Description
EN-60950-1 Certified
EN-60601-1 Certified
The ROM Micro Size DC/DC converter has been designed for isolating or converting DC power rails
respectively. It provides a small micro-size package, high efficiency, low output ripple, high 3kVDC
Isolation and an extended –40°C to +85°C operating temperature range.
State of the art packaging and automated manufacturing ensures cost-effectiveness and short lead times.
