Mean Well Introduces New Series of 16/25W AC Phase-Cut Dimming LED Power Supplies

Power supply plays an important role in the LED lighting system, hence, MEAN WELL has announced two new 16 and 25W ac phase-cut dimming LED power supplies – PCD-16/25, to work with TRIAC dimmers at the ac input side and to fulfill the dimming requirement in indoor LED lighting markets. The PCD-16/25 series are compatible with both leading edge and trailing edge TRIAC dimmers, which the company says are superior to the others in market that good for only leading edge or trailing edge.

To conform with different utility inputs all over the world, the PCD-16/25 offers two options for users: 115Vac (90~135Vac) /A type and 230Vac (180~295Vac) /B type. In addition, these two series are designed with single stage PFC topology, so that they can meet the requirements of high power factor (PF≧0.9) and EN61000-3-2 Class C (harmonic current) for the lighting industry. Efficiency of the PCD-16/25 series are as high as 82% and hence can operate between -30 +60°C by only free air convection which fit to the enclosed installation for indoor embedded lighting systems.

Other standard functions include protections for short circuit, overload, and over temperature. For flexible installation, the PCD-16/25 equip with input/ output wires 7.5cm/18AWG and 15cm/18AWG respectively. These new models comply with lighting certificates per CE (EN55015 and EN61547) / FCC Part 18, and also design refer to UL8750 and EN61347-2-13, which are very suitable for working with traditional TRIAC dimmer in LED indoor lighting application. Meanwhile, MEAN WELL states that it had tested many well-known brands of TRAIC dimmers with the PCD-16/25 and got good compatibility results in lowest dimming degree and operating stability.
