| 4 | DC OUTPUT -V (Negative DC Output) |
| 5 | DC OUTPUT +V (Positive DC Output) |
4. Configuración e instalación
Follow these steps for proper installation of the power supply.
- Montaje: Mount the power supply in a well-ventilated area. Ensure sufficient clearance around the unit for proper air convection. The unit can be mounted horizontally or vertically, but consider the airflow direction for optimal cooling. Refer to the mechanical specifications for mounting hole dimensions (Figure 3.3).
- Entrada de cableado (CA):
- Connect the AC Live wire to the 'L' terminal (Pin 1).
- Connect the AC Neutral wire to the 'N' terminal (Pin 2).
- Connect the Frame Ground wire to the 'FG' terminal (Pin 3). This connection is critical for safety.
- Ensure all input wires are securely fastened and have appropriate gauge for the current draw.
- Salida de cableado (CC):
- Connect the positive (+) load wire to the '+V' terminal (Pin 5).
- Connect the negative (-) load wire to the '-V' terminal (Pin 4).
- Verify correct polarity before connecting to the load device.
- Ensure all output wires are securely fastened and have appropriate gauge for the current draw.
- Volumentage Ajuste: El volumen de salidatage can be finely adjusted using the 'V ADJ' potentiometer located near the output terminals. Use a non-conductive screwdriver for adjustment. No exceda el volumen especificadotage rango.
- Comprobación final: Before applying power, double-check all wiring connections for correctness, security, and proper insulation.
5. Instrucciones de funcionamiento
Once the power supply is correctly installed and wired, it is ready for operation.
- Encendido: Apply AC power to the input terminals. The green LED indicator on the unit will illuminate, indicating that the power supply is active and providing output voltage.
- Vol de salidatage: The power supply will provide a stable 24V DC output. If adjustment is needed, refer to the "Voltage Adjustment" step in the Setup section.
- Conexión de carga: Connect your DC load device to the output terminals, ensuring correct polarity.
- Escucha: Observe the LED indicator. If it is off, check the input power and connections.
5.1 Derating Curve and Static Characteristics
The performance of the power supply can be affected by ambient temperature and input voltage. Refer to the following curves for optimal operation.
Figure 5.1: Derating curve showing load percentage vs. ambient temperature, and static characteristics showing load percentage vs. input voltage.
- Curva de reducción de potencia: Shows the maximum permissible load at different ambient temperatures. For temperatures above 50°C, the output power must be derated to prevent overheating.
- Características estáticas: Illustrates how the output load capacity is maintained across the input voltage rango.
6. Mantenimiento
The LRS-35-24 power supply is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Limpieza: Ensure the ventilation holes are free from dust and debris. Use a soft, dry brush or compressed air to clean the unit if necessary. Do not use liquid cleaners.
- Comprobaciones de conexión: Periodically inspect all input and output wiring connections to ensure they remain secure. Loose connections can cause intermittent operation or overheating.
- Condiciones ambientales: Verifique que el entorno operativo permanezca dentro de los rangos de temperatura y humedad especificados.

7. Solución de problemas
Esta sección proporciona soluciones a problemas comunes que puede encontrar.
| Problema | Posible causa | Solución |
|---|---|---|
| Sin volumen de salidatage / LED off | Sin entrada de alimentación de CA Conexiones de cableado sueltas Fallo interno | Verifique la fuente de alimentación de CA y el disyuntor. Verifique que todas las conexiones del cableado de entrada y salida estén seguras. If power is present and connections are good, the unit may be faulty. Contact support. |
| Vol de salidatage fluctuates or is incorrect | Condición de sobrecarga Faulty load Volumentage adjustment potentiometer disturbed | Reduce the load to within specifications. Disconnect the load and test the power supply independently. Carefully adjust the 'V ADJ' potentiometer to the desired voltage. |
| La unidad está excesivamente caliente | Ventilación insuficiente Condición de sobrecarga Alta temperatura ambiente | Ensure adequate airflow around the unit. Clear any obstructions. Reduce the load. Check the derating curve (Figure 5.1). Si es posible, traslade la unidad a un entorno más fresco. |
| Audible noise from unit | Funcionamiento normal (ligero zumbido) Overload or fault condition | A slight hum can be normal. If noise is loud or unusual, check for overload. Disconnect power and contact support if noise persists and is concerning. |
