Стабилизатор переменного напряжения Modalis MR 12000C

Modalis MR 12000C AC voltage stabilizer


Modalis MR 12000C single-phase AC voltage stabilizer is part of the Modalis product range of C series 19" stabilizers.

The C series of Modalis stabilizers was designed to take into account the wide-spread use of 19" equipment racks throughout the industrial, telecom and IT sectors.

Modalis MR 12000C voltage stabilizers is designed for protection of telecom equipment, computers and office appliances, industrial controllers and automatic process control systems with aggregate power consumption of up to 12 kVA. To power up induction motors, the voltage stabilizer must have a reserve capacity that's at least three times greater than the motor's own capacity. 

Modalis MR 12000C AC voltage stabilizer is designed for convenient assembly in 19" racks and lockers and one-way servicing through the front panel.



Design features:

  • 19" box with a height of 5U;
  • 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;
  • compulsary cooling procedure (built-in smart fan);
  • discrete (step-by-step) adjustment of output voltage;
  • wide range of input voltage;
  • high overload capacity;
  • thyristor power-switching circuits;
  • fast response time;
  • electronic overload and short-circuit protection feature 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 the voltage is restored to levels within the allowed range of operation;
  • manual bypass;
  • input and output power filter to suppress high frequency distortions;
  • LED indicators of operating modes and main parameters (input and output voltages, load power);
  • screw terminal for connecting power supply and load cables.
  • Voltage-free outputs can be installed in accordance with Client's changes to design specifications. Installation of voltage-free outputs is charged separately.
