Features:

High efficiency: Using high efficiency switching power supply technology, the efficiency can reach more than 90%, which can save energy.

High reliability: The use of high-quality components and advanced design technology to ensure stable and reliable product operation.

Low ripple: Low output ripple and noise, providing a stable power supply for sensitive equipment.

Protection mechanism: Provides overload protection and short circuit protection, which can automatically shut down in the case of overload or short circuit to protect the safety of the equipment.

Flexibility and scalability: The REF542plus feeder protection and measurement unit integrates protection, control, measurement, communication and monitoring functions in one unit, which can be used as feeder protection, transformer protection, motor protection and control, and can also be used as a separate control device.

Supports a variety of communication protocols, including IEC61850.

Functions:

The REF542PLUS is part of ABB’s REF542 series, designed for the digital control and protection of medium voltage switchgear. With or without a back office system, the REF542plus is the perfect solution for medium voltage switchgear. It integrates protection, control, measurement, communication, and monitoring functions in a programmable environment, enabling REF542plus to achieve almost all secondary solutions, even solutions that cannot be achieved by traditional methods.
