Description
The PSC and PSL Series positive switching regulators are designed as power supplies for electronic systems, where no input-to-output isolation is required. Their major advantages include a high level of efficiency, high reliability, low output ripple, and excellent dynamic response. Models with input voltages up to 144 V are specially designed for secondary switched and battery-driven mobile applications. The converters are suitable for railway applications according to EN 50155 and EN 50121.
Two type of housings are available allowing operation up to 71 °C. The PSC Series is designed for wall or chassis mounting with faston connections, whereas the PSL Series is designed for insertion into a 19" DIN-rack and exhibits a H11 connector.
Various options are available to adapt the converters to different applications.
