Functions

Converts single-phase voltage to three-phase – allows connection of three-phase devices to a standard 230 V network.

Precise voltage and current control – integrated display enables fast diagnostics.

Automatic protections – prevent accidents, overheating, or electric shock risks.

Reliable cooling system – stable operation even under intensive use.

Applications

For home users: possibility to connect a three-phase compressor, welding machine, or tools in a garage or workshop.

For engineers: convenient tool for testing small three-phase equipment where a three-phase supply is not available.

For electricians: useful for installation and commissioning of three-phase systems at construction sites or locations without a three-phase input.

Industrial use: air conditioners, mixers, control machines, three-phase motors.

Pros

Enables use of three-phase equipment on a single-phase network.

Integrated protections against common electrical faults.

Real-time current and voltage indication.

Compact and reliable with effective cooling system.

Suitable for a wide range of equipment – from household appliances to industrial machinery.

Cons

Requires basic electrical knowledge for installation and connection.

Higher cost than a simple transformer, but functionality justifies the investment.
