Description

RSP-3000 is a 3KW single output enclosed type AC/DC power supply. This series operates for 180-264VAC input voltage and offers the models with the DC output mostly demanded from the industry. Each model is cooled by the built-in fan with fan speed control, working for the temperature up to 70C. Moreover, RSP-3000 provides vast design flexibility by equipping various built-in functions such as the output programming. active current sharing, remote ON- OFF control, auxiliary power, etc.

Function Manual

Remote Sense
The Remote Sense compensates voltage drop on the load wiring up to 0.25V Caution: The power supply, by factory default(also the assumption for other sections), is shipped with, -S & -V on CN2, as well as +S & +V, shorted by
connector. When activating the Remote Sense, the +S signal should be connected to the positive terminal of the load whereas-S signal to the negative terminal of the load.
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 20-110%(Typ.) of the nominal voltage by applying EXTERNAL VOLTAGE.
Connecting an external DC source between PV &-S on CN2, and +S & +V, -S & -Valso need to be connected.

Please do not adopt PWM signal as the EXTERNAL VOLTAGE.
The rated current should change with the Output Voltage Programming accordingly.

Caution:

By factory default, the Output Voltage Programming is not activated, and PV(PIN3) and PS(PIN4) of CN2 are shorted by connector. Whenever this function is not needed to activate, as assumed in other sections’ diagrams, please keep PV(PIN3) and PS(PIN4) of CN2 shorted ; otherwise, the power supply will have no output.
PV/PIN3) and PS(PIN4) of CN1 or CN2 must be disconnected if “Output Voltage Programming” function is used; otherwise, the internal electrical components may be damaged, and the power supply unit may thus be out of order.
Remote 0N-OFF
Remote ON-OFF is activated by the configuration with respect to CN1,CN2 and CN3 as shown in the following diagram.
By factory default, PV(PIN3) and PS(PIN4) on CN2 are shorted by connector; likewise, OLP(PIN9) and OL-SD(PIN10) on CN3 are shorted when shipped.
Example 3.2(A): Using external voltage source
Example 3.2(B): Using internal 12V auxiliary output
Example 3.2(C): Using internal 12V auxiliary output Connection Method
Alarm Signal Output
Alarm signal is sent out through “P OK” & “P OK GND” and POK2 & P OK GND2 pins on CN3. Please acknowledge an external voltage source is required for this function.
By factory default, OLP(PIN9) and OL-SD(PIN10) on CN3 are shorted by connector when shipped.
Select Overload Protection Type
Insert the shorting connector on CN3 that is shown in Fig 5.2, the Overload Protection Type will be “constant current limiting with delay shutdown after 5 seconds, re-power on to recover”. This is the factory default.
Remove the shorting connector on CN3 that is shown in Fig 5.1, the Overload Protection Type will be “continuous constant current limiting”.
Overload Protection Type: constant current limiting with delay shutdown after 5 seconds Overload Protection Type: constant current limiting
Current Sharing with Remote Sense
RSP-3000 has the built-in active current sharing function and can be connected in parallel, up to 3 units, to provide higher output power as exhibited beloW:
The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
Difference of output voltages among parallel units should be less than 0.2V.
The total output current must not exceed the value determined by the following equation:
Maximum output current at parallel operation=(Rated current per unit) X (Number of unit) X 0.9
When the total output current is less than 3% of the total rated current, or say (3% of Rated current per unit) X (Number of unit) the current shared among units may not be fully balanced.
When remote sensing is used in parallel operation, the sensing wire must be connected only to the master unit
Sense lines should be twisted in pairs to minimize noise pick-up.
+S,-S and CS on CN1 or CN2are connected mutually in parallel.
Under parallel operation, the “output voltage programming” function is not available.
Three Phase Connect
Users can exploit three units of RSP-3000(unit 1 ,unit 2,unit 3) to work with 3 power system. Please refer to following diagrams for configuration.
