PBUS System

Energy Management Box

The EM-Box is an innovative power management marine product which optimises efficiency in a boat's power creation and storage capacities. The product is a single solution to a number of different power management challenges and is energy, environmentally and economically efficient. Different batteries have different charging needs. The EM-Box detects what these needs are and delivers what is required. This prolongs the batteries' lives, minimising environmental impacts and regular replacement expense for the boat owner. Boat electrical systems have multiple points of failure, with many connections, fittings and wirings which are responsible for 80% of electrical system failures. The EM-Box simplifies the installation and reduces potential failures. The circuit boards and connections are localised in a single watertight box, which is the size of a shoe box. This makes installation and fault finding extremely flexible and easy. The EM-Box optimises a boat's power generation, including power from generators and alternators as well as solar and wind. This gives greater flexibility to power creation methods, will benefit the environment and will cause reduced running costs to the user.

If the EM-box is used without the system monitor PSM, the battery disconnect switches can be controlled with standard toggle switches 0-1 from any desired location. The charging characteristic are pre defined to temperature compensated IUoU-characteristic to 14,4 V/13,8 V @ 20°C.

EM-box Embox

The Energy Management Box reduces the high-current wiring around the engine and battery system to a minimum. It handles the complete charging and energy management of a modern single engine yacht or a expedition vehicle with up to 3 battery groups (starter, house and bow batteries) and additional alternative charging sources (solar, wind and hydrogen generators). Even the DC connection of a combi inverter is taken into account.

The EM-box combines:

  • 10 high power shunts
  • Charging distributor for the alternator
  • 3 remote controlled battery main switches
  • Deep discharge protection
  • Charge current distribuction for battery charger, solar panels, wind generator, hydro generator
  • Negative busbar
  • Main protection of the electrical on board system
  • Engine emergency start from house battery
  • Manual emergency switching of the main switches
  • P-Bus Interface for System-Monitor PSM2/PSL
The EM-box enables:
  • Easy and clearly arranged installation
  • Less error sources
  • Safety due to separate positive and negative connections
  • Reduced space requirement
  • Immediate operation without configuration
  • Low installation costs
  • Battery monitoring for all battery banks
  • Remote control of the main switches
  • Clear DC energy balance
  • Use for 24 V electrical systems
