Note: When the main voltage is light or no load, the secondary voltage and independent power supply have no output.
Purchase Note:
1. This product is dangerous for bare boards with high voltage circuits. It must be purchased by people who will use it. This store does not bear all the consequences caused by the use. 2. For commercial purposes, circuit and component grinding and epoxy resin potting, no schematic, pcb 3. For long-term high-power use, please add fan air-cooling, power supply with over-temperature shutdown protection, protection for self-locking protection, you must disconnect AC power and wait a few minutes before re-energizing to start. This power supply is a true LLC resonant power supply. The resonant circuit is a high frequency positive mystery wave. It is not an ordinary square wave switching power supply. It is very suitable for power amplifier use.
