AC voltage stabilizer Modalis MR 2000SPT



Modalis MR 2000SPT AC voltage stabilizer 


Modalis MR 2000SPT single-phase AC voltage stabilizer is part of the Modalis product range of Thermo-Sim (ST, SPT) stabilizers.

Modalis MR 2000SPT voltage stabilizer is designed for protection of different types of energy-dependent boiler equipment with aggregate power consumption of no more than 2 kVA.

Modalis MR 2000SPT voltage stabilizer is designed as a wall-mounted unit with indicator panel and automatic power switch on the front panel, and  groundbed on the bottom panel. The screw terminal for connecting power supply and load cables is located under removable cover.



Design features:

  • wall-mount enclosure (mounting bracket included);
  • toroidal power autotransformer;
  • quiet operation;
  • increased reliability and durability;
  • 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;
  • programmable cooling system;
  • discrete (step-by-step) adjustment of output voltage;
  • wide range of input voltage;
  • high overload capacity;
  • TRIAC power circuits;
  • fast response time;
  • electronic overload and short-circuit protection featuring automatic disconnection and subsequent nonrecurrent automatic reactivation;
  • 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 to connect the load and plug into the power circuit.
