Read MoreThe Delta Electronics Sync Series DRS-24V100W1AZ is a high-efficiency 24 Vdc DIN-rail power supply engineered for industrial applications. Delivering up to 100 W of regulated DC power, this compact unit combines robust electrical performance with a slim, space-saving design ideal for high-density cabinets.
Featuring a wide 85–264 Vac input range and active power factor correction (PFC), the DRS-24V100W series ensures stable operation across global mains supplies while maintaining efficiency of up to 89%. The output voltage is adjustable to suit system requirements, and the unit supports capacitive loads up to 3000 µF, making it suitable for PLCs, industrial controllers, sensors, and actuators.
Designed for harsh industrial environments, the Sync Series offers full-power operation up to +55°C, cold start capability down to -40°C, and comprehensive protection against over-voltage, overload, short circuit, and over-temperature conditions. Select models also provide a DC OK relay contact for remote system monitoring, enhancing reliability in critical applications.
Certified to IEC/EN/UL 62368-1, UL 508, and NEC Class 2 / Limited Power Source (LPS) (model dependent), the DRS-24V100W delivers trusted Delta Electronics performance for modern industrial power systems.
