Description

The PULS CP20.241‑S1 is a high‑performance 480 W DIN rail power supply providing an adjustable 24–28 Vdc, 20 A output with 20% Power Boost, active PFC, and spring‑clamp terminals in a slim 48 mm housing. Its wide AC/DC input range, very high efficiency, and DC‑OK signaling make it ideal for space‑constrained industrial control panels and 24 Vdc automation systems.​

Key electrical features

  • 24 Vdc nominal output adjustable from 24–28 Vdc, delivering 20 A at 24 V and 17.1 A at 28 V for flexible load matching.​

  • 480 W continuous output power with 20% Power Boost for starting high inrush loads such as motors, contactors, and capacitive loads.​

  • Very low output ripple and noise (max. 50 mVpp) to support sensitive PLCs, sensors, and communication devices.​

Input and protection

  • Wide AC input range of 100–240 Vac (‑15% / +10%) and DC input range of 110–150 Vdc (±20%), enabling global use and DC backup concepts.​

  • Active power factor correction with power factor up to 0.98 and active inrush current limitation (10 A / 4.5 A typical) to reduce upstream loading and breaker stress.​

  • Recommended external input fuse of B‑10 A or C‑10 A simplifies panel protection design.​

Mechanical and installation details

  • Compact metal housing only 48 x 124 x 127 mm to save DIN rail space in crowded cabinets.​

  • DIN rail mounting with spring‑clamp terminals for fast, vibration‑resistant wiring in industrial environments.​

  • Operating temperature range from ‑25 °C to +70 °C with derating of 12 W/°C above 60 °C, allowing full 480 W output up to 60 °C.​

Efficiency, losses, and diagnostics

  • Typical efficiency of 95.6% reduces heat dissipation to about 22.1 W at full load, easing cooling requirements and improving system reliability.​

  • MTBF of about 590,000 h at 40 °C (SN 29500) supports long life in 24/7 industrial service.​

  • Integrated DC‑OK relay contact provides status feedback to PLCs or monitoring systems for proactive maintenance and fault detection.
