AC Voltage Stabilizer Modalis MR800


Modalis MR 800 AC Voltage Stabilizer


Modalis MR 800 single-phase AC voltage stabilizer has a power capacity of 800 VA and has been designed to provide high quality power supply for circulation pumps, automatic controls in gas boilers, audio/video equipment and other home appliances.

Modalis MR 800 voltage stabilizer is designed as a wall-mounted unit with an indicator panel, two European power sockets, automatic fuse and power switch.


Design features:


  • self-cooling;
  • toroidal power autotransformer;
  • discrete (step-by-step) adjustment of output voltage;
  • high overload capacity;
  • extended range of acceptable input voltages;
  • relay power-switching circuits;
  • overload and short-circuit protection;
  • fast response time;
  • ability to work at declared load power within the entire range of input voltages;
  • output power filter to suppress high frequency distortions;
  • automatic power cutoff when voltage exceeds the preset threshold;
  • subsequent automatic reactivation after voltage is restored to levels within the allowed range of operation.
