Single output power supply

Paul Boughton

TDK Corporation announces the new TDK-Lambda ZWS-BP series of single output, PCB-type AC-DC power supplies.

Based on the popular ZWS series, the ZWS-BP is 30 per cent smaller than its predecessor, thus simplifying equipment design and is offered in two mid-power output models – ZWS150BP (150W) and ZWS240BP (240W).

With a 200 per cent peak power capability, the ZWS-BP is suitable for use in electromechanical equipment, such as motors, disk drives, pumps, fans and actuators, which require a high initial start-up current.

The ZWS-BP is equally suited for use in a wide range of light industrial equipment and front-end equipment for broadcast and communications applications, and for applications in indoor and outdoor LED lighting and signage and test & measurement.[Page Break]
Operating from a universal input of 85 to 265Vac or 120 to 370Vdc, the ZWS-BP series is a compact product that offers an efficiency of up to 91 per cent. All models are convection cooled with an operating temperature of -10°C to 50°C at 100 per cent load, allowing 75 per cent load operation at 60°C.
Rated with nominal outputs of 24V, 36V and 48V, with each model being user adjusted by up to ±10 per cent, the ZWS-BP series can accommodate a wide range of non-standard system voltages.

Standard features include power factor correction (PFC) and over current and over voltage protection; options include a remote on/off feature, conformal coating of the PCB, L-plate or L-plate plus cover and an additional terminal block (240W models only).
