Features
Unregulated
Converters
• Ultra-compact size - only 8.3 x 8.3 x 6.8mm
• 1kVDC/1s or 2KVDC/1s basic isolation
• Optional continuous short circuit protected
• Fully encapsulated
• UL and EN certified, CB report
• Efficiency to 84%
Description
The RNM series DC/DC converters are ultra-compact isolated single output converters for applications
where board space is at a premium. Despite their small size, the converters are fully featured with a
full industrial operating temperature range of -40°C to +85°C without derating (+100°C with derating),
1kVDC or 2kVDC isolation and optional short circuit protection. The converters are also UL-60950-1
and EN-60950-1 certified and have a CB Report.

Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the
capacitive load that will allow start up in under 1s without damage to the converter
