6. Betjening
6.1. Remote ON/OFF Function
The power supply can be remotely turned ON or OFF by applying voltage to the control pins (CN1 & CN2 & CN3). Refer to the following table and diagrams for connection examples.
| Tilslutningsmetode | Fig. 1.2(A) | Fig. 1.2(B) | Fig. 1.2(C) |
|---|---|---|---|
| SW Logik | Udgang på | SW åben | SW åben |
| Udgang slukket | SW Luk | SW Luk |
Figur 6.1: Examples of connecting remote ON/OFF. This image provides three circuit diagrams (A, B, C) illustrating different methods for implementing the remote ON/OFF function using external voltage sources or the internal 12V auxiliary output, showing connections to AUX, RCG, RC, SW, and AUXG pins.
- (A) Using external voltage kilde: Connect an external 12V source to control the SW pin.
- (B) Using internal 12V auxiliary output: Utilize the power supply's internal 12V AUX output for control.
- (C) Using internal 12V auxiliary output: Another configuration using the internal 12V AUX output for control.
6.2. Alarmsignaludgang
The power supply provides alarm signals via P OK and P OK2 GND pins. An external voltagDer kræves en kilde til denne funktion.
| Fungere | Beskrivelse | Output of alarm (P OK, Relay Contact) | Output of alarm (P OK2, TTL Signal) |
|---|---|---|---|
| P OK | The signal is "Low" when the power supply is above 80% of the rated output voltage. | Lav (maks. 0.5V ved 500mA) | Lav (maks. 0.5V ved 10mA) |
| The signal turns to be "High" when the power supply is under 80% of the rated output voltage or Power Fail. | Høj eller åben (Ekstern anvendt voltage, 500mA maks.) | Høj eller åben (Ekstern anvendt voltage, 10mA maks.) |
Figur 6.2: Internal circuit of P OK (Relay, total is 10W) and P OK2 (Open collector method). These diagrams show the internal circuitry for the alarm signal outputs, including connections for external voltage and resistance for both P OK and P OK2.
6.3. Udgang Voltage Trim
Output voltage can be trimmed between 20% and 110% of the rated output voltage. The PV (PIN3) and PS (PIN4) of CN1 or CN2 must be disconnected if "Output Voltage TRIM" function is used. Otherwise, the internal electrical components may be damaged, and the power supply unit may thus be out of order.
Figur 6.3: Udgang Voltage Trimming. This section of the image includes a diagram showing how to add an external 1-6V external voltage for trimming, and two graphs: one illustrating output voltage vs. external voltage, and another showing output current vs. output voltage procenttage.
- Connect +S and -S to the load.
- Connect +V and -V to the load.
- Justering af output voltage is possible between 20-110% (Typ.) of the rated output which is shown in Fig. 3.2. Reducing output current is required when the output voltage is trimmed up.
6.4. Aktuel deling
Up to 2 units can share current in parallel. For optimal performance, ensure the voltage difference among each output should be minimized (less than 0.2V).
Figur 6.4: Current Sharing Connection. This diagram illustrates how to connect multiple RSP-2400 units (Master, Slave 2, Slave 3) in parallel for current sharing, showing the connections for AC/L, AC/N, FG, +V, -V, +S, and -S terminals.
- Connect +S, -S, and CS (Current Share) pins in parallel.
- The total output current must not exceed the value determined by the following equation: (Output current at parallel operation) = (Rated output per unit) × (Number of unit) × 0.9.
- For parallel operation with 3 units or more, consult the manufacturer for specific applications.
- Ensure remote sensing wires are kept at least 10 cm from input wires.
- Under parallel operation, the "output voltage trim" function is not available.
- When in parallel operation, the minimum output load should be greater than 3% of total output load (Min. Load >3% rated current per unit × number of unit).
6.5. OLP Select (Overload Protection)
The OLP (Overload Protection) mode can be selected by modifying the connector on CN3.
Figur 6.5: OLP Mode Selection. This section of the image shows two diagrams: one for removing the shorting connector on CN3 for "constant current limiting" OLP mode, and another for inserting the shorting connector on CN3 for "constant current limiting with delay shutdown after 5 seconds" OLP mode.
- Removing the shorting connector on CN3: The O.L.P. mode will be "continuous constant current limiting".
- Inserting the shorting connector on CN3: The O.L.P. mode will be "constant current limiting with delay shutdown after 5 seconds, re-power on to recover".
7. Vedligeholdelse
Regular maintenance ensures the longevity and reliable operation of your power supply.
- Rensning: Periodically clean the exterior of the unit and ventilation openings with a soft, dry cloth. Ensure the power supply is disconnected from all power sources before cleaning. Do not use liquid cleaners.
