This board uses to regulate motor speed through phase control. Key features include: is this board inside

: The 2021 board update integrates a robust Pi-filter network. This consists of metal-oxide varistors (MOVs) to absorb high-voltage line spikes and a combination of X2-rated film capacitors and a dual-winding common-mode choke coil. This suppresses electromagnetic interference (EMI) from bleeding back into your workshop electrical lines. 2. DC Rectification and Power Stage Key features include: : The 2021 board update

When installing the board, follow the labels on the PCB carefully, as specific board revisions may vary slightly. Terminal Label Main Power Connect 230VAC, 50/60Hz mains. DC Line Output (A+, A-) Motor Armature

Alternating current enters through the terminal blocks designated for Main Line power.
