 24V 55W

 24V 55W
Switching power supply 24V 155W ensures uninterrupted powering of MikroTik RouterBoards or other devices demanding the voltage of 24V. The power supply works with two accumulator batteries 12V/7Ah or 12V/5Ah. In case of power loss the power supply delivers the power from the batteries. When the power comes back the power supply returns to it normal operations and the batteries are recharged automatically.
