What's great about the CHS series?

Power module-type DC-DC converters compatible with 24V and 48V power systems.
Featuring our proprietary digital assist control for high efficiency (up to 96%) and low noise.
The world-standard brick size boosts power density, contributing to energy savings and simplified thermal design.
An electrolytic capacitor-free design ensures long life, while conduction cooling makes it ideal for fanless, silent equipment.
