Application Notes:
Remote sense and trim functions
To use the remote
sense, connect the "Sense +" and "Sense -" terminals to wires that go to the load and don't carry any current. This lets the DC
converter stabilize the voltage at the load, compensating for voltage loss in the wires that carry current.
In other words,
without using the "Sense" terminals the voltage will be stabilize at the converter output terminals. As the current flows
through wires, connectors, and contacts then resistance of these elements will cause a voltage drop due to Ohm's law. If you
run an extra set of wires from the sense terminals to the load that don't carry current, then these can be used to sense the
actual voltage at the load and the converter will boost its voltage to compensate for this voltage drop (over a limited range,
±0.5 Volts.)
The sense terminals can also be used to trim the voltage with fixed resistors or a pot as follows:
Schematic of how to
trim the output voltage. Fixed resistors would also work, they should add to about 10k Ohms.
Cooling
No
heat sink is necessary at ambient temperatures below 30°C. At higher ambient temperatures derate the current or supply a
flow of up to 200LFM (linear feet per minute) cooling air is provided (at 100°C ambient). This can be supplied by a 10
cubic feet per minute fan that is about 2.5 inches square. Pentium cooling heat-sink-fan combinations will also do
this.
Standard heatsinks are available for half-brick modules such as Wakefield 517-95AB, 527-45AB, 527-24AB, 518-95AB,
528-45AB, 528-24AB, or the less expensive CUI VHS-45 or VHS-95.

Printed circuit board dimensions are 107mm x 76mm (4.2 x 3.0 inches)
The fully populated board dimensions are 107mm x
76mm x 23mm (4.2 x 3.0 x .9 inches). It includes connectors for Vin and Vout as well as inhibit and Sense terminals. The board
mounting holes are 3.6 mm (0.143 inch) in diameter 64mm x 95mm center to center spacing.
NOTE! the faceplate
temperatures are definitely in the "burn your fingers" category and care should be taken to prevent human contact.
