5. Setélan
5.1 Ngabongkar sareng Inspeksi
Carefully unpack the power supply and inspect it for any signs of shipping damage. If damage is found, contact your supplier immediately. Retain all packaging materials for future transport.
5.2 Pamasangan
Mount the power supply in a location that allows for adequate airflow and heat dissipation. Ensure that the ventilation openings are not obstructed. Maintain sufficient clearance around the unit as specified in the technical drawings (not provided in this manual).
5.3 Input Power Connection
Connect the AC input power cable to the designated AC input terminals on the power supply. Ensure proper grounding by connecting the ground wire to the protective earth terminal. Verify that the input voltage and frequency are within the specified range (Universal AC input).
5.4 Sambungan Kaluaran
Connect the DC output cables to the load, observing correct polarity. The positive (+) output should connect to the positive terminal of the load, and the negative (-) output to the negative terminal of the load. Use appropriately sized cables to handle the maximum output current.
5.5 Remote Control Connections
For remote operation, connect the RS232, RS485, or I²C communication cables to the respective ports on the power supply and your control system. Refer to the detailed communication protocol documentation (not provided in this manual) for specific wiring and command structures. Connect remote sense lines to the load for improved voltage regulation at the point of load.
6. Parentah Operasi
6.1 Powering on / Pareum
After all connections are securely made, switch on the AC input power. The power supply will perform a self-test. To power off, switch off the AC input power.
6.2 Setting Output Voltage jeung Ayeuna
Kaluaran voltage and current can be set either locally via the front panel controls (if available) or remotely via the communication interfaces (RS232, RS485, I²C). Refer to the programming guide (not provided in this manual) for detailed instructions on remote programming commands. The output voltage and current are programmable from 0% to 105% of their nominal values.
6.3 Using Programmable Features
Utilize the programmable features to precisely control the output for specific application requirements. This includes setting constant voltage (CV) or constant current (CC) modes, and adjusting parameters dynamically through the remote interfaces.
6.4 Parallel Operation (Current Sharing)
For applications requiring higher current, multiple AEK-3000-12 units can be operated in parallel using the forced current sharing feature. Connect the current sharing lines as per the wiring diagram (not provided in this manual) to ensure balanced load distribution among the units.
