Application Notes:
Remote sense and trim functions
To use the remote
sense, connect the "Sense +" and "Sense -" pins 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 stabilized 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 if a flow of 200LFM (linear feet per minute) cooling air is provided. This can be supplied by a 10 cubic
feet per minute fan that is about 2.5 inches square. Pentium cooling heat-sink-fans 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.
If you have no active cooling derate the output current according to the
following table

still, open air, 23°C ambient. |
