Features
Unregulated
Converters
• High 6.4kVDC isolation
• Wide operating temperature range from
-40°C to +90°C without derating
• High capacitive load capability
• Continuous short circuit protection
• Efficiency up to 80% RK/H6 & RH/H6
Description
The RK/H6 and RH/H6 series 1W DC/DC converters feature high 6.4kVDC isolation and an extended
operating temperature range up to +90°C without derating, yet are lower cost than standard high
isolation converters. They are suitable for demanding industrial and high isolation test and measurement
applications.
