The QUINT4-PS/1AC/12DC/7.5/PT (Item No: 2904607) is engineered to deliver precise 12 V DC output with a steady 7.5 A current, making it suitable for powering relays, sensors, and control modules. Its wide input voltage range of 110 V DC to 250 V DC, with -20% to +40% tolerance, ensures stable operation even in fluctuating supply conditions. The unit supports a typical inrush current of 11.4 A at 25°C and maintains efficiency up to 91.5% at 120 V AC, which translates into reduced energy loss and long-term cost savings for factory operators.
Built for industrial reliability, this Phoenix Contact power supply features short-circuit protection, DIN rail mounting, and IP20-rated housing to suit standard panel environments. It offers 4 kV AC insulation between input and output for enhanced safety, and keeps residual ripple under 35 mVPP to ensure noise-free power delivery to critical devices. Designed for extended life cycles, it performs consistently within -25°C to +70°C with thermal derating above 60°C at 2.5% per K. With power loss under 8.1 W at full load, it is both energy efficient and dependable under continuous use.
Maintenance engineers prefer the QUINT4-PS/1AC/12DC/7.5/PT (Item No: 2904607) for distributed I/O stations, PLCs, SCADA terminals, and 12V instrumentation in process plants, utility panels, and OEM machines. It supports long wiring runs without voltage dips and ensures reliable starts for downstream loads.
