Cosel today announced the addition to its LHA series of two compact open frame power supplies for demanding industrial applications. Benefiting from the latest power switching technologies, the LHA10F and LHA15F are 15% smaller and offer 50% lower leakage current 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.
With increasing levels of system integration, factory automation requires more compact power supplies, capable of working with the highest levels of safety in various environments. The LHA10F and LHA15F have been designed to provide robust insulation 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 input voltage range of 100-240VAC (50/60Hz) safety standards.
The power supplies are available in five output voltages, 3,3V, 5V, 12V, 15V, 24V with their respective currents. In both versions, the 3,3V output voltage can be adjusted in the range of 2,85V to 3,63V, the rest of the voltages being fixed at the factory.
The LHA10F and LHA15F benefit from an optimized switching topology developed for the higher power LHA series, and have an efficiency of up to 84,5% at 230VAC and nominal load.
Power supplies include inrush current limiting, overcurrent protection with automatic recovery when default value is removed, and overvoltage protection.
The units are designed to operate between -10 and +70 degrees C and can be mounted in any orientation, although depending on the ambient temperature and environment, 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 standards.
The units have an isolation voltage of 3.000 VAC input to output, 2.000 VAC input to ground, and 500 VAC output to ground. They offer low leakage currents, the LHA10F is 150 microamps maximum and the LHA15F is 100 microamps maximum at 240VAC/60Hz.
Designed for use in demanding applications where space is often at a premium, the LHA10F measures just 50 X 21,5 X 62,5mm (1,97 X 0,85 X 2,46 inches) and weighs a maximum of 45g . The LHA15F measures 50 X 21,5 X 73,5 mm (1,97 X 0,85 X 2,89 inches) and weighs a maximum of 60 g.
Additional options are available for specific applications, option-C for a protective coating to improve moisture resistance, option-J4 for input and output EP connectors, option -S with chassis, option -SN with chassis and cover, and -Y option for an output voltage potentiometer.
The LHA10F and LHA15F complement the wide range of Cosel products for highly demanding industrial applications that require efficient power from 10W to 300W. These power supplies offer an ideal solution for the maintenance of equipment that uses the previous series of COSEL LDA.
The LHA10F and LHA15F are suitable for a wide range of applications, such as measurement and analysis equipment, industrial machine tools and robots, display equipment, and semiconductor manufacturing equipment. They are RoHS and Low Voltage compliant and carry the CE and UKCA mark.
