(1PCS) 18018/400VLT NEW Transformer

​1. In Home Inverters (The Main Use)

​In brands like Microtek or Luminous, this transformer acts as a “Sensor.” * Example: When your inverter is running your fans and lights during a power cut, it needs to make sure the voltage stays exactly at 220V–230V. This small 18-0-18 transformer “samples” the high voltage and tells the circuit board (PCB) to speed up or slow down so your appliances don’t get damaged.

​2. In Music Systems (Audio Amplifiers)

​If you have a large speaker system or home theater, it needs a “Dual Power Supply” to work properly.

• ​Example: The 18-0-18 transformer provides a +18V line and a -18V line. This “Push-Pull” power allows the speakers to move back and forth perfectly, creating loud and clear sound without distortion.

​Summary in Simple Terms:

• ​In Inverters: It acts like a “Speedometer” to monitor and control voltage.
• ​In Amplifiers: It acts like a “Fuel Pump” to give balanced power for loud music
