DIMENSION| 25012741mm (LWH)
PACKING| 1.64Kg; 6pcs/10.8Kg/1.1CUFT
NOTE| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. Derating may be needed under low input voltages. Please check the derating curve for more details.

5. There is high possibility to trigger the floating over voltage protection when PV voltage is trimmed from a high voltage level to a lower voltage level at light load or no load condition. It is suggested that turn off the power supply and set PV voltage to the lowest level, then adjust output voltage to a desired value.

6. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSP-750-5)

7. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 720mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)

8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

Function Manual

Remote Sense
The remote sensing compensates voltage drop on the load wiring up to 0.5V . $MEAN-WELL RSP-750-Series-750W-Power-Supply-with-Single-Output-FIG- $9$$

The +S signal should be connected to the positive terminal of the load whereas-S signal to the negative terminal.
By factory default, on CN50, Remote ON-OFF (pin13) and 12V-AUX (pin14), PV(pin5) and PS (pin6), and PC (pin7) and PO (pin8, respectively, are shorted when shipped. The power supply wll have no output if the shorting connector is not assembled unless certain functin needs to be activated.

Remote ON-OFF

The power supply can be turned ON/OFF by using the “Remote ON-OFF” function . $MEAN-WELL RSP-750-Series-750W-Power-Supply-with-Single-Output-FIG- $10$$

Between Remote ON-OFF(pin13) and 12V-AUX(pin14)	Power Supply Status
SW close (Short)	ON
SW open (Open)	OFF

When multiple power supplies need to turn ON/OFF simultaneously by Remote ON- OFF control, -S & -V on CN50, as well as +S & +V, on each power supply should be connected

Output Voltage Programming (or, PV / remote voltage programming / remote adjust / margin programming / dynamic voltage trim)

In addition to the adjustment via the built-in potentiometer, the output voltage can be trimmed to 40~110% of the nominal voltage by applying EXTERNAL VOLTAGE $MEAN-WELL RSP-750-Series-750W-Power-Supply-with-Single-Output-FIG- $11$$

If EXTERNAL VOLTAGE (VDC) <0.5V,the power supply may enter under voltage protection; it needs to be restarted to work.
Caution : By factory default, the Output Voltage Programming is not activated, and PV (pin5) and PS(pin6) are shorted by connector. Whenever this function is not needed to activate, as assumed in other sections’ diagrams, please keep PV (pin5) and PS(pin6) shorted ; other wise, the power supply will have no output.

Constant Current Level Programming (or, PC / remote current programming / dynamic current trim)
The constant current level can be trimmed to 40~110% of the rated current by applying EXTERNAL VOLTAGE. $MEAN-WELL RSP-750-Series-750W-Power-Supply-with- Single-Output-FIG- $12$$

Caution : By factory default, the Output Current Programming is not activated, and PC(pin7) and PO(pin8) are shorted by connector. Whenever this function is not needed to activate, as assumed in other sections’ diagrams, please keep PC(pin7) and PO(pin8) shorted ; otherwise, the power supply will have no output. $MEAN-WELL RSP-750-Series-750W-Power-Supply-with-Single- Output-FIG- $13$$

DC_OK signal
“DC_OK” is an open collector signal. It indicates the output ※ status of the power supply. It can operate in two ways : One is sinking current from external TTL signal ; the other is sending out a TTL voltage signal.

Sinking current from external TTL signal: The maximum sink current is 10mA and the maximum external voltage is 5.6V.
Sending out TTL voltage signal
Between DC- OK(pin9) and GND(pin10 &11)| Output Status
