After launching SPV-1500(1500W) series single output enclosed type power supply with programmable output voltage function, MEAN WELL extends its product coverage to the lower wattage of 150W and 300W─SPV-150 and SPV-300 series, now available from ADM Instrument Engineering . By adding 1~5.5 VDC external control signal, the output voltage of both series can be trimmed from 20% to 110% of the rated value, which greatly increases the flexibility to end system users and adequately fulfills equipments which require switching between different output voltages.
SPV-150 and SPV-300 are high frequency design and possess efficiency up to 83% (SPV-150) and 86.5% (SPV-300) respectively. SPV-150 series can be cooled by only free air convection up to 40℃under full load condition while SPV-300 series are cooled by built-in long life DC fan with fan ON/OFF control which can be operated up to 50℃of ambient temperature. With full range input from 88 to 264VAC, these power units are built-in active PFC function and also comply with harmonic current requirement per EN61000-3-2.
Besides standard functions of remote ON/OFF control, protection for short circuit, over voltage, overload (constant current type), and over temperature, SPV-150/ 300 series power supply also comply with certificates per UL, CUL, TUV, CB and CE that can greatly guarantee your safety. Applications include LCD panel burn-in system, IC testing equipment, factory automation, mechanical and electrical industry, or any applications that often need to adjust the output voltage.
