Product Performance

The wide voltage input range can adapt to different industrial power grids around the world, stably output within the range of voltage fluctuation and frequency deviation, without additional adaptation devices.

Multi-voltage level output design can simultaneously supply power to the chassis backplane logic circuit, external 24V sensors and small actuators, simplifying system wiring.

Built-in multiple electrical protection mechanisms, automatically cut off output when abnormalities are detected, preventing fault spread to other control modules and ensuring system safety.

Fanless natural convection cooling design reduces mechanical wear and fault points, adapting to harsh industrial environments such as high dust and high vibration, with long service life.

Exclusive power slot installation does not occupy control slot resources, and can be flexibly matched with various I/O and communication modules, improving chassis space utilization.

High output voltage accuracy and low ripple noise provide stable power supply for high-speed control modules and analog modules, ensuring control accuracy and data correctness.

Industrial-grade protection and wide temperature adaptability can operate stably for a long time under 0-60℃ environment, meeting the installation needs of various industrial sites.

Deeply compatible with ControlLogix series products, seamless integration without additional configuration, reducing system integration cost and debugging cycle.
