Power Supply for Building Automation: Supply and Charge Via USB
February 22, 2024
The Step Power power supplies from Phoenix Contact are tailored to the needs of modern building automation. They supply smart meter gateways, Raspberry Pis, and other smart home components via the USB port. In addition, they can be used for the fast charging of mobile end devices and other 5 V loads.
The power supply unit has a USB-A or USB-C port for up to 15 W. Using it as a USB charger provides more space in the distribution board, control cabinet, or flat control panels due to the particularly narrow overall width of just 18 mm (1 HP). This completely eliminates the need for the classic combination of an electrical outlet with an overall width of 45 mm (2.5 HP) and a USB power supply unit. The integrated cable groove with strain relief in the housing of the power supply enables the USB cable to be routed easily under the cover of the distribution board, if required – thus simplifying handling.
With low no-load losses of <0.1 W and a high degree of efficiency, the Step Power power supplies offer optimum energy efficiency in buildings. Due to effective energy savings achieved as a result of maximum efficiency in no-load operation and partial-load operation, the power supplies meet the stringent requirements of the efficiency standards of the Ecodesign Directive. The large wide range input of 85 V AC … 264 V AC and the temperature range of -25 to +70°C also enable worldwide use in almost all ambient conditions.

Power Supplies for Extreme Ambient Conditions from Phoenix Contact
The third generation of power supplies sets a new standard in machine building. The power supplies are compact, robust, reliable, and impress with their 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 multicolor 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.
