PCB-type power supplies

27 April 2011 Power Electronics / Power Management

TDK-Lambda has extended the reach of its ZWS-BAF series of PCB-type AC-DC power supplies by adding two lower-power models. The 50 Watt ZWS50BAF and 75 Watt ZWS75BAF combine high efficiency even at low load conditions, with a wide operating temperature range, small size and up to 10 year electrolytic capacitor life.

As with all models in the ZWS-BAF series, the new models have active power factor correction and high input transient and surge protection to IEC61000-4-4,5, and operate from a universal input of 85 to 265 V a.c. or 120–370 V d.c. to meet a wide range of applications, including factory automation, test and measurement, and LED signage. Offered with a choice of output voltages from 3,3 V to 48 V, each model in the range can be adjusted by up to ±10% of its nominal voltage to accommodate non-standard system voltages.

Small in size and offering efficiency up to 88%, all models in the ZWS-BAF series feature an operating temperature range of -10°C to +70°C, allowing 100% load operation in a 50°C environment. Standard features include over-current and over-voltage protection circuitry; an optional remote on/off is also available. With active power factor correction that meets EN61000-3-2, the power supplies exhibit 3 kV a.c. input to output isolation and meet conducted and radiated EMC conforming to EN55011/EN55022-B, FCC-B, VCCI-B. They are delivered with a five-year warranty, are safety-approved to UL/CSA/EN60950-1 and EN50178 and carry the CE mark, according to the LV Directive.
