The HS-series from HAHN is a EuP, VDE- and UL approved 3W power AC-DC converter in EI30 housing. Based on switch mode technology these transformers offer a voltage transfer loss of < 0.15 W and an efficiency of over 70 percent and are aimed at applications within the broad input voltage range of 85 to 265V for power supplies.

These transformer fulfill the EuP Directive requirements for the reduction of standby power loss to under 150mW. The HS-series is a pin-to-pin solution that makes it easy to upgrade existing applications to EuP requirements. The packaging means external components such as a rectifier, capacitor and voltage regulator is no longer necessary.

The HS-design kit (DK3-HAN) contains one each of all the available HS4 AC-DC converters to simplify the development of prootype systems.
