DRS Series – DIN Rail Power Supplies

As a response to the rapid development of complex building architectures, the governments of Europe, the USA, and China created safety regulations for security and fire systems (EN54-4/UL2524/GB17945). MEAN WELL's DRS-240 and DRS-480 series are all-in-one, DIN rail type intelligent security power supplies to satisfy this vast market.

The most attractive feature of DRS-240 and DRS-480 is the multi-functional integration, which includes AC-DC power supply, battery charger, DC-UPS, and communication monitor in a single compact package. They also feature 90 V_AC to 305 V_AC input applicable to all parts of the world, compliance with safety control regulations and alarm signals, and automatic load priority power balancing (the battery will be charged with excess power). The product has a built-in Modbus communication interface, and charging parameters can be adjusted via SBP-001. The 2-stage/3-stage charging curve and charging current setting (20% to 100%) can also be adjusted manually through the front panel. The charging parameter flexibility allows the DRS-240 and DRS-480 to be suitable for various lead-acid and lithium batteries. These integrations enable the DRS-240 and DRS-480 to become one of the most complete DIN rail PSU for security and fire systems. The DRS-240 and DRS-480 provide the best solution for fire safety systems such as emergency communication equipment, fire emergency lighting, access control systems, central monitoring systems, and more.
