Modalis IS 550 AC inverter stabilizer


IS 550 smallCompared to other types of power surge protectors, Modalis inverter stabilizer guarantees the highest level of equipment protection. Thanks to the use of double conversion technology, this surge protector boasts unique specifications and consumer properties.

This model is designed for protection of equipment with maximum wattage of 550 VA / 400 W (boiler regulators and automatic equipment of other essential consumers, TV sets, audio and video equipment, computers, fax machines, office telephone switchboards, medical equipment, precision measuring devices, etc). 

Modalis inverter stabilizer with a wattage of 550 VA / 400 W is shaped like a box with display LED, power switch and two European standard sockets on the front panel. The inverter can be mounted on either table or wall. The set also includes a power cable with European standard plug.


Design features:

  • transformless system of double voltage conversion using state-of-the art IGBT transistors with microprocessor control;
  • small weight and size compared with similar wattage devices;
  • configuration of output voltage is always a pure sine wave regardless of input voltage parameters;
  • distortions of input voltage configuration are corrected by the surge protector;
  • immediate reaction to changes in input voltage. Absence of transient phenomena in case of input voltage jumps;
  • wide range of input voltage and high precision of output regulation;
  • input capacity corrector. Regardless of the type of power demand, the surge protector always provides an active load for the power grid and doesn't distort the primary grid;
  • power demand and surge protector itself are fully electronically protected from short-circuit, grid overload, reduced input voltage, overvoltage and overheating;
  • filtration of high-frequency interference from the primary grid.
