Medically approved PCB mounting modules extend application range

PowerPax has extended its offering of PCB Mounting AC/DC module power supplies with the addition of the 5W, medically approved, LD05-20BxxMU series from global power conversion manufacturer Mornsun. The series features single outputs of 5VDC, 12VDC, 15VDC and 24VDC with output voltage accuracy of ±2% typical, line regulation of ±0.5% typical and ripple and noise of 100mV peak to peak max (20Mhz bandwidth). These devices have a minimum load requirement of 0A, a stand-by power consumption of 0.3W maximum and a hold up time of 80mS typical (input 230VAC). All models within this range feature output short circuit protection (continuous self-recovery), over-current protection and over-voltage protection. These modules are Class II (double insulated) and can be powered from either an AC or DC with an input range of 85–264VAC (47–63Hz) and 100-370VDC respectively. The input to output isolation is 4000VAC, maximum leakage current is 80µA maximum and the insulation meets level 2 x MOPP. They feature low power consumption with an input to output efficiency of up to 81% and offer good EMC performance. This series is housed in a compact flame-retardant and heat resistant case (UL94-V0 rated) that measures 53.8mm x 28.8mm x 19mm. They have a wide operating temperature range of -25C to +70C and a high MTBF of > 300K hrs (MIL-HDBK-217F@25C). This range is approved to EN60601/UL60601 and is particularly suited to medical applications, although they can also be used for other applications including industrial control, instrumentation, telecommunications and civil applications.
