Automatic phase switch electronic PEF-305 NTPEF5325

Stable power supply for home and industry

The PEF-305 automatic phase switch is an intelligent solution providing uninterrupted power supply to devices sensitive to voltage fluctuations. The device automatically monitors the voltage in a three-phase network and, in the event of a drop in one of the phases, instantly – within 150 milliseconds – switches the load to the phase with the best parameters. This is ideal protection for homes, workshops, server rooms and all types of equipment requiring a stable power supply.

Intelligent protection and reliability

PEF-305 uses microprocessor control, which guarantees precise operation and long service life. The device has a built-in priority function for phase L1 – if its parameters return to normal, it switches the load to it, ensuring optimal stability. Additionally, PEF-305 protects against overload and has an IP20 protection class and safety class II, which increases safety.

Easy installation and wide application

The switch is extremely easy to install thanks to its compact housing designed for mounting on a standard 35 mm DIN rail. The device is dedicated to industrial and home installations and is also used in facilities such as gas stations or medical facilities. The PEF-305 switch is an investment in peace of mind and protection of your equipment.

• Automatic phase switching: Reaction time of up to 150 ms ensures power continuity even with sudden voltage drops.
• Phase L1 priority: Ensures return to the preferred phase after network parameters stabilize.
• Microprocessor control: Guarantees precise operation and long device life.
• Overload protection: Protects the circuit from damage caused by excessive load.
• Easy installation: Compact housing and DIN rail mounting simplify installation.
• Wide application: Ideal for homes, workshops, server rooms and other facilities requiring a stable power supply.

Using PEF-305 allows you to avoid downtime caused by voltage fluctuations, thereby minimizing the risk of damage to connected devices. This is a solid solution for anyone who values reliable and safe power supply.
