battery-driven mobile applications. The converters are suitable
for railway applications according to EN 50155 and EN 50121.
The PSB Series of 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
Two type of housings are available allowing operation up to
71 °C. The PSB Series is designed for wall or chassis mounting
with faston connections.
Various options are available to adapt the converters to different
applications.
