4. Namestitev in povezave
Proper installation is crucial for the safe and efficient operation of the RSP-3000-24. Follow these guidelines for connecting the power supply.
4.1 Three-Phase Connection
The RSP-3000-24 can be configured for various 3-phase power systems. Refer to the diagrams below for proper wiring.
Figure 4.1: 3-phase 3-wire 220VAC system connection.
Figure 4.2: 3-phase 4-wire 220/380VAC system connection.
Figure 4.3: 3-phase 4-wire 190/110VAC system connection.
5. Delovanje
5.1 Remote ON/OFF Control
The power supply features a remote ON/OFF control function, available by applying voltage in CN1 & CN2 & CN3. Refer to the table and diagrams for connection methods.
| Logika SW | Izhod izklopljen | Izhod vklopljen |
|---|---|---|
| SW Odpri | JZ Zapri | SW Odpri |
Slika 5.1: Npramples of connecting remote ON/OFF.
5.2 Izhod alarmnega signala
The alarm signal is sent out through 'P OK', 'P OK GND' and 'P OK2 & P OK GND2' pins. An external voltage source is required for this function. The table below explains the alarm function built-in the power supply.
| funkcija | Opis | Izhod alarma (P OK, relejski kontakt) | Izhod alarma (P OK2, signal TTL) |
|---|---|---|---|
| P OK | Signal je "nizek", ko je napetost napajanja nad 80 % nazivne izhodne glasnosti.tage-Power OK | Nizka (največ 0.5 V pri 500 mA) | Nizka (največ 0.5 V pri 10 mA) |
| Signal postane "visok", ko je napetost napajanja pod 80 % nazivne izhodne glasnosti.tage-Power Fail | Visoka ali odprta (zunanji uporabljeni zvtage, 500 mA max.) | Visoka ali odprta (zunanji uporabljeni zvtage, 10 mA max.) |
Table 5.1: Explanation of alarm.
Figure 5.2: Internal circuit of P OK (Relay, total is 10W) and P OK2 (Open collector method).
5.3 Izhod Voltage Obrezovanje
Izhodna voltage can be trimmed using an external 1-6V signal connected to the PV pin (PIN3) and PS pin (PIN4) of CN1 or CN2. The power supply must be disconnected if the "Output Voltage TRIM" function is used. Adjustment of output voltage is possible between 20-110% (Typ.) of the rated output which is shown in the figure below. Reducing output current is required when the output voltage je obrezan.
Figure 5.3: Output voltage trimming characteristics.
5.4 Trenutna skupna raba
Parallel operation is available by connecting the units as shown in the diagram. The voltage difference among each output should be minimized to less than 0.2V. The total output current must not exceed the value determined by the following equation: (Output current at parallel operation) = The rated current per unit × number of unit × 0.9. For parallel operation with 3 units, please consult the manufacturer for other applications. Wires of remote sensing should be kept at least 10 cm from input wires. When in parallel operation, the minimum output load should be greater than 3% of total output load. The "output voltage trim" function is not available in parallel operation.
Figure 5.4: Current sharing connection diagram.
5.5 Overload Protection (OLP) Mode
The RSP-3000-24 offers different Overload Protection (OLP) modes. Removing the shorting connector on CN3 (as shown in Fig 5.5) sets the O.L.P. mode to "continuous constant current limiting". Inserting the shorting connector on CN3 (as shown in Fig 5.6) sets the O.L.P. mode to "constant current limiting with delay shutdown after 5 seconds, re-power on to recover".
