100W and 150W PCB power supplies for industrial equipmentTDK-Lambda UK is introducing the ZWS-BAF series PCB-type AC-DC power supplies, which the company says effectively improves the total performance of its previous ZWS-AF series. By combining high efficiency (even at low load conditions) with a wide operating temperature range, small size and ten-year electrolytic capacitor life, TDK-Lambda says these 100W and 150W PCB power supplies for industrial equipment offer customers a genuine advantage.

Boasting features such as active power factor correction (PFC) and high input transient protection, the ZWS100BAF and ZWS150BAF supplies operate from a universal input of 85-265V AC or 120-370V DC to meet a wide range of applications, including factory automation, test and measurement, and LED signage. Offered with a choice of output voltages from 3.3V 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.

In comparison to its first generation ZWS-AF series, TDK-Lambda's intelligent design of the ZWS-BAF PCB layout has minimised internal heat losses, resulting in more compact units. Furthermore, the improved heat dissipation provides a wider operating temperature range of -10 to +70degC, enabling 100 per cent load operation in a 50degC environment; the efficiency of the ZWS150BAF-24 model reaches up to 90 per cent, which is considered high for a PCB-type power supply. Over-current and over-voltage protection are standard features, and an optional remote on/off is available.

With active power factor correction that meets the requirements of EN 61000-3-2, the ZWS-BAF models have a 3kV AC input-to-output isolation and meet conducted and radiated EMC conforming to EN 55011/EN 55022-B, FCC-B, VCCI-B. They are delivered with TDK-Lambda's five-year warranty, are safety-approved to UL/CSA/EN 60950-1 and EN 50178, and are CE marked in accordance with the Low-Voltage Directive.
