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.
