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.

5. Operasi
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.
| Logik SW | Output dimatikan | Output pada |
|---|---|---|
| SW Terbuka | SW Tutup | SW Terbuka |
Gambar 5.1: Cthamples of connecting remote ON/OFF.
5.2 Output Isyarat Penggera
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.
| Fungsi | Penerangan | 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-Power OK | Rendah (0.5V maks pada 500mA) | Rendah (0.5V maks pada 10mA) |
| The signal turns to be "High" when the power supply is under 80% of the rated output voltage-Power Fail | Tinggi atau terbuka (Jilid yang digunakan luarantage, maksimum 500mA.) | Tinggi atau terbuka (Jilid yang digunakan luarantage, maksimum 10mA.) |
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 Keluaran Voltage Potong
Keluaran 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 is trimmed up.
Figure 5.3: Output voltage trimming characteristics.
5.4 Perkongsian Semasa
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".
