Safety Test Requirements
⚠️ The following operations are strictly prohibited:
Keep away from heat sources: It is prohibited to use near fire sources, heaters and other high temperature environments.
Prohibition of AC input: The input line must not be connected to 220V AC (only DC input is supported).
Prohibit fire/heating: The product must not be put into fire or heated.
Avoid short circuit: It is prohibited to short connect the positive and negative terminals with wires or metal objects.
Non-professionals are prohibited from disassembling and repairing: users are not allowed to disassemble or repair the product by themselves.
Test specification
Input compatibility test: verify the output voltage stability in the range of 8-32V (e.g. full load efficiency at 8V input).
