PULS
$605.00
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.
