240 W enclosed with PFC

September 2009 Electrical Power & Protection

MEAN WELL has announced the SP-240 series as successor to the S-240 (240 W) range due to be phased out at the end of the year. The SP-240 is a single output enclosed type power supply with built-in active power factor correction (PFC) functionality, designed to cover both the features and dimensions of the S-240. For instance, the same locations of mounting holes and DC fan have been kept, but the total height has been lowered by 15 mm, so that designers can easily integrate with existing mechanisms without changes.

SP-240 now fills the gap in enclosed type power supplies with PFC function between 200 and 320 W, allowing MEAN WELL to offer users a more complete product range.

The series incorporates built-in active PFC which is superior to the passive PFC design of S-240. With full range input from 88 to 264 VAC, this series has the same output voltages options (5 V/7,5 V/12 V/15 V/24 V/30 V/4 V) as S-240. Featuring up to 89% operating efficiency, the supplies have better energy conversion by 1–4% than the previous models. SP-240 series also equipped with a long life DC fan with fan ON/OFF control circuit allowing it to be operated at up to 70°C ambient temperatures.

In addition, this new power unit is designed with single sided PCB to achieve cost reduction. SP-240 series has standard functions of adjustable output voltage by internal potential meter, protection for short circuit, overload, over-voltage and over-temperature. All series comply with international safety standards per UL/CUL/TUV/CB/CE.

Suitable applications include industrial automation, moving sign, electronic equipment, and instrumentation.
