1. Introduction

This manual provides essential information for the safe and effective installation, operation, and maintenance of the REDARC DPS2420 24V 20A In-Vehicle DC Power Supply. The DPS2420 is designed to deliver efficient, regulated 24V DC power to various sensitive electrical loads within a 24V automotive system. It is suitable for powering devices such as lamps, televisions, radios, refrigerators, and pumps.

The unit features a robust design, reduced operational noise due to its fan-free operation, and built-in protection against electrical spikes and surges. Its fully encapsulated construction makes it suitable for use in demanding environments, including marine applications.

2. Safety Information

Adherence to the following safety guidelines is crucial for preventing injury and damage to the product or vehicle:

• Always disconnect the vehicle's battery or power source before attempting any installation or maintenance.
• Ensure all wiring connections are secure and correctly polarized to prevent short circuits or electrical hazards.
• Install the unit in a well-ventilated area, away from flammable materials.
• Do not expose the unit to excessive moisture or extreme temperatures beyond its specified operating range.
• Consult a qualified automotive electrician for complex installations or if you are unsure about any aspect of the installation process.
• Adhere to all local electrical codes and regulations applicable to in-vehicle electrical installations.

3. Setup and Installation

Proper installation is vital for the optimal performance and longevity of the DPS2420. The unit's robust and flexible design allows for various mounting options.

3.1 Mounting

Select a secure, flat surface for mounting the power supply. Ensure adequate clearance around the unit for air circulation, despite its fan-free design. Use appropriate fasteners to secure the unit firmly to prevent movement during vehicle operation.

3.2 Wiring Connections

1. Input Power: Connect the input terminals of the DPS2420 to a stable 24V DC automotive power source. Ensure the wiring gauge is appropriate for the expected current draw (up to 20A) and protected by a suitable fuse or circuit breaker. Observe correct polarity.
2. Output Power: Connect the output terminals of the DPS2420 to the devices requiring regulated 24V DC power. Again, ensure correct polarity and use appropriate wiring gauge for the connected loads.
3. Grounding: Ensure a solid ground connection for the unit to the vehicle chassis.

The DPS2420 is designed with built-in protection against spikes and surges, contributing to the safety of connected equipment. Its fan-free operation ensures reduced noise, preventing interference with sensitive electronic systems like high-tech radio equipment.

4. Operating Instructions

The REDARC DPS2420 operates automatically once correctly installed and connected to a 24V automotive power system. It provides a stable and regulated 24V DC output to all connected loads.

• Power On: Once the input power is supplied, the unit will automatically begin regulating and supplying power.
• Indicator Lights: Refer to any indicator lights on the unit (if present) for status information. (Note: Specific indicator light functions are not detailed in the provided product description, refer to product labeling if available).
• Fan-Free Operation: The unit operates silently without a fan, making it suitable for noise-sensitive environments.

Ensure that the total current draw of all connected devices does not exceed the unit's maximum output of 20 Amps.

5. Maintenance

The REDARC DPS2420 is engineered for durability and requires minimal maintenance.

• Periodic Inspection: Periodically inspect all wiring connections to ensure they remain secure and free from corrosion.
• Cleaning: Keep the exterior of the unit clean and free from excessive dirt, dust, or debris. Use a dry cloth for cleaning. Do not use harsh chemicals or abrasive cleaners.
• No User-Serviceable Parts: The unit contains no user-serviceable parts. Do not attempt to open or repair the power supply, as this will void the warranty and could lead to electrical hazards.

6. Troubleshooting

If you encounter issues with your REDARC DPS2420, consider the following troubleshooting steps:

• No Power Output:
  • Verify that the 24V input power source is active and providing the correct voltage.
  • Check all input and output wiring connections for looseness or incorrect polarity.
  • Inspect any inline fuses or circuit breakers in the input power line for continuity.
• Intermittent Power:
  • Ensure all connections are tight and free from corrosion.
  • Check for loose wires or damaged insulation.
• Overload Protection:
  • If the unit stops providing power, it may be due to an overload. Disconnect some loads and restart the unit (if applicable, by cycling input power).
  • Ensure the total current draw of connected devices does not exceed 20 Amps.

If problems persist after performing these checks, contact REDARC customer support or a qualified technician for further assistance.
