The ArSilicii DCC-530 and DCC-850 are automotive 3-stage smart battery-to-battery chargers designed for use in vehicles. These units are part of the DCC family, which is engineered to charge batteries from a variable DC input source, such as an alternator or another battery, by dynamically adjusting the output to follow a user-selected 3-stage charging cycle. The charging cycle is chosen based on the battery's chemistry and the manufacturer's specifications, ensuring optimal charge levels and maintenance.
The DCC chargers are capable of operating as both a battery charger and a stabilized power supply. When in charger mode, the unit maintains a constant current until the battery voltage reaches the absorption voltage. This current may vary to maintain a safe operating temperature or to limit the difference between input and output voltages. After the absorption stage, the charger enters a float stage, maintaining 13.5V on the output battery to keep it topped up and counteract self-discharging. If the battery loses charge due to excessive loads, the charger will revert to the first stage.
A key feature of the DCC family is its ability to function as a standard step-up or step-down stabilized power supply for a load, even in the absence of an auxiliary battery, drawing energy directly from the alternator. This makes it versatile for various automotive applications. The units are designed to work with modern low-emission vehicles, including those equipped with START and STOP devices, and accept control signals from most major vehicle manufacturers.
To conserve quiescent current when not in use, the unit can be powered only when the ignition is on, or it can operate in an "always ON" mode with a very low quiescent current (<2mA) for critical applications. When turned on, the DCC analyzes the connected load for approximately 20 seconds to detect a battery. If a battery is detected, it switches to CHARGER mode; otherwise, if only a standard load is detected, it switches to STABILIZER mode, delivering all possible power at a steady output of 13.5V.

The unit operates optimally below 55°C air temperature with good airflow. At higher temperatures, it will automatically de-rate output current.
The DCC chargers offer customizable charging cycles and system logic. Pre-set charging cycles can be selected using dip switches on the front panel, supporting various battery types:
Custom charge cycles and system logic can be programmed via a serial communication connection using proprietary software, allowing for specialized applications such as managing batteries with special chemistry, 24V-12V voltage system conversion, power filtering and stabilizing, or solar power conversion/charging.
The units are equipped with four front LEDs to indicate their operational status:
Installation options include 3-wire and 4-wire connections. The 4-wire connection is highly recommended as it separates loads from the leisure battery, allowing the unit to precisely estimate the auxiliary battery's charging status and optimize the charging cycle. Control signals from the vehicle, such as ignition key and engine running signals, can be connected to enable or disable the unit and adaptive charging. Adaptive charging, when enabled, limits the output current to prevent excessive voltage drop on the input line, especially with smaller input cabling.
The DCC-0850 can be controlled and monitored via a communication bus. By default, when used with ArSilicii control panels, the TTK bus is utilized.
The manual emphasizes the importance of proper installation and cabling. All faulty units must be returned to ARSILICII for repair, as altering or disassembling the charger voids the warranty and poses risks of electric shock or fire.
For optimal performance and safety, it is crucial to use appropriate cable sizing. The manual provides a table outlining required cable sizes for given lengths to ensure voltage drop is less than 3%. Good, low-resistance electrical connections are essential to prevent degradation over time, which could lead to insulation breakdown, short circuits, or fire. Crimping and soldering are recommended for secure and long-lasting connections, with heatshrink to prevent accidental contacts.
The DCC chargers are designed for charging Standard Automotive Lead Acid, Calcium Content, Gel, AGM, Deep Cycle, or Lithium Ion batteries. Users must check their battery manufacturer's data to ensure that the selected charging profile's maximum voltage does not exceed the recommended maximum charging voltage. If it does, an alternative profile should be chosen.
Safety precautions include wearing eye and clothing protection when working near a battery and immediately washing off any battery acid contact with soap and water, seeking medical assistance for eye contact. Smoking, sparks, or flames should be avoided near batteries or engines due to the risk of explosion from generated gases.
