AC Voltage Stabilizator Modalis MR3000

Modalis MR 3000 AC Voltage Stabilizer

 

Modalis MR 3000 single-phase AC voltage stabilizer is part of the Modalis product range of Standard series voltage stabilizers.

Modalis MR 3000 voltage stabilizer is designed for protection of  home and office appliances and industrial equimpent with aggregate power consumption of up to  3 kVA (microwave ovens, air pumps, compressor pumps, copy machines, etc). To power up across-the-line motors (found in refrigerators, washing machines, air pumps, high-pressure washers, and power toold), the voltage stabilizer must have a reserve capacity that's 1.5-3 times greater than the motor's own capacity. 

Modalis MR 3000 voltage stabilizer is designed as a desktop unit with indicator display and power switch on the front panel and screw terminal for connecting power supply and load cables on the back panel.

 

 

 

 

  

     Design features:

 
  • desktop case;
  • toroidal power autotransformer;
  • self-cooling (no fan);
  • discrete (step-by-step) adjustment of output voltage, closed transition; 
  • wide range of input voltage;
  • high overload capacity;
  • relay power-switching circuits;
  • 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 voltage is restored to levels within the allowed range of operation;
  • output power filter to suppress high frequency distortions;
  • LED indicators of operating modes;
  • screw terminal for connecting power supply and load cables.
