Modalis MR 16000C AC voltage stabilizer


Modalis MR 16000C one-phase AC voltage stabilizer is part of the Modalis produc range of C series rackmount Modalis stabilizers.

The C series of Modalis stabilizers was designed to take into account the wide-spread use of 19" equipment racks. Consequently, the stabilizer has a minimum surface area and fits into all standard 19" racks. 

Modalis MR 16000C voltage stabilizer is designed for protection of home and office appliances and industrial equipment with aggregate power consumption of up to 16 kVA. To power up induction motors (found in refrigerators, air pumps, compressor pumps, and high-pressure washers), the voltage stabilizer must have a reserve capacity that's at least three times greater than the motor's own capacity. 

Modalis MR 16000C voltage stabilizer is manufactured with the use of Double Coil technology (when the same transformer coil works both to increase and decrease the voltage). 

Modalis MR 16000C voltage stabilizer is designed for convenient assembly and servicing, and its attractive appearance is an additional advantage. 



Design features:

    • toroidal power autotransformer;
    • double load protection from critically high input voltages;
    • automatic disconnection of autotransformer in case of input voltage surge over 300 V with subsequent automatic reactivation once a safe voltage has been restored;
    • compulsory cooling procedure (built-in smart fan);
    • discrete (step-by-step) adjustment of output voltage;
    • wide range of input voltages;
    • high overload capacity;
    • thyristor power switches;
    • fast response time;
    • electronic short-circuit and overload 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;
    • manual bypass (both in the power unit and the switching unit);
    • input and output power filter to suppress high frequency distortions;
    • LED indicators of operating modes and main parameters (input and output voltage, load power);
    • screw terminal for connecting power supply and load cables.
