Reinforcing TDK-Lambda’s ‘green’ product initiative, the ZWS-B series printed circuit board type AC-DC power supplies feature less than 0.5W no load input power. This ensures that they comply with the energy related products (ErP) directive. It also makes them ideal for a range of light industrial equipment and front-end equipment for broadcast and communications applications, as well as indoor and outdoor LED signage and test and measurement.
Three low power models are available, all boasting an efficiency of up to 86 per cent. These convection-cooled power supplies feature an operating temperature range of -10 to 70°C, allowing 100 per cent load operation in a 50°C environment and 70 per cent load at 60°C.
Operating from a universal input of 85 to 265V AC or 120 to 370V DC, the ZWS-B series is offered with a choice of output voltages from 3.3 to 24V. Each model can be adjusted by ±10 per cent of its nominal voltage to accommodate non-standard system voltages.
