The PSA/PSR Series of positive switching regulators are designed as power supplies for electronic systems when 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 especially designed for secondary-switched and battery-driven mobile applications. The regulators are suitable for railway applications according to EN 50155 and EN 50121.
The case design allows for operation up to 71 °C. The PSA/PSR Series are designed for wall or chassis mounting with faston connections or with solder pins for insertion into a PCB.
