What protections does the PowerBlock 120W Inverter have?

PROTECTIONS

Overload and short circuit on the AC output side

  • If the load exceeds 120W, the output voltage will start dropping, but the unit will
    not shut down.
  • The LED Status Indicator will remain GREEN.
  • The output voltage waveform will be distorted and will not have pure sine waveform,
    but will be clipped at top and bottom and will look like a square waveform.
  • There will be excessive RF noise.
  • The until will reset automatically once the overload/short circuit is removed.

Over temperature due to fan failure or due to lack of cool replacement air

  • The unit will shut down if temperature of hot spot inside the unit > 105°C. The LED
    Status Indicator will turn Orange.
  • The unit will reset automatically on cooling.

Low DC Input Voltage

  • The unit will shut down if DC input voltage is < 10 VDC.
  • The LED Status Indicator will turn Orange.
  • The unit will reset automatically when the voltage rises to 11.5 VDC.

High DC Input Voltage

  • The unit will shut down if DC input voltage > 16.5 VDC.
  • The LED Status Indicator turns Orange.
  • The unit will reset automatically when voltage is < 16.5 VDC.

Over Voltage On USB Port

  • USB output is shut down if USB output ≥ 6.2 VDC.
  • The LED Status Indicator will be OFF or RED.
