We present to you the new PH-31 voltage relay for home and industrial use.

The device is designed to protect single-phase consumers from critical voltage levels in the power grid.

The unique feature of the PH-31 is its pulse power supply, which allows the relay to operate with "non-standard" voltage sources, such as single-phase generators of any type, inverters, and UPS systems with a modified sine wave, among others.

Advantages:

• operates both from the power grid and a generator
• compact size (only 1 module)
• non-flammable housing material

Application area:

• domestic use: protection for the entire home or individual devices such as refrigerators, air conditioners, heaters, computers, etc
• industrial use: as part of a control and switching panel; as a component of equipment such as industrial refrigerators, machines, etc

Key features:

• has a pulse power supply, allowing it to operate with non-sinusoidal input voltage (generators, inverters, voltage converters, etc.)
• easy and simple setup – setting just 3 parameters will provide protection for your devices against the main electrical network failures
