Installation Data Sheet
PM10-12S DC-DC Converters
Recommended Circuit Hook up:
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 wave 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.

Input can have -Vin, +Vin or neither terminal grounded. Input ground connection should be placed as close to
PM unit input as possible.
Output can have -Vo, +Vo or neither terminal grounded. Output ground connection should be placed as close to
PM unit input as possible.
Recommended input fusing: 2A (Buss PCB2, or equivalent)
Input fuse must be connected in series with the ungrounded input lead.
