ATURE Digital power switching increases versatility and cuts costs D
igital power switching can replace expensive and bulky switch panels and reduce cable lengths
in the electrical systems for vessels and vehicles such as agricultural equipment, construction vehicles, boats and industrial machinery. James Cope of Veethree Technologies outlines the advantages of these increasingly popular systems. Conventional elect rical power syst ems in boats and vehicles can be simplified as well as made more flexible with the adoption of digital power switching
systems. Whereas simple s witches requir e individual cabling to each of the devices they control, using a digital swit ching sy stem over a net work such as CAN bus reduces the amount a cabling required while increasing the funct ions t hat can be supported. Being programmable, a digital power distribution system can be easily configured for the part icular load types, breaker/fuse loads etc required, and for the design and functionality of the display. Data from different syst ems can be int egrated and centralised, ensuring important information is available at a glance.
One such DC digital power switching >>>>
module is the VeeConnect from Veethree T echnologies. Each of its 12 channels is capable of supplying up t o 20 A and is fully configurable, including options such a s fuse rating, analogue or digital inputs, and switch ty pe (slider, on/off, burst ). A library of predefined icons and switch descriptions is also available.
With IP 67 all-round protection, the module can wit hstand t he harshest of environments whether it is being used in marine, utility vehicle or industrial applications. It was developed in
conjunction with an aerospace company experienced in handling DC loads on aircraft, where reliability is essential. When used with Veethree’s new T7i 7 inch display, for example, t he display can be configured t o show any combination of button colours or shape, background design, icons and gauge ty pes. Switches can be easily renamed and configured, including assigning the circuit ’s trip current, the power on stat e, and if they are standard, PWM or reversing loads. Switch icons can also easily be assigned and OEMs can go a stage further with fully customised display designs. Examples of the equipment that can

be controlled in marine applications include lights, alarms, engine fan, depth sounder, bilge pump, blowers, horn and entertainment sy st ems. For off-road vehicles, typical uses might be telemat ics, digital and analogue sensors, rear view cameras, engine
management, winches and GP S speed. As t he components are modular, additional equipment can be added as required.
