120W DIN-Rail Power Supplies with Lifetime over 131,000 Hours

April 22, 2018 by Paul Shepard

PULS has added the CP5.241 a 120W (24V / 5A) DIN-rail power supply that features an extra-long lifetime of more than 131,000 hours, an efficiency of 94.3% and a reduced size - width 32mm and depth only 102mm.

These DIN-rail power supplies have an extra-long lifetime of over 131,000 hours (AC 230V, full load, +40°C). The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131,400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.

High efficiency is achieved using an LLC resonant converter. This advanced converter topology is atypical for a 120W power supply, but very efficient. The CP5.241 has an efficiency of 94.3%, resulting in only 7.3W power losses at AC 230V and full load.

The Dimension CP-Series are cost optimized power supplies without compromising quality, reliability and performance. The CP-Series is part of the DIMENSION power supply family.

The CP5.241 power supplies come with three connection terminal options: screw, spring-clamp or push-in terminals, which are optimized for automated wiring.

The CP5.241-C1 is equipped with conformal coated pc-boards preferred for the use in harsh environments and the CP4.242 features an enhanced dc input voltage range.

The most outstanding features of these units are the small size, the high efficiency, the electronic inrush current limitation, active PFC and the wide operational temperature range. The devices have a power reserve of 20% included, which may even be used continuously at temperatures up to +45°C. Additionally, they can deliver 3 times the nominal output current for 12ms which helps to trip fuses on faulty output branches.

High immunity to transients and power surges as well as low electromagnetic emission, a DC-OK signal contact for remote monitoring, and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
