Mean Well Switching Power Supply - 12V, 55W#
 |
Mean Well Switching power supply 12V 55W ensures uninterrupted powering of MikroTik RouterBoards or other devices demanding the voltage of 12V. 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.
Features:#
- Universal AC input / Fullrange
- Protections: Short circuit / Overload / Overvoltage
- Battery low protections
- Cooling by free air convection
- 100% full load burn-in test
- Fixed switching frequency at 45KHz
- With UPS function (need external batteries)
- Suitable for security industry or battery backup systems
