MEAN WELL has invested in DIN-rail power supplies in 2000 and has now owned 10-960W power supplies and related accessory modules. The product line is quite complete and ranks among the top in the DIN-rail standard power supply market. However, with the development of urbanization, from a small building to an entire smart city, in order to improve public safety, countries in Europe and the United States have formulated safety regulations for safety control and fire protection systems (EN54-4/ UL2524/ GB17945). MEAN WELL has launched a new 240W/480W all-in-one digital intelligent security control power supply ~DRS-240/480 series.

The biggest feature of DRS-240/ 480 is the multi-functional integrated design of DC voltage power supply, battery charging, DC-UPS, and communication monitoring in a compact size. Other features are: 90 ~ 305Vac input applicable to all parts of the world, in line with safety control regulations and alarm signals , The intelligent mechanism of giving priority to power supply to the load (remaining power to charge the battery), built-in MODBus communication interface, can be used with SBP-001 programmer to intelligently adjust the internal charging parameters, or adjust the 2-stage/3-stage charging and Adjustable 20-100% charging current, suitable for lead-acid or lithium batteries of different capacities, etc. It is a rare rail-type composite function intelligent security control power supply on the market, which can provide emergency communication equipment with continuous information, The best solution for fire emergency lighting, access alarm system, central monitoring, etc.
