Victron Energy DC-DC Converter 9A 12V

Adjustable stabilized output voltage (10-15 volts) for devices that require a constant operating voltage. Suitable for "ground" devices that operate on 12.0 volts, but cannot withstand the engine charging voltage, e.g. certain LED lights, television, 4G router, etc.
Can also be used as a battery charger for trickle charging, e.g. charging a 12V starter battery or an additional battery in the system. Short-circuit protected and can be paralleled to increase output current. Unlimited number of devices can be connected in parallel.

With the remote control, no high-voltage switch is required for the input cables. The remote control can be controlled with a low-voltage switch or, for example, the motor on/off switch. IP43 protection: When the device is installed with the screw fasteners facing downwards.
