Final Test
Data
This lists the performance data recorded by our quality
assurance staff during final inspection and testing of your power module. Parameters
measured include input and output voltage and current, line and load regulation, ripple or
distortion, and output frequency (for inverters). |

Testing
Instructions and Application Notes
This pamphlet list general instructions for testing and using the power module. It
includes maximum ratings for heat dissipation, mounting instructions, environmental
requirements, and similar. |
| 3. |
Thermal
Compound
This special, grease-like material fills the minute air gaps between mating surfaces and
enables the power supply to transfer a maximum amount of heat to the sink. Apply
thermal compound to the base of the power module before mounting it to the heat sink. |
| 4. |
Mounting
Studs (Upon Customer
Request)
Standard mounting hardware accompanying each unit consists of one-inch long steel studs,
with slotted cup points, upon customer request. |
Mounting
Martek Power Abbott power modules will operate safely in most mounting orientations,
subject to the following guidelines: |
| 1. |
Mounting
Surfaces
Mounting surfaces must be smooth, flat to within 0.005, cover the entire baseplate of the
module, and have adequate heat dissipation characteristics. (To facilitate
heat transfer, we recommend the use of thermal compound, covering at least 95% of the
contact area, applied between the baseplate of the unit and the mounting surface.) |
| 2. |
Stud
Mounting
Most Martek Power Abbott power modules come with standard 10-32 stud-mounting hardware and
some with 6-32 or 4-40 hardware. Torque the nut on the 10-32 mounting studs to 15
inch-pounds, 6 inch-pounds on the 6-32, and 4 inch pounds on the 4-40 studs.
Customer furnished mounting studs should not exceed a penetration of five threads. |
Label
Every Martek Power Abbott power supply has a
nameplate that specifies pin designations, electrical ratings, and the recommended input
fuse rating. Carefully read the label and the instruction pamphlet accompanying each
module before attempting to use it.
Wiring
The proper wire guage to use in connecting a power module depends on the length
of the wire needed, the ambient temperature, and the rated input and output current of the
module. We recommend 1,000 circular mils per ampere as a general rule to use in choosing
wire guage. For additional information, refer to the "Conductor Size and
Resistance" topic of the Power Supply Applications Notes. |
For further explanation of these guidelines,
please see the "Instructions for Testing and Applications" pamphlet accompanying
each unit, or request detailed test procedures from the factory through your Martek Power
Abbott sales representative. |
