Switch Mode Power Supply ARF 130O (Open Frame)
With compact dimensions of only 80 mm × 60 mm (2×3), the ARF130 series is one of Arch Electronics' most popular fanless switch-mode power supply series. The power supplies deliver up to 125 watts without cooling, feature a wide input range of 90 V to 264 V (AC), and operate in ambient temperatures from -30 °C to 80 °C.
Additional features of the ARF130 series include low no-load power consumption, high energy efficiency, active power factor correction (PFC), and an isolation voltage of 4000 volts. Safety certification according to UL / IEC / EN 62368-1 ensures short development and design cycles.
The ARF130 series power supplies are available with output voltages of 12 V, 24 V, and 48 V, and can be supplied with or without a housing (ARF130E, ARF130O) or in a U-channel version (ARF130U).

External Power Supplies (Plug-in and Desktop Power Supplies)
Find practical answers to frequently asked questions about our external plug-in and desktop power supplies for industrial, medical, and IT applications. These articles support you with selecting the appropriate model, navigating country-specific mains plug options, and ensuring safe commissioning and troubleshooting.
Worauf muss ich bei der Auswahl eines passenden externen Netzteils achten?
For an external power supply unit (e.g. a desktop power supply) to operate safely, four criteria must match your device: voltage, current, polarity, and connector dimensions. You will usually find the required ratings on your device’s rating plate (typically under "Input") or on your previous power supply under "Output".
- Voltage (volts / V) – must match exactly: The output voltage of the power supply unit must match your device's input voltage precisely. Excessive voltage can permanently damage the electronics; insufficient voltage will cause the device not to start or to run unstably.
- Current (amperes / A) – may be higher: The power supply unit must supply at least the current required by the device. A higher ampere or wattage rating on the power supply poses no risk, as the device only draws the current it actually requires.
- Polarity – must match: Check the polarity symbol on the device. DC barrel connectors are usually centre-positive (positive pole inside). The replacement power supply must have identical polarity.
- Connector dimensions (DC barrel connector): The connector must fit securely and smoothly into the socket. Common dimensions specify the outer and inner diameters (e.g. 5.5 × 2.1 mm or 5.5 × 2.5 mm). If socket dimensions are non-standard or unclear, universal power supplies with an adapter set can help.
