This DC converter uses state of the art technology to cram 150 watts of 5V goodness into a half-brick size. These are made by a tier-1 manufacturer, are extremely reliable, and we are selling them at 2/3 of the Digikey price. These DC/DC bricks are usually long lead-time items, but we have these in stock for immediate delivery.. SV48-5-150-1 DC to DC 150 watt converter with a wide input voltage range, 36VDC-75VDC. This makes it useful for creating 5V at up to 30 amps in 24V and 28V systems.
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. NOTE! these faceplate temperatures are definitely in the "burn your fingers" category and care should be taken to prevent human contact.
