominal voltage setpoint and the voltage monitor automatically selects between the 200V and 400V range. This unique microcontroller-based voltage and phase-sensing device 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 acceptable levels. The Model 250A includes advanced single LED diagnostics. Five different light patterns distinguish between faults and normal conditions.

Features

DiversiTech DTP-3 Digital 3-Phase Motor Protector

Model: DTP-3   |    Mpn: DTP-3   |    Ean: 0686109880059   |    PartNumber: DTP-3   |   Asin: B008HQ3IT4

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
  • Small footprint & low profile fits where others can't
