For good power supply design it is essential to understand the application and the environment in which it operates.
For good power supply design it is essential to understand the application and the environment in which it operates. With the introduction of the ZWS-BAF series of PCB-type AC-DC power supplies, TDK-Lambda has effectively improved the total performance of its previous generation ZWS-AF series. The improved heat dissipation of the new series provides a wider operating temperature range of -10 to +70°C. Efficiency of the ZWS150BAF-24 model is as high as 90%.
Offering advanced features such as active power factor correction and high input transient protection, the 100 W ZWS100BAF and 150 W ZWS150BAF series operate from a universal input of 85 to 265 V AC or 120-370 V DC to meet a wide range of applications. These include factory automation, test and measurement, and LED signage. Available with a choice of output voltages from 3,3 V to 48 V, each model in the series can be adjusted by up to 10% of its nominal voltage to accommodate non-standard system voltages.
