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.
