Cosel adds 10W and 15W models to low profile open frame power supplies
Additional 10 and 15W units have been added to Cosel’s low profile open frame power supplies for demanding industrial applications.
The two open frame compact power supplies have been added to the LHA series. The LHA10F and LHA15F are 15 per cent smaller and offer a leakage current 50 per cent lower than conventional products on the market, said Cosel. The two power supplies are designed for use in a wide range of applications and operating across 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 to meet increased levels of system integration and factory automation.
Input voltage range is 85 to 264V AC single phase and the power supplies conform to the safety standards input voltage range of 100 to 240V AC (50/60Hz).
The power supplies are available in five output voltages, 3.3, 5.0, 12, 15 and 24V with respective currents. On both versions, the 3.3V output voltage can be adjusted from 2.85 to 3.63V. All other voltages are set in the factory.
The LHA10F and LHA15F’s switching topology is optimised for higher power LHA series and have an efficiency up to 84.5 per cent at 230V AC 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.
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 3,000V AC input to output isolation voltage, 2,000V AC input to ground and 500V AC output to ground. They offer low leakage currents, the LHA10F has 150 microA max and the LHA15F has 100 microA max at 240V AC/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 are suitable for a range of applications including measurement and analysis equipment, machine tools and industrial robots, display equipment, and semiconductor manufacturing equipment. They comply with the RoHS and Low Voltage directives and carry the CE mark and UKCA.
