Inverter voltage stabilizer KiloHertz U 1-5

The KiloHertz U 1-5 inverter voltage stabilizer is a double-conversion inverter voltage stabilizer consisting of a power stage based on a modern IGBT module of the latest generation.

The KiloHertz U 1-5 series stabilizer is characterized by the following key features:

• the highest accuracy of output voltage stabilization (±0.5%);

• the latest STmicroelectronics processor of the STM32G4 series with integrated analog elements is used;

• the power stage is made on the basis of an intelligent power IGBT module with integrated drivers and a protection system;

• transformerless power section circuit;

• the double-conversion stabilizer generates voltage waveform practically independent of the input network voltage waveform;

• low own power consumption at idle, use of highly efficient quasi-pulse power supply;

• in version U 1-5 - smooth intelligent control of forced cooling fans allows to achieve minimal energy costs for cooling, increase the service life of fans and reduce acoustic noise;

• adjustment of the shutdown threshold based on the minimum input voltage of 50-135 V;

• the ability to adjust the value of the specified output voltage within 200-230 V;

• high-precision RMS measurement of input voltage;

• the ability to operate from gasoline/diesel generator sets;

• power supply protection system cascade from overheating;

• the presence of an output choke to muffle high-frequency interference;

• the presence of an output varistor to protect against impulse overvoltages in emergency modes;

• automatic shutdown of the consumer load when a dangerous undervoltage or overvoltage appears at the input of the stabilizer
