To meet the demand in this broad market, MEAN WELL and OLFER Electronics announce the new DIN rail series: the DRS-240 and DRS-480 intelligent safety power supplies.
The most attractive feature of the DRS-240/480 is its multifunctional integration, which includes an AC/DC power supply, battery charger, DC-UPS, and communication monitor in a compact form factor. Other key features include a 90-305V AC input applicable worldwide, compliance with safety control standards and alarm signals, and automatic power balancing with load priority (the battery will be charged with excess power). Furthermore, the devices have a built-in MODBus communication interface, and charging parameters can be adjusted via the SBP-001. The 2-stage/3-stage charging curve and charging current setting (20%-100%) can also be manually adjusted via the front panel. The flexible charging parameters allow the DRS-240/480 to be compatible with a variety of lead-acid and lithium batteries. These integrations make the DRS-240/480 one of the most comprehensive DIN rail power supplies for fire and security systems. This series provides the ideal solution for fire safety systems, including emergency communication equipment, emergency fire lighting, access control systems, central monitoring systems, and more.
