Same voltage DC DC Converters help keep your electronics running smoothly even with a variable power supply.
Anyone using sensitive electronics in a mobile environment will be familiar with the problem of equipment malfunction caused by a fluctuating power supply. This often happens in Police, Fire or Emergency Vehicles where there is a computer or other similar electronics on board, often connected to other equipment using a CAN BUS network. The engine is started, the voltage drops, and the electronics turn off and reboot. Boaters have the same problem and need a constant power supply for a complicated network of electronics that usually include a chartplotter connected to a NMEA 2000 network.
Orion-Tr 12/12-9A This model has a 110 Watt output (nominal 9 Amps)
Using a Victron Energy Isolated DC DC Converter you can take a variable power input and use it to produce a steady constant voltage power output and avoid all the problems caused by fluctuating voltage. For 12 volt systems there are three models. These isolated DC-DC converters takes an input voltage ranging from 8 to 17 volts and deliver a user adjustable steady output voltage in the range of 10-15 volts. The output voltage stays constant even though the input voltage varies.
Orion-TR 12/12-18A This model has a 220 Watt output (nominal 18 Amps)
Orion-Tr 12/12-30A This model has a 360 Watt output (nominal 30 Amps)
Similar models are available for 24 volt systems. Features shared by these models include short circuit protection, IP43 water protection when mounted in the correct orientation, the ability to fit a remote on-off switch and the ability to parallel them for greater output. All include safety features like built in short circuit protection and high temperature protection. A neat and simple solution to a tricky problem.
