Description
safety standards IEC/EN/UL 60950-1 2nd Edition. The con-
verters 24IMX70 and 40IMX70 exhibit basic insulation for the
specified input voltage, the converters 110IMY70 have
reinforced insulation.
The IMX/IMY70 Series of board-mountable 70 Watt DC-DC
converters has been designed according to the latest industry
requirements and standards. The converters are particularly
suitable for use in mobile or stationary applications in
transport, railways, industry, or telecommunication, where
variable input voltages or high transient voltages are
prevalent.
The circuit is comprised of 2 planar magnetic devices. All
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 65 °C in free air and up to 95 °C with
forced cooling. For extremely high vibration environments the
case has holes for screw mounting.
Covering a total input voltage range from 14.4 V up to 150 V
with 3 different models, the converters are available with one
or two electrically isolated outputs from 5 V to 48 V, externally
adjustable and with flexible load distribution. A shutdown input
allows remote converter on/off. Features include consistently
high efficiency over the entire input voltage range, high
reliability, and excellent dynamic response to load and line
changes.
The converters are designed according to the international
