SL-DH-300-121 300W12V Inverter DC to AC,Provide a variety of voltage and power options
Features:
High conversion efficiency and quick start;
Strong load adaptability and stability;
Provide over-current and short-circuit protection to avoid electrical damage;
Built-in fuse, safe and reliable;
Provide low voltage protection; provide overload protection;
Quiet operation, solid and practical appearance, easy to carry;
Main functions and protection:
1. Under-voltage protection (protect the life of the battery): When the battery voltage drops to the set under-voltage point of the machine, the buzzer will alarm and it will automatically stop after one minute.
2. Over-voltage protection: The over-voltage system is automatically closed.
3. Overload protection: Overload delay protection.
4. Overheating protection: when 40℃, the machine will automatically start the fan to dissipate heat; when it exceeds 65℃, it will alarm for one minute and stop; when it exceeds 70℃, it will shut down immediately.
5. Charging protection: constant current and constant voltage charging.
