Industrial 05701-A-0441 Rack Mount Power Supply

05701-A-0441 is a 50-watt Switched-Mode AC-to-DC power supply subunit designed for the System 57 rack architecture from Sieger/Honeywell. This 1U-high, half-width module mounts in a 19-inch rack as a second sub-unit to upgrade a basic 16‑channel PSU when more than 100 W of total power is required, delivering an additional 24 V DC output. The subunit accepts rear AC input via a three-core cable and provides a nominal 24 V DC output with regulation within ±10%, accompanied by overload protection with automatic recovery. When used with the base 16‑way PSU and the accompanying 50 W module, total available power can reach up to 200 W for the System 57 rack, furnishing headroom for additional control cards and field devices in industrial safety cabinets designed to monitor and interface with fire-detection systems. The part is part of the System 57 family and is commonly paired with the 05701-A-0440 power module to achieve the expanded power configuration.
