where isolated output voltages are required. These
converters offer a feature/option set including:
through-hole mounting, positive or negative logic
(remote on/off), over-current & over-temperature
protection, under-voltage lockout. The input voltage
range covers the standard Industrial requirements
with a regulated output voltage and power rating
up to 15W.
Modules provide voltage isolation (basic
insulation) from input to output of up to 1600V. The
Operating Ambient Temperature Range is -40°C
to +85°C.The Module delivers full output power
to +70°C with no airflow. These parts are ideal for
applications that do not require any heat sinking or
forced air cooling.

Notes
➀
Unless otherwise noted, all specifications are at nominal input voltage, nominal out-
put voltage and full load. General conditions are +25˚ Celsius ambient temperature,
near sea level altitude, natural convection airflow. All models are tested and specified
with external parallel 1 μF and 10 μF output capacitors. The external input capacitor
is 100 μF. All capacitors are low-ESR types wired close to the converter.
➁
Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth.
Input filtering is Cbus=220 μF, Cin=33 μF and Lbus=12 μH.
