AC-DC Power Supplies

ASB75 Series

Baseplate cooled 75W half-brick AC-DC power supplies with built-in fuse & EMC filter

The ASB75 series is a range of low profile, half brick, baseplate cooled AC-DC power supplies which require no external components.

The series includes a built in EMC filter and AC fuse as well as bulk storage capacitor providing a complete AC-DC power solution ready for installation into end applications.

The ASB75 offers high efficiency to minimise waste heat and heat sinking requirements and operates from -40°C to +85°C on the module baseplate.
