PMR-4V320WD☐A
Unit Weight:
0.86 kg
Dimensions (L x W x D):
215 x 115 x 30 mm
General Description
The PMR-4V320WD☐A offers nominal output voltage of 4.2V with a wide operating temperature range from -20°C to +70°C and can
withstand shock and vibration according to IEC 60068-2. The product comes with universal AC input voltage range at 88Vac to 264Vac.
At only 30mm height and encased in a full corrosion resistant aluminium casing, the PMR series is made for installation in narrow
space while its built-in active PFC circuit provides high power factor values and conforms to harmonic current emission according to
IEC/EN 61000-3-2, Class A and Class D.
