Power supplies for extreme ambient conditions

(See Phoenix Contact at MachineBuilding.Live, 2 October 2024, on stand 16)

The third generation of power supplies are compact, robust, reliable and offer easy handling. With the protective-coated PCB, the new power supply ensures high system availability, even under extreme ambient conditions. The coating protects against dust, corrosive gases, and humidity. Failures due to creepage currents and electrochemical migration caused by corrosion are also prevented.

The new Trio Power power supplies save space due to their narrow overall width and capability of being mounted directly side by side. The low overall depth enables installation in 125 mm small housings. The power supply units also enable 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. The multicolour LEDs and a collective relay contact are used to signal all relevant states, such as DC OK, overload, and short circuit.

The dynamic boost (150 percent/5 seconds) also enables difficult loads to be started. With the powerful output characteristic curve, even capacitive loads up to 960 W output power in 1 AC and 3 AC can be charged without any problems.
