AC Voltage Stabilizer MR 12000

Modalis MR 1200 AC Voltage Stabilizer 


Modalis MR 1200 single-phase AC voltage stabilizer is part of the Modalis product range of Standard series voltage stabilizers.

Modalis MR 1200 voltage stabilizer is designed for protection of home and office appliances and industrial equimpent with aggregate power consumption of up to  1.2 kVA (TV sets, PCs, fax machines, office telephone switchboards, etc). To power up across-the-line motors (found in fridges, washing machines, air pumps, compressor pumps, high-pressure washers, and power tools), the voltage stabilizer must have a reserve capacity that's 1.5-3 times greater than the motor's own capacity. 

Modalis MR 1200 voltage stabilizer is designed as a desktop unit with indicator display and power switch on the front panel, two European power sockets and automatic fuse on the back panel. It's equipped with a power cable with a Europlug.



     Design features:

  • desktop case;
  • toroidal power autotransformer;
  • double load protection from critically high input voltage;
  • automatic disconnection of autotransformer in case of input voltage surge over 300V with subsequent automatic reactivation once safe voltage has been restored;
  • self-cooling (no fan);
  • discrete (step-by-step) adjustment of output voltage;
  • wide range of input voltage;
  • high overload capacity;
  • relay power-switching circuits;
  • 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 voltage is restored to levels within the allowed range of operation;
  • output power filter to suppress high frequency distortions;
  • LED indicators of operating modes;
  • two European power sockets to connect the load, power cable with European standard plug to connect to the power circuit.
