Product description
  • The DRS-240 is a 240W AC/DC safety power supply series for DIN rail mounting. In addition to the primary output, it features an additional charging circuit that automatically adjusts the charging current to match the primary output current. The DRS-240 operates within a universal input range of 90 VAC to 305 VAC and supports output systems with nominal voltages of 12 VDC, 24 VDC, 36 VDC and 48 VDC. With a high efficiency of up to 92%, it can be operated via convection cooling at ambient temperatures ranging from -30°C to 70°C. In addition to protective functions such as overload protection, overvoltage protection, battery undervoltage protection and reverse polarity protection for the battery, the DRS-240 also features relay contacts and LED indicator alarm signals for AC failure, battery undervoltage, charging circuit failure and DC OK, to ensure easy integration into security systems that comply with local alarm regulations.
