Power supply with integrated device protection
10 April 2025
THE TRIO Power power supply with integrated electronic circuit breaker from Phoenix Contact is now also available as a three-phase version.

The third generation of Trio Power power supplies continues to set the new standard in machine building. The power supplies are compact, robust, reliable, and impress with their easy handling. The new three-phase power supplies with integrated multi-channel device protection feature a space-saving design and are now also available up to a 40 A nominal output current.
The power supply units also feature particularly easy handling: Push-in connection technology allows for quick and tool-free installation. Integrated marking fields can be used for easy EID and circuit marking. Due to an intuitive commissioning concept, the devices are quickly ready for use. The mechanical lock of the potentiometers ensures that the devices are also tamper-proof.
Furthermore, the power supplies feature smart diagnostic options: multicolour LEDs and a collective relay contact signal all relevant states. The remote reset function enables the output channels to be reset via the digital input. IO-Link communication facilitates detailed diagnostics and parameterisation. The dynamic boost (150%/5 s) also enables difficult loads to be started. Intelligent self-monitoring and integrated load management ensure high system availability.
