PULS, the specialist for high reliability DIN-Rail power supplies, has launched a breakthrough 24V/10A DIN-Rail power supply, CP10, which sets a new industry benchmark in innovative power supply technology and sophisticated thermal design. This is the first time that a DIN-Rail power supply in this power class with a single-phase global input and active PFC has achieved an efficiency of 95%. The subsequent low level of heat generation has enables a design which has reduced the width required on the DIN-Rail to only 39mm.
Compact and rugged DIN-Rail supply for harsh environments
John Tyrrell, Managing Director of PULS UK commented, “The CP10 is a full featured supply which delivers maximum performance from -25°C to +60°C without derating. Our innovative PULS HiccupPLUS power management delivers 20% extra peak power when needed and at the same time protects loads and wiring. With an industry leading performance in this power class, our customers get the benefit of high performance in a compact and robust package”.
The CP10’s active input inrush current limiter ensures no potentially damaging surges of inrush current and its DC-OK signal monitors the output voltage. A new remote on/off feature makes it simple and convenient to remotely switch the power supply off for energy conservation rather than the traditional panel-mounted power switch.
Weighing only 600g, these compact and rugged supplies are ideally suited for applications in hostile environments where they will be subject to shock and vibration such as found in vehicles and wind power installations. For the process industry the CP10 is approved according to ATEX/IECEx standards at no extra charge. 12V and 48V versions will follow soon to lay the foundation for a new family of products for multiple applications. Samples are available now from stock.
PULS Powers Mecca Clock Tower
High efficiency power supplies drive 2 million LEDs
When night falls in Mecca the green dials of the largest clock tower in the world are still clearly visible at a distance of over 10 miles. Two million LEDs – and around 1000 PULS power supplies illuminate the four clocks mounted on each side of this colossal tower at a height of 400 metres. During the daytime the clock dials are white, but at night they are illuminated bright green. The hands are black during the day and brilliant white at night. The tower has been designed and tested to provide a service life of 100 years during which it will have to withstand extreme weather conditions and hurricane-force wind.
The 1000 PULS Dimension XT series, 48V / 20A power units deliver the one million watts required to illuminate the LEDs and consequently form the core of the electronic lighting system; if they fail the clock faces remain dark.
The 600 m Mecca Tower could be prone to a lightning strike. PULS tested its installation using a supply of 500kV / 4000A with both air discharge and multiple discharges to the power supply input. The robustness of the Dimension series successfully protected the units from damage and since its installation in 2012, the tower has shone every night – reliably showing millions of people visiting the city the accurate time, day and night.
