Modalis MR 9000-3 AC voltage stabilizer

 

 

Стабилизатор переменного напряжения Modalis MR 9000-3Modalis MR 9000-3 three-phase AC voltage stabilizer is part of the Modalis product range of Standard series voltage stabilizers.

Modalis MR 9000-3 voltage stabilizer is designed to protect home and office appliances and industrial equipment with aggregate power consumption of up to 9 kVA (electric motors, air pumps, refrigerators, industrial machines, etc). To power up induction motors (found inside industrial machines, refrigerators, air pumps, compression pumps, high-pressure washers), the voltage stabilizer must have a reserve capacity that's at least three times greater than the motor's own capacity. 

Modalis MR 9000-3 voltage stabilizer has two ports for external power input. One of the ports has a built-in safety that automatically switches off the device when there's no voltage in one of the phases, and the other one has no such option. Modalis MR 9000-3 voltage stabilizer is a wall-mounting monobloc unit with an indicator panel and automatic power switch on the front panel, and a terminal block for connecting power and load cables on the back panel. 

 

Design features:

  • wall-mounting enclosure;
  • toroidal power autotransformer;
  • ambient cooling (no fan);
  • discrete (step-by-step) adjustment of output voltage;
  • wide range of input voltage;
  • high overload capacity;
  • relay power switches;
  • fast response time;
  • electronic overload and short-circuit protection featuring automatic disconnection;
  • ability to work at declared load power within the entire range of input voltages;
  • automatic power cutoff when input or output voltage exceeds the preset threshold with subsequent automatic reactivation after the voltage is restored to levels within the allowed range of operation;
  • additional port with built-in safety switch to turn the device off in case of voltage loss;
  • output power filter to suppress high frequency distortions;
  • LED indicator of operating modes;
  • screw terminal for connecting power supply and load cables.
