Product Overview
Figure 1: Front view of the IOTA DLS-75 Converter Charger. This image displays the robust metallic casing, designed for durability and efficient heat dissipation through its numerous ventilation slots. The power input cord is visible on the left, and the DC output terminals, typically used for connecting to the RV's battery bank, are on the right side of the unit. The IOTA brand logo and DLS-75 model designation are clearly visible on the top label.
The IOTA DLS-75 is housed in a durable, ventilated metal casing designed for efficient heat dissipation. It features clearly marked input and output connections for straightforward installation.
Setup and Installation
Proper installation is crucial for the safe and efficient operation of your DLS-75 converter charger. If you are not confident in your ability to perform the installation, please consult a qualified RV technician or electrician.
Mounting
- Choose a dry, well-ventilated location within your RV or trailer.
- Ensure the mounting surface is sturdy enough to support the unit's weight (approximately 8.8 pounds).
- Mount the unit in a position that allows for adequate airflow around all sides, especially the ventilation slots. Avoid enclosed spaces without proper air circulation.
- Secure the unit using appropriate screws or fasteners through the designated mounting tabs.
Electrical Connections
Before making any electrical connections, ensure that all power sources (shore power, generator, battery bank) are disconnected and secured to prevent accidental re-connection.
- AC Input: Connect the AC input cord of the DLS-75 to a dedicated 120V AC circuit. Ensure the circuit is properly fused or circuit-breaker protected according to local electrical codes.
- DC Output: Connect the DC output terminals of the DLS-75 to your RV's 12V DC distribution panel or directly to your battery bank. Observe correct polarity: positive (+) to positive, and negative (-) to negative. Use appropriate gauge wiring for the 75 Amp output.
- Grounding: Ensure the unit is properly grounded according to all applicable electrical codes.
IQ4 Charge Controller (Optional)
If you are using the optional IOTA IQ4 Charge Controller for advanced four-stage charging, refer to the IQ4's separate instruction manual for connection details. The IQ4 typically connects to a dedicated port on the DLS-75 unit.
Operating Instructions
Powering On
Once all electrical connections are securely made and verified, you can apply AC power to the DLS-75. The unit will automatically begin converting AC power to 12V DC and charging the connected battery bank.
Selectable Charging Modes
The DLS-75 offers two selectable charging modes to optimize battery charging based on your needs:
- 13.6V Mode (Float/Maintenance): This is the standard operating mode, providing a constant 13.6V DC output. It is ideal for maintaining a fully charged battery and powering DC loads in your RV.
- 14.2V Mode (Bulk/Absorption): This mode provides a higher 14.2V DC output, suitable for faster charging of deeply discharged batteries or for absorption charging. Consult your battery manufacturer's specifications for recommended charging voltages.
Refer to the unit's labeling or a specific switch (if present) for instructions on how to select between these modes. If an IQ4 Charge Controller is installed, it will automatically manage the charging stages, including bulk, absorption, and float.
Maintenance
The IOTA DLS-75 is designed for minimal maintenance. However, periodic checks can help ensure its long-term reliability and performance:
- Cleanliness: Keep the unit clean and free of dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
- Ventilation: Regularly inspect the ventilation openings to ensure they are not obstructed. Clear any dust or lint buildup.
- Connections: Periodically check all electrical connections (AC input, DC output) for tightness and corrosion. Loose connections can lead to overheating and poor performance.
- Environment: Ensure the operating environment remains dry and within the specified temperature range.
No user-serviceable parts are inside the unit. Do not attempt to open the casing. Refer all servicing to qualified personnel.
