The PM10 is a DC-DC converter which provides a regulated output at power levels up to 10 watts. It accepts a wide range DC
input and provides a fully isolated, regulated output. In operation, either (or neither) input pin, as well as either (or neither)
output pin can be grounded. PM10 units provide full output power for ambient temperatures up to 70°C, with linear derating
from 70°C to zero power at 105°C. In forced air applications, full output power can be maintained as long as the chassis
temperature, as measured in the center of the unit’s label, is maintained at less then or equal to 100°C.
Note: For safety agency approval of the end use equipment to safety standards (such as UL 1950 3rd Edition, CAN/CSA C22.2
No.950-95, DIN VDE 0805 and EN 60950), the output of the converter is ELV if the input to the converter is ELV; the output of
the converter is SELV only if its input is SELV. W hen the input is between 60Vdc and 75Vdc, the output may be SELV only if
the DC input is reinforced insulated from the AC mains and SELV reliability fault tests are successfully conducted on the DC
power source in combination with the converters (these tests have already been performed on the converters). The input and
output are to be both floating or both grounded. The converter is to be protected by the specified fuse, provided in the
ungrounded leg.

Recommended Circuit Hook up:
1. Input can have -Vin, +Vin or neither terminal grounded. Input ground connection should be placed as close to
PM unit input as possible.
2. Output can have -Vo, +Vo or neither terminal grounded. Output ground connection should be placed as close to
PM unit input as possible.
3. Recommended input fusing: 2A (Buss PCB2, or equivalent)
Input fuse must be connected in series with the ungrounded input lead.
Mechanical Information:
PM10 units are designed for installation on printed wiring boards. The metal chassis has 0.015” taps built in to provide
clearance between the pins and the PC board to allow for wave soldering. During wa ve soldering, the top surface of the board
to which the PM unit is mounted (measured ½” from the edge of the PM unit) should be maintained at a temperature of no
more than 180°C for no more than 30 seconds. The chassis of the PM unit is electrically isolated from both the input and
output circuitry and should be left floating in a typical installation.
