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 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.

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.
