COSEL Adds Open Frame Power Supplies in LHA Series

In conducted noise tests, the LHA10F and LHA15F comply with FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B, and EN55032-B.

Cosel has added two open frame compact power supplies for industrial applications to its LHA series.

COSEL Power SuppliesBenefiting 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 can operate in a wide temperature range from -10 to +70 degrees C. The power supplies are UL/EN62368-1 certified.

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 of up to 84.5% at 230VAC and rated load.

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. They offer low leakage currents, the LHA10F has 150-microampere max and the LHA15F has 100-microampere max at 240VAC/60Hz.

Designed for use in demanding applications where space is often limited, the LHA10F measures just 50 X 21.5 X 62.5mm (1.97 X 0.85 X 2.46 inches) and weighs 45g max. The LHA15F measures 50 X 21.5 X 73.5mm (1.97 X 0.85 X 2.89 inches) and weighs 60g max.

Additional options are available for specific applications, option-C for a conformal coating for improved moisture resistance, option-J4 for input and output EP connectors, option -S with chassis, option -SN with chassis and cover, and option -Y for an output voltage potentiometer.

The LHA10F and LHA15F complement Cosel’s extensive range of products for high demanding industrial applications requiring efficient power from 10W up to 300W.

The power supplies offer an ideal solution for the maintenance of equipment using the previous COSEL LDA series.
