Badger II Power Supply Operator’s Manual
Mechanical Considerations
The Badger II can be mounted on either of two surfaces using standard 8-32 size screws. Maximum allowable
torque is 20 in/lbs., and the maximum penetration is 0.18 in. (4.5 mm).
When selecting a mounting location and orientation, the unit should be positioned so airflow is not restricted.
Maintain a 2″ (50,8 mm) minimum clearance at both ends of the Badger II, and route all cables so airflow is not
obstructed. The power supply draws air in at the fan/AC input side and exhausts air out the load side. If airflow
ducting is used, avoid sharp turns that could create back pressure. The fans move approximately 75 CFM of air.
Avoid excessive bending of output power cables after they are connected to the output terminals. For high-
current outputs, use cable ties to support heavy cables and minimize mechanical stress on connectors. Be care-
ful not to short out to neighboring outputs. The maximum torque recommended on output nuts is 10 in/lbs.
Badger II Do’s and Don’ts
 Run the output (+/) power cables next to each other to minimize inductance.
 Insert proper fault protection at power supply input terminals (i.e., a fuse).
 Use proper size wires to avoid overheating and excessive voltage drop.
 Do not attempt to repair or modify the power supply in any manner.
 Do not restrict airflow to the unit. The cooling fan draws air into the unit and forces it out at the output
power terminals.
 If sense jumpers are removed, do not leave sense lines open. Use twisted pair 22-24 AWG wire when
installing Remote Sense.
