AC voltage stabilizer Modalis MR 400

 

Modalis MR 400 AC voltage stabilizer

 

Modalis MR 400 voltage stabilizer is designed for protection of home and office appliances and industrial equipment with aggregate power consumption of up to 400 VA (TV sets, PCs, fax machine, office phone switchboards, etc). To power up across-the-line motors (found in refrigerators, washing machines, air pumps, compression 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 400 voltage stabilized is designed as a desktop unit with indicator display and power switch on the front panel, two European standard sockets and automatic safety on the back panel. There's a cable with European standard plug for power connection.

 

Design features:

  • desktop case;
  • toroidal power autotransformer;
  • double load protection from critically high input voltage;
  • automatic disconnection of the autotransformer in case of input voltage surge over 300V with subsequent automatic reactivation once a safe voltage has been restored;
  • self-cooling procedure (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;
  • abiility to work at declared load power within the entire range of input voltages;
  • automatic power cutoff when input of output voltage exceeds the preset threshold with subsequent automatic reactivation after the voltage is restored to levels within the allowed range of operation;
  • output power filter to suppress high frequency distortions;
  • LED indicator of operating modes;
  • two European standard sockets for load connection, cable with a European standard plug for power connection.
