Cosel has launched a series of open frame compact AC-DC converters that are EN62477-1 OVC III certified for demanding industrial applications.
Cosel has launched a series of open frame compact AC-DC converters that are EN62477-1 OVC III certified for demanding industrial applications.

The OVC III AC-DC converters include inrush current protection, 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 direction, though depending on the ambient temperature and environment, a derating may apply.

In conducted noise tests, the LHA150F and LHA300F comply with FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B, and EN55032-B. For further improved noise performance COSEL offers IEC61000-3-2 (Class A) compliant harmonic attenuation filters type EAC-03-472 for the LHA150F and EAC-06-472 for the LHA300F.  The units have a 3,000VAC input to output isolation voltage, 2,000VAC input to ground and 500VAC output to ground.

Designed for use in demanding applications where space is often limited, the LHA150F measures 75 X 27 X 160mm (2.95 X 1.07 X 6.30 inches) and weighs 320g. The LHA300F measures 84 X 37 X 180mm (3.31 X 1.46 X 7.09 inches) and weighs in at 580g.

Additional options are available for specific applications, option-C for a conformal coating for improved moisture resistance, option-G for a lower leakage current (0.15mA max.), option-J4 for input and output EP connectors, and option-Y for an output voltage potentiometer.

The LHA150F and LHA300F are suitable for a wide range of applications including measurement and analysis equipment, machine tools and industrial robots, display equipment and semiconductor manufacturing equipment. They comply with the RoHS directive and are CE marked in accordance with the Low Voltage Directive.
