PRODUCT OVERVIEW
The iTECHDCDC60 charger is suitable for charging all common types of automotive or recreational 12-volt lead-acid batteries such as Standard Lead Acid, Gel, AGM, and Calcium, or LiFePO4 (Lithium Iron/Ferro Phosphate) Chemistry 12-Volt Lithium batteries. It can operate on both 12- and 24-volt alternators, as well as unregulated 12-volt nominal solar input. Notably, the iTECHDCDC60 features a Maximum Power Point Tracking (MPPT) solar regulator, which maximises power harvested from connected solar panels, thus increasing charging efficiency.
Designed with high efficiency in mind, the iTECHDCDC60 charger is compact and suitable for installations with limited space. Additionally, it is engineered to isolate the auxiliary battery from the cranking battery, preventing over-discharge of the cranking battery.

BATTERY CHARGING PROFILE:
To modify the battery charging profile, press the 'Mode' button for 1.5 seconds. As a result, the battery type indicator will move one LED to the right. Please be aware that following any changes, there might be a delay of up to 2 minutes before the charger starts the charging process.
LED CHARGE INDICATOR

|---|---|---|
| Short flash GREEN | Solid GREEN | Bulk or Absorbtion |
| Long flash GREEN | Solid GREEN | Float |
UNIT OPERATION
When the iTECHDCDC60 is connected, all LED indicators will light up, indicating normal operation. The charger is initialising and will take up to 2 minutes to start charging. The iTECHDCDC60 will go into standby mode if the input voltages are below the turn-off voltage. It will continue to charge the auxiliary battery for up to 2 minutes before going into standby, indicated by the charge input and battery type indicator LEDs blinking momentarily. Once charging voltages rise above the cut-in voltage, it will take up to 2 minutes for the charger to "wake" and begin to charge.
The iTECHDCDC60 will start to charge from solar input if the panel supply voltage is above 15V and outputting at least 30W (2 Amps).

INSTALLATION
INSTALL LOCATION:
The iTECHDCDC60 charger has been designed for installation in a variety of locations. If the charger is to be installed in the vehicle cabin, please ensure there is adequate ventilation around the charger, and that it is not installed in an enclosed space where airflow is restricted. The temperature of the charger case can typically be 20-30 degrees Celsius above ambient temperature; it is normal for the charger to feel hot and for you to not be able to keep a finger on the surface for more than a couple of seconds as the case can exceed 60 degrees Celsius.
The iTECHDCDC60 charger should be installed as close as possible to the auxiliary battery; this allows for more efficient charging of your auxiliary battery. The iTECHDCDC60 can be mounted with 4 screws (not included); there are mounting brackets where the screws can be affixed.
[Image Description: A top-down view schematic of the iTECHDCDC60 charger, showing its dimensions: 317.5mm in length and 170mm in width. The charger has a robust, ribbed casing and the iTECHWORLD logo is visible.]
SELECTION OF CABLE SIZE:
For 12V input and output connections, it's advisable to use ring terminals. In general, using thicker wire sizes will enhance performance, while using thinner wires may diminish performance, particularly when they are too small for the application. When contemplating your wiring choices, prioritise thicker and shorter wire lengths to minimise resistance and voltage drop.
| Input | Length | ||
|---|---|---|---|
| 0-3M | 3-6M | 6-9M | |
| Solar Positive Alternator Positive Output Positive Ground | 16mm² (6AWG) | 25mm² (4AWG) | 25mm² (4AWG) |
| Ignition | 0.5mm² (20AWG) | 0.5mm² (20AWG) | 0.5mm² (20AWG) |
iTechworld strongly advises that a properly trained / qualified individual conducts this task. Failure to establish a secure connection could result in a short circuit, potentially leading to fire and property damage.
[Diagram Description: A diagram illustrating a potential short circuit scenario with wires, a crimp connection, and solder. It highlights the risk of fire and property damage from improper connections.]
For wire extensions, it is advisable to utilise soldered butt splice connectors. This ensures minimal resistance in the connections. The optimal approach is to crimp both ends of the connector, followed by soldering both sides of the connector. Once the connection is secured, it is crucial to employ heat shrink tubing to protect the connections and prevent any potential short circuits.

WIRING:
Before any connections are made during installation, please disconnect the main cranking battery to prevent any short circuits. Please note down any radio anti-theft codes before the battery is disconnected.
[Diagram Description: A diagram showing the rear connection terminals of the iTECHDCDC60 charger, labeled ALT+, GND, PV+, GND, BAT+, IGN. Arrows indicate connections to three components: "Cranking Battery" (labeled 2), "Solar Panel" (labeled 3), and "Auxiliary Battery" (labeled 1).]
Output: connects to the battery being charged (the auxiliary battery). [1]
Alternator Input: connects to the main cranking battery. [2]
Solar Input: connects to an unregulated solar panel. [3]
The ignition: connects to a switched ignition source (i.e., a point that supplies 12V only when the key is in the 'ON' position and disconnects when the key is in the 'OFF' position). This can be found by tapping into the vehicle's accessory wiring or the vehicle's fuse box, and a fuse tap can be used.
TYPICAL SETUP:
[Diagram Description: A wiring diagram illustrating a typical installation setup. The iTECHDCDC60 charger is shown connected to a "Start Battery" (cranking battery) and a "To Auxiliary Battery". A "Solar Panel" is also connected to the charger. Fuses are placed in series with the positive connections to the start battery and auxiliary battery. The ignition wire connection is shown with two options: "For Vehicle with Smart Alternator: Connect to Switched Ignition Source" and "For Vehicle with Standard Alternator: Leave Unconnected". An "Optional Connect with Remote Panel" is also indicated.]
FUSE SPECIFICATIONS:
It is essential to install all recommended fuses in series within the circuit. Bolt-down fuses are the preferred choice as they guarantee a low-resistance connection. In contrast, blade-type fuses are not recommended because they can lead to a high-resistance connection, potentially causing excessive heat and potential damage to the fuse holder and wiring. Additionally, self-resetting circuit breakers are discouraged because they may trip prematurely due to the heat generated by the current flowing through the wires.
