This dedicated external power supply adapter is a high-efficiency switching power supply designed to convert an input AC voltage of 100-240V into a stable DC output. It first rectifies and filters the AC input into DC, then converts it back to AC at a high switching frequency. The voltage is stepped down using a transformer, followed by rectification and filtering to provide a clean DC output of 9V at 1A.
Package Includes:
- 1 × Dedicated External PSU Power Supply Adapter (9V 1A)
