SNR electronic voltage stabilizers are intended for maintaining stable supply voltage of residential and industrial loads of 220 V/3 x 220 V, 50 Hz at power fluctuations within wide range of value and period of time. Electronic voltage regulators are applied for stabilizing voltage when working with domestic and industrial equipment, commercial units, communication devices as well as complex supply systems of cottages, flats and offices. Single-phase electronic voltage regulators SNR1 correspond to the requirements of EN 55014-1, EN 55014-2, EN 60335-1, EN 61000-3-2. Electronic controls of gas heating equipment requires a stabilized supply voltage. The innovative voltage stabilizer of BOILER series was designed as a result of thorough investigation of power supply parameters for gas boilers. Now, gas heating systems have reliable protection against failures. Strict correspondence of the rated power due to using high-power transformers and power electronic switches.
