PSA / PSR Series

Bel Power Solutions PSS/PSK series of positive switching regulators offer up to 97% efficiency across their 8 ~ 144 VDC input voltage range, with 3.3 to 48 VDC output capacity, as well as 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 PSB Series highly efficient power up to 96% over its 8 ~ 144 VDC input voltage range, as well as a maximum of 6 A output power, delivered by a single output. This series has no derating over temperature and low input-output voltage differential.

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 ºC. 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.
