Modalis MR 30000-3C AC voltage stabilizer
The three-phase Mofalis MR 30000-3C AC voltage stabilizer is part of the Modalis product range of C series rack stabilizers.
The C series of Modalis stabilizers was designed with conservation of space and wide-spread use of 19" racks in mind. The stabilizer takes up the minimum space and fits in a standard 19" rack.
Modalis MR 30000-3C voltage stabilizer is designed for protection of home and office appliances and industrial equipment with aggregate power consumption of up to 30 kVA (that's the output capacity of a house, office or production facility). To power up induction motors (which can be found inside refrigerators, air pumps and compression pumps, and high-pressure washers), the voltage stabilizers must have a reserve capacity that's at least three times greater than the motor's own capacity.
Modalis MR 30000-3C voltage stabilizer is designed for convenient assembly and service, and its attractive apeparance is an additional advantage.
Design features:
- voltage stabilizer consists of three one-phase power units, switching unit, and 19" two-post rack;
- 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;
- compulsory 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 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 the voltage is restored to levels within the allowed range of operation;
- manual bypass (both in the power and switching units);
- 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;
- set of rollers (optional).
