Linear phase-shift control circuit with good stability and high precision

Innovative structure with high efficiency and high quality

The input circuit of the main circuit adopts three-phase three-wire connection, no phase sequence requirement.

SCR is a high current component, so please be sure to tighten the (R, S, T) and (U, V, W) terminals, otherwise it will heat up the terminals and then burn out the SCR.

SCR has a built-in fast fuse for overcurrent and short-circuit protection. If the fuse is blown due to overcurrent, be sure to replace it with a fuse of the same specification. Please do not increase Amps of the fuse arbitrarily!

If the load adopts Y-connection, the neutral point cannot be connected to the neutral line, otherwise the SCR will lose control.

When the heat sink temperature exceeds 75 °C, the over-temperature protection will be automatically turned on and stop the module from working. At this time, only the power status LED is lit.
