New thin open frame power supplies for demanding industrial applications

     Cosel Co, Ltd has added two open-frame compact power supplies to its LHA range for demanding industrial applications. They are suitable for a wide range of applications and can operate in a wide temperature range from -10C to +70C. The power supply is UL/EN62368-1 certified. Thanks to the latest power switch technology, the LHA10F and LHA15F are 15 percent smaller in size and have a 50 percent lower leakage current than conventional products on the market.

     As the level of system integration increases, factory automation requires more compact power supplies to work with the highest level of safety in a variety of environments. The LHA10F and LHA15F are designed to provide strong isolation levels and low leakage current. For worldwide applications, the single-phase input voltage range is 85VAC to 264VAC, conforming to the safety standard input voltage range of 100-240VAC (50/60Hz).

     In these versions, the 3.3V output voltage can be adjusted from 2.85V to 3.63V, and all other voltages are factory fixed. The power supply provides five output voltages, 3.3V, 5V, 12V, 15V, 24V, and current.they benefit from an optimized switch topology design for the higher power LHA series with an efficiency of up to 84.5% at 230VAC and rated load.

     The device is designed to operate at -10 ° C to +70 ° C and can be installed in any direction, but there may be derating depending on the ambient temperature and environment.in the noise tests conducted, the LHA10F and LHA15F met the requirements of FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B and EN55032-B.

     The device has a 3000VAC input/output isolation voltage, 2000VAC input to ground and 500VAC output to ground. Low leakage current, maximum µ a at 240VAC/60Hz for LHA10F and 100 μ A for LHA15F.

     Designed for demanding applications where space is limited, the LHA10F measures only 50mm x 21.5mm x 62.5mm(1.97 "x 0.85" x 2.46 ") and has a maximum weight of 45g. The LHA15F measures 50mm x 21.5mm x 73.5mm(1.97 "x 0.85" x 2.89 ") and has a maximum weight of 60g.

     They comply with RoHS and low voltage directives and carry the CE mark and UKCA. And they are suitable for a variety of applications, including measuring and analytical equipment, machine tools and industrial robots, display equipment and semiconductor manufacturing equipment.
