Cosel unveils four UL/EN62368-1-certified open frame power supplies
Four open frame, low profile, compact power supplies announced by Cosel cover 30 to 100W and are UL/EN62368-1 certified. The LHA30F, LHA50F, LHA75F and LHA100F complement Cosel’s existing LHA150F and LHA300F models for a portfolio ranging from 30 to 300W for demanding industrial applications.
Benefiting from the latest power switching technologies, the LHA30-50-75-100F power supplies have a typical efficiency up to 90 per cent high-line and 86 per cent low-line. In addition, by using partial resonance technology, noise and ripple levels have also been reduced. The power supplies offer a wide temperature range from -10 to +70 degrees C.
The family, from the 30W LHA30F to the 300W LHA300F is UL/EN 62368-1-certified for use in industrial applications where safety is vital.
The LHA30-50-75-100F power supplies are designed for worldwide applications, with an input voltage range of 85 to 264V AC single phase and conform to the safety standards input voltage range of 100 to 240V AC (50/60Hz).
The 30W LHA30F is available in five output voltages, 3.3, 5.0, 12, 15 and 24V. The LHA50-75F is available in seven output voltages, 3.3, 5.0, 12, 15, 24, 36 and 48V, while the LHA100F is available in 5.0, 12, 15, 24, 36 and 48V.
Standard products are delivered with a factory trimmed output voltage; it is possible to order the LHA30-50-75-100F with a built-in potentiometer for customers requiring the capability to adjust the voltage up and down.
The LHA30-50-75-100F automatically switches to energy-saving mode using intermittent pulse modulation. Other features are inrush current protection, over-current protection with automatic recovery when the default is removed, and over-voltage protection.
The units can be mounted in any orientation, although, depending on the ambient temperature and environment, a derating may apply counselled Cosel.
In conducted noise tests, the LHA30-50-75-100F power supplies comply with FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B, and EN55032-B. For further improved noise performance Cosel offers EMI/EMC filters type EAC-03-472.
The units have a 3,000V AC input to output isolation voltage, 2,000V AC input to ground and 500V AC output to ground.
The LHA30F measures 50 x 27 x 87.5mm (1.97 x 1.07 x 3.44-inches) and weighs 100g (maximum). The LHA50F measures 50 x 27 x 112mm (1.9 7 x 1.07 x 4.41- inches) and weighs 140g (maximum). The LHA75F measures 50 x 27 x 150mm (1.97 x 1.07 x 5.91-inches) and weighs 190g (maximum) and the LHA100F measures 62 x 27 x 155mm (2.44 x 1.07 x 6.10-inches) and weighs 250g (maximum).
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 LHA30-50-75-100F power supplies are suitable for measurement and analysis equipment, machine tools and industrial robots, display equipment, and semiconductor manufacturing equipment.
