LC-EM-1283

Product Name

AC-DC Gallium Nitride Isolation Switch Power Module 40W High Current 220V to 12V

Regarding LC-EM-1283

The LC AC-DC gallium nitride isolation switch power module uses Power Integrations' SC1933C as the main control chip,
which can efficiently AC90-250V@50Hz ~60Hz AC power is converted into stable 12V DC power,
and the input end comes with EMI filtering and lightning protection circuit to prevent mutual interference between the power grid and the switching power supply.
The output end supports three wiring methods: screw post, plug-in, and wire bonding
