Detailed description

The MLI Ultra Connection Kit 12 V from Mastervolt is an integrated solution designed to secure the installation of MLI Ultra 12 V lithium-ion batteries. This kit centralizes essential safety accessories, making them compact and easy to mount directly above the battery, reducing clutter and wiring complexity. Unlike traditional installations that require separate component mounting, this kit provides a pre-engineered solution that ensures optimal integration and compliance with Mastervolt performance standards.

Integration and Compatibility

This kit is specifically compatible with Mastervolt MLI Ultra 12 V batteries, including models MLI Ultra 12-2750, MLI Ultra 12-5500, MLI Ultra 12/3000, and MLI Ultra 12/6000. It integrates a 12 V DC, 500 A safety relay, ensuring reliable protection of the electrical system. The pre-assembled design on a dedicated mounting bracket facilitates quick installation without complex electrical tools, positioning this kit as a preferred option for efficient and secure implementation of onboard energy management systems.

Advanced Technical Features

The MLI Ultra Connection Kit 12 V is engineered for robust performance, supporting a maximum continuous current of 300 A and a maximum voltage of 64 V. It operates within an extended temperature range, from -25 °C to 50 °C (-13 °F to 122 °F). The kit includes a T-type fuse holder compatible with 225 A to 400 A fuses (the fuse itself is not supplied and must be sized according to the application), a safety relay, and two conductive busbars. This device increases the battery's total height by 65 mm (2.5 inches) and its total weight by 2 kg (4.4 lb). It complies with European directives EMC 2014/30/EU and RoHS 2011/65/EU (as amended by 2015/863), attesting to its compliance with electromagnetic compatibility and hazardous substance restriction standards.

« MLI Ultra 12V Connection Kit: secure integration by Mastervolt »

The Mastervolt MLI Ultra Connection Kit 12 V is an essential component for any professional installation of MLI Ultra 12V lithium-ion batteries. Its integrated design, combining a 500 A safety relay and a T-type fuse holder, significantly simplifies wiring and the integration of protection devices. This centralization reduces the risk of installation errors and optimizes space usage, a major advantage in the confined spaces of vessels. The 65 mm height increase and 2 kg weight increase are a reasonable trade-off for the benefits in terms of safety and installation cleanliness.

Compatibility with the MLI Ultra 12-2750, 12-5500, 12/3000, and 12/6000 ranges ensures a dedicated and high-performance solution. The 300 A continuous current capacity and maximum 64 V voltage confirm its robustness for demanding marine applications. Compliance with EMC and RoHS directives attests to its reliability and adherence to environmental and electromagnetic standards, crucial for the longevity and safety of embedded systems. As an integrator, we value the ease of installation and the guarantee of optimal protection this kit provides, minimizing post-installation interventions.
