PSK4812-9EG

The PSK Series of positive switching regulators is 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 50121Two type of housings are available allowing operation up to 71°C. They are designed for insertion into a 19" DIN-rack or for chassis mounting. Replacing the heat sink by an optional cooling plate, allows chassis or wall mounting on top of a metal surface, acting as heat sink."
