IMX70 / IMY70 Series

70 to 90 Watt DC-DC Converters

© 2018 Bel Power Solutions & Protection

Description

converters exhibit basic insulation for the specified input voltage, whereas the 110IMY70 converters have reinforced insulation.

The circuit is comprised of 2 planar magnetic devices. The components are automatically assembled and securely soldered onto

a single PCB without any wire connection. Magnetic feedback ensures maximum repeatability in the control loop over all operating

conditions and best reliability. Careful consideration of possible thermal stress ensure the absence of hot spots, such providing

long life in environments, where temperature cycles are present. The thermal design without using any potting material allows

operation up to an ambient temperature of 70 °C in free air and up to 100 °C with forced cooling. For extremely high vibration

environments the case has holes for screw mounting.
