2. Sikkerhedsinstruktioner

WARNING: Risk of electric shock and energy hazard. Installation must be performed by qualified personnel only.

• Ensure the power supply is disconnected from the AC mains before any installation, wiring, or maintenance procedures.
• Kontroller, at input voltage range of the power supply matches your local AC mains voltage. The RSP-2000-48 features universal AC input (90~264VAC).
• Proper grounding is essential to prevent electric shock. Connect the protective earth (PE) terminal to a reliable ground connection.
• Do not operate the unit in environments with high humidity, excessive dust, or corrosive substances. This unit is designed for indoor use.
• Ensure adequate ventilation around the power supply. Do not block the cooling fan or air vents. Maintain sufficient clearance for airflow.
• Åbn ikke strømforsyningen casing. Der er ingen dele indeni, som brugeren kan servicere. Åbning af casing bortfalder garantien.
• Avoid touching live terminals when the unit is powered on.

4. Opsætning og installation

4.1 Montering

• Mount the power supply in a well-ventilated area to ensure proper heat dissipation.
• Ensure sufficient clearance (at least 10-15 cm) around the unit, especially near the fan intake and exhaust.
• Use appropriate screws and mounting hardware to secure the unit firmly to a stable surface.
• The unit can be mounted horizontally or vertically, but ensure the fan is not obstructed.

4.2 Ledningsforbindelser

All wiring must comply with local electrical codes and standards. Use appropriate wire gauges for the expected current loads.

1. AC-indgangsforbindelse: Connect the AC mains (Line, Neutral, Earth) to the designated input terminals. Ensure the Earth terminal is securely connected to a protective ground.
2. DC-udgangstilslutning: Connect the DC output terminals (+V and -V) to your load. Observe correct polarity.
3. Remote Sense (Optional): Til applikationer, der kræver præcis volumentage regulation at the load, connect the remote sense terminals (+S and -S) to the load's positive and negative terminals, respectively. This compensates for voltage drop across the output cables.
4. ON/OFF Control (Optional): The unit features a remote ON/OFF control. Refer to the detailed wiring diagram for specific connections to enable or disable the output remotely.
5. Current Sharing (Optional): For parallel operation of multiple RSP-2000-48 units to increase total output power, connect the current sharing pins (CS) of up to four units. Ensure all units are of the same model and output voltage.
6. Auxiliary Power (Optional): An auxiliary power output may be available for external control circuits. Consult the product datasheet for specifications.

5. Betjeningsvejledning

5.1 Tænd/sluk

• After all connections are securely made and verified, apply AC mains power to the unit.
• The built-in fan will start operating, and the DC OK indicator (if present) should illuminate, indicating stable output voltage.
• To power off, disconnect the AC mains supply.

5.2 Udgang Voltage Adjustment (Vo Trim)

Output voltage can be finely adjusted using an external control signal. Refer to the product datasheet for the specific voltage range and control method (e.g., external potentiometer or DC voltage signal). This allows for precise tuning of the 48V output to meet specific application requirements.

5.3 Monitoring Signals

• DC OK Signal: This signal indicates that the DC output voltage is within its specified operating range.
• Alarmsignal: This signal activates in case of a fault condition, such as over-temperature, over-voltage, eller blæserfejl.

6. Vedligeholdelse

The RSP-2000-48 power supply is designed for high reliability and requires minimal maintenance. However, periodic checks can help ensure optimal performance and extend its lifespan.

• Visuel inspektion: Periodically inspect the unit for any signs of damage, loose connections, or excessive dust accumulation.
• Rensning: If dust accumulates on the fan or vents, gently clean them using compressed air or a soft brush. Ensure the power supply is disconnected from the mains before cleaning. Do not use liquid cleaners.
• Ventilatorbetjening: Listen for any unusual noises from the cooling fan. A failing fan can lead to overheating.
• Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og luftfugtighedsområder.
