The MP347A from Thomas Research Products is an AC/DC converter designed for reliable power delivery. It operates with an input voltage of 347VAC at 60Hz and provides a regulated 24VDC output with a nominal current of 100mA.
Constructed with high-impact UL 94-5V plastic, this power pack is built for durability. Its dimensions are 3.69" H x 2.33" W x 1.36" D (93.73mm H x 59.18mm W x 34.54mm D). The unit is designed for indoor use only, with an operating temperature range of 32°F to 104°F (0°C to 40°C) and a relative humidity range of 0% to 95% (non-condensing).
Installation is versatile, as it can be mounted inside or outside a junction box. It complies with requirements for use in a plenum area and is plenum rated for external junction box mounting. The MP347A includes a self-contained transformer and relay, and a companion auxiliary relay device is available. It is UL and cUL listed, ensuring compliance with safety standards.
This power pack is suitable for applications requiring a stable 24VDC power source. It has a load rating of 15A for both 347VAC incandescent and ballast loads. Note that it is not recommended to power more than 3 devices from a single power pack, and 18-22AWG low voltage wire is recommended.
The MP347A accepts 85-264VAC or 347VAC @ 60Hz.
The output is 24VDC at 100mA.
