CRISTEC - DC/DC Converter/Charger - DCPOWER+ 12V/36V - 15A

The CRISTEC DCPOWER+ 12V/36V - 15A is a DC/DC converter-charger designed to power or recharge a 36 V battery bank from a 12 V DC power source. It can function as a simple converter, a smart battery charger, a booster, or a stabilized power supply, depending on the system configuration.

It is particularly well-suited for boats with a 12 V onboard electrical system where equipment or a battery bank operates at 36 V. It also allows for the recharging of LiFePO4 batteries from a lead-acid battery connected to an alternator.

Smart and customizable charging.

The DCPOWER+ offers a charge curve that can be configured via the settings button, the Bluetooth interface, or the CAN bus-. It is compatible with various types of batteries, including:

• Sealed lead-acid.
• Gel.
• AGM.
• --calcium lead-acid.
• LiFePO4.
• Other technologies available upon specific request.

The charging profile can operate in up to 5 stages:

• Boost: rapid battery charging.
• Absorption: continued charging up to 100%.
• Floating: charge maintenance.
• Refresh: automatic phase designed to limit sulfation and revitalize the batteries.
• Reboost: a new Boost phase if the battery’s condition or DC loads require it.

Silent operation.

Cooling is provided by natural convection, without a fan, allowing for completely silent operation. The noise level specified by CRISTEC is 0 dB. This design makes it possible to install the unit near living areas on board.

Bluetooth and remote control.

The charger features Bluetooth Low Energy (BLE) as well as CAN-Bus communication. The charging curve can thus be configured locally or remotely.

Designed for marine installations.

The DCPOWER+ operates at its rated load up to +60 °C. At-temperatures above +65 °C, the current is limited to protect the device. The circuit board is also treated with a water-repellent varnish suitable for marine environments.

The models are protected against:

• Polarity reversal.
• Short-circuits.
• Abnormal overheating.

They are also ISO 8846 / SAE J1171 certified for protection against ignition of flammable gases, which allows them to be installed in the engine room.
