Unregulated
Converters
• 3kVDC/1s or 4kVDC/1s isolation
• Optional continuous short circuit protection
• UL94V-0 package material
• Efficiency up to 84%
• Suitable for IGBT applications RK & RH
Description
The RK and RH Series DC/DC-Converter complements RECOM’s industrial range of converters with
very high isolations of 3kVDC/1s and 4kVDC/1s. The extended operating temperature range covering
–40°C to +90°C is a standard feature. The converters are IEC/EN/UL60950-1 certified, and are suitable
for IGBT driver applications.

Notes:
Note3: standard part is without Continuous Short Circuit Protection
add suffix „/P“ for Continuous Short Circuit Protection
Note4: add suffix „/H“ for 4kVDC/1s Isolation
or add suffix „/HP“ for Continuous Short Circuit Protection and 4kVDC/1s Isolation
Ordering Examples:
RH-123.3D/P: 12V Input Voltage, ±3.3V Output Voltage, Dual Output with continuous short circuit protection
RK-0509S/HP: 5V Input Voltage, 9V Output Voltage, Single Output with 4kVDC/1s Isolation and continuous short circuit protection
