Factory automation requires more compact power supplies able to work with the highest levels of safety in a variety of environments.
Cosel Co has announced the addition of two open frame compact power supplies for demanding industrial applications to its LHA series. Benefiting from the latest power switching technologies, the LHA10F and LHA15F are 15% smaller and offer a leakage current 50% lower than conventional products on the market. Designed for use in a wide range of applications, the LHA10F and LHA15F are able to operate in a wide temperature range from -10 to 70 degrees C. The power supplies are UL/EN62368-1 certified.
With the increased levels of systems integration, factory automation requires more compact power supplies able to work with the highest levels of safety in a variety of environments. The LHA10F and LHA15F have been designed to provide robust isolation levels and very low leakage currents.
Designed for worldwide applications, the LHA10F and LHA15F have an input voltage range of 85VAC to 264VAC single phase, and conform to the safety standards input voltage range of 100-240VAC (50/60Hz).
The power supplies are available in five output voltages, 3.3V, 5V, 12V, 15V, 24V with respective currents. On both versions, the 3.3V output voltage can be adjusted in the range of 2.85V to 3.63V, all other voltages being factory fixed.
The LHA10F and LHA15F benefit from an optimized switching topology developed for higher power LHA series, and have an efficiency up to 84.5% at 230VAC and rated load.
The power supplies include inrush current limitation, over-current protection with automatic recovery when the default is removed, and over-voltage protection.
The units are designed to operate from -10 to 70 degrees C and they can be mounted in any orientation, though depending on the ambient temperature and environment, a derating may apply.
In conducted noise tests, the LHA10F and LHA15F comply with FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B, and EN55032-B. The units have a 3,000VAC input to output isolation voltage, 2,000VAC input to ground and 500VAC output to ground.
