New! Victron Orion-Tr Smart 12V-48V 8A DC-DC Charger

Victron Orion-Tr Smart 12/48-8A Isolated DC-DC Charger - ORI124838120:

Victron Orion-Tr Smart DC-DC charger is a professional 3-stage adaptive DC to DC charger with built-in Bluetooth. Suitable for use in dual battery systems in cars or on the boat where the (smart) alternator and start battery are used to charge the service battery. The unit can be programmed and monitored via Bluetooth and can be controlled remotely by remote on/off switch and has an engine running detection.

The Orion-Tr Smart charger can be used in 12V, 24V and 48V systems and can be used on lead acid and lithium batteries. The charger is available in models up to 400W and unlimited multiple units can be paralleled to obtain higher output power. The charger is high temperature suitable up to 55°C with full rated output up to 40°C.

What are the benefits of a 12V - 48V DC-DC Charger?

As Caravan/Camping systems are becoming larger and larger in capacity, some OEM manufacturers are changing over to a 48VDC system from a standard 12V or 24V installation. The advantages of this are lower current at higher voltage, therefore a smaller cable size is required, smaller circuit protection and less overall weight. The disadvantages of this, now it's far harder to charge from your car alternator while traveling. This is due to the fact that most of the products available in the market are made to fit 12V or 24V applications alone.

The Victron Orion-Tr Smart 12/48-8A Isolated DC-DC Charger (ORI124838120) is the ideal solution as it takes a 12V input from your vehicle's start battery / alternator and steps up the voltage to 48V to charge your 48VDC House batteries while on the go. As the unit is stepping up from 12V to 48V, what is happening fundamentally is current is lower on the output but, from a power point of view, the Watts remain equal at about 380W. The same also will be influenced by such factors as: voltage drop, temperature, cable size, state of charge of batteries, internal resistance etc.
