PSA153 Datasheet Positive Switching Regulator

Manufacturer: Bel Fuse

Overview: 25 1.0" 50 2.0" 70 2.8" PSA/PSR Series Positive Switching Regulator 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. Various options are available to adapt the regulators to different applications.

This datasheet includes multiple variants, all published together in a single manufacturer document.
