SQ976-3F-400-500_Din-Rail Application_ AC-DC
SQ976-3F-400-500
The SQ976-3F-400-500 is a rugged 960 W single-output DIN-rail power supply designed for industrial applications requiring stability and safety. With a wide 3-phase AC input range (340–576 Vac) or high-voltage DC input (480–810 Vdc), it delivers a trimmable 24 VDC output (21.6–28.0 V). The unit achieves up to 91% efficiency, includes built-in inrush limiting, EMI filtering, and comprehensive protections against overload and overvoltage. A green LED indicates output status, and natural convection cooling supports reliable operation from –10 °C to +70 °C with power derating above 60 °C. Fully compliant with EN 62368-1, UL 60950-1, EN 55011, and CE EMC standards, it is ideal for demanding environments such as automation, controls, and instrumentation.
