TDK-Lambda UK has extended its ZWS-BAF series of PCB-type AC/DC power supplies by adding two lower-power models, suitable for use in factory automation, test and measurement and LED signage.

The 50W ZWS50BAF and 75W ZWS75BAF are designed to combine high efficiency at low-load conditions with a wide operating temperature range, small size and up to 10 years of electrolytic capacitor life.

As with all models in the ZWS-BAF series, the new low-power models have active power factor correction (PFC) and high-input transient and surge protection to IEC61000-4-4,5.

They operate from a universal input of 85-265VAC or 120-370VDC, making them suitable for a wide range of applications, including factory automation, test and measurement and LED signage.

Offered with a choice of output voltages from 3.3V to 48V, each model in the ZWS-BAF series can be adjusted by up to +/-10 per cent of its nominal voltage to accommodate non-standard system voltages.

Small in size and offering an efficiency of up to 88 per cent, all models in the ZWS-BAF series feature an operating temperature range of -10C to 70C, allowing 100 per cent load operation in a 50C environment.

Standard features include over-current and over-voltage protection circuitry, while an optional remote on/off is also available.

With active PFC that meets EN61000-3-2, the ZWS-BAF models have a 3kVAC input-to-output isolation and meet conducted and radiated EMC conforming to EN55011/EN55022-B, FCC-B, VCCI-B.

They are delivered with TDK-Lambda’s five-year warranty, are safety approved to UL/CSA/EN60950-1 and EN50178 and carry the CE mark, according to the LV Directive.
