TECHNICAL DATASHEET PMF Panel Mount Power Supply 5 V 275 W 1 Phase / PMF-5V320WC PMF Highlights & Features Universal AC input voltage range Built-in active PFC and automatic fan speed control Full corrosion resistant aluminium casing Conforms to harmonic current IEC/EN/BS EN 61000-3-2, Class A and Class D Cold start -20C at 100% load (275 W) Remote ON/OFF is available as an option Safety Standards CB Certified for worldwide use Model Number: PMF-5V320WC Unit Weight: 0.86 kg (1.90 lb) Dimensions (L x W x H): 215 x 115 x 50 mm (8.46 x 4.53 x 1.97 inch) General Description The PMF panel mount power supply series currently offers nominal output voltages of 5 V. These power supply units come with universal AC input from 85 Vac to 264 Vac and wide operating temperature of -10C to +70C. The built-in active PFC provides high power factor and conforms to harmonic current IEC/EN/BS EN 61000-3-2, Class A and Class D. This versatile series has two different connector options (Front Face and Terminal Block) to satisfy different application needs. Remote ON/OFF function is also available for the PMF series. All PMF power supplies conform to major international safety standards including IEC/EN/UL 62368-1 standards and are fully compliant with RoHS Directive for environmental protection.
