PSB Series
Positive Switching Regulator
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 144V 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.
The case design allows for operation up to 71 °C. The PSB Series
is designed for wall or chassis mounting with faston connectors.
Various options are available to adapt the converters to different
applications.
