New high-efficiency convection cooled 500-W power supplies offer reliability benefits

July 03, 2012 // By Paul Buckley
PULS UK has launched new high-efficiency 24V-20A and 48V-10A units. The CPS20 (241 and 481) use new topology to offer customers high-quality and reliability at a competitive price.

The CPS20s deliver 94% efficiency and are packaged to take up only 65mm on the DIN-rail.  PULS has ensured low losses even at low input voltages and low loads and this is expected to become the industry benchmark for all 500 watt power supplies. New features make the CPS20s ideal for harsh environments, combining conformal coated variants with high-efficiency and reliability.

Other features include screw terminals - often favoured by engineers - negligible inrush current, allowing the use of smaller wires and fuses, a Mean Time Between Failure (MTBF) of 537,000 hours, life expectancy of 168,000 hours and PULS’s Bonus Power system delivering 20% current reserves to aid motor or inductive load start-up.


The CPS20.241 is available ex-stock from PULS UK.  The 48 V version CPS20.481, is expected in September 2012.
