Overdraw the outlets - they shut down momentarily

[Big Kahuna]

Learned something new today. Was running some ham radio gear and had a 120v to 12v plugged into the console outlet and radio equipment was drawing 6 to 10 amps I suspect.

I was talking and radio and power supply shut down then 5 seconds later came back on. When radio pulled too much power it would turn off the outlet hen come back on.

I was surprised as I thought it would blow a fuse if too much draw but it just pauses momentarily.

I wonder what type of system can do that?

I turned down radio output and it didn’t do it again but did test it 4-5 times and each time it shut off then came back on.

Automatic reset circuit breakers?

I's guess the Inverter may use overload circuit like the BCM.

Field Effect Transistor (FET) Protection
The BCM utilizes a Field Effect Transistor (FET) protective circuit strategy for many of its outputs, for example, lamp output circuits. Output loads (current level) are monitored for excessive current (typically short circuits) and are shut down (turns off the voltage or ground provided by the module) when a fault event is detected.
A FET is a type of transistor that the control module software uses to control and monitor current flow on module outputs. The FET protection strategy prevents module damage in the event of excessive current flow.

DC/AC INVERTER AND AC POWER POINT

The DC - AC inverter has a self-protection feature for the following conditions:
• Short circuits on the inverter output circuits: If the inverter detects a short on the output circuit(s), it shuts down. After 6 seconds, it restarts and checks for a short condition. If the condition still exists, the inverter shuts down again. The inverter restarts 5 times and, if the short still exists on the 5th restart the inverter disables AC output and flashes the LED indicator.
• Low voltage input: The inverter does not operate when the input voltage is less than 11 volts.
• High voltage input: The inverter does not operate when the input voltage is greater than 16 volts.
• Overload
• High temperature: The inverter does not operate if it has overheated or if ambient (cabin) temperatures exceed 75 C (167 F).
If the self-protection feature is activated, the LED indicator flashes and the DC - AC inverter does not provide power output to the AC outlet. If the LED is flashing, the problem must be corrected before DC- AC inverter operation will resume.

TIL: When the inside of your truck reaches the safe cooking temperature for chicken you might need to worry about a non-functional inverter. Good to know. Better make a mental note.

High temperature: The inverter does not operate if it has overheated or if ambient (cabin) temperatures exceed 75 C (167 F).

Interesting. It pretty cool if it’s that smart. Better than having to replace fuses.
