4. Enstalasyon ak Enstalasyon
4.1 Tcheke Pre-Enstalasyon
Before installation, ensure the power supply is undamaged and that all necessary components are available. Verify the input voltage requirement of your application matches the power supply's capabilities.
4.2 AC Antre Voltage Seleksyon
The LRS-350-24 features an AC input range selectable by a switch. Locate the switch on the side of the unit. Set it to either 115VAC (for 90-132VAC input) or 230VAC (for 180-264VAC input) according to your local mains voltage. Failure to set this correctly can result in damage to the unit.
4.3 Koneksyon fil elektrik
Connect the power supply using the screw terminal block. Refer to the mechanical specification diagram for terminal assignments.
- Antre AC: Connect Live (L), Neutral (N), and Ground (FG) to the corresponding input terminals.
- DC Sòti: Connect the positive (+) and negative (-) load wires to the DC OUTPUT terminals.
Figure 3: Mechanical dimensions and terminal block assignments for the LRS-350 series. This diagram provides physical measurements and pinout details for wiring.
4.4 Montaj
Mount the power supply in a location that allows for adequate airflow around the unit, especially near the cooling fan. Use appropriate screws and mounting points as indicated in the mechanical specification diagram.
5. Operasyon Enstriksyon
5.1 pouvwa sou
After ensuring all connections are secure and the AC input voltage switch is correctly set, apply AC power. The LED indicator on the unit will illuminate, indicating that the power supply is operational.
5.2 Sòti Voltage Ajisteman
Vol la pwodiksyontage can be finely adjusted using the potentiometer located near the output terminals. Use a small screwdriver to carefully turn the potentiometer to achieve the desired output voltage within the specified range (typically 21.6V to 28.8V for the 24V model).
5.3 Operasyon Vantilatè Refwadisman
The built-in cooling fan operates with ON-OFF control, activating automatically when the internal temperature reaches a certain threshold to maintain optimal operating conditions. It will turn off when the temperature drops.
6. Antretyen
The LRS-350-24 power supply is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Netwayaj: Ensure ventilation openings are free from dust and debris. Use a soft, dry cloth or compressed air to clean the exterior. Do not use liquid cleaners.
- Koneksyon: Periodically check all wiring connections to ensure they remain tight and secure.
- Anviwònman: Maintain the operating environment within specified temperature and humidity ranges to prolong the unit's lifespan.
