1. Increasing load capacity of phase cut modulation in the triac manual knob and lighting control system, can be compatible with the systems of Philips, Panasonic, Lutron etc. 2. Cost savings. Compared with increasing the dimmer module, the cost of using this power amplifier is greatly reduced, and convenient for configuration. 3.Supporting leading-edge and trailing-edge phase cut. The output signal is leading-edge phase cut. If the input signal is Trailing edge, pls make sure the consistency of input and output signal of SCR Aplifier. #poweramplifier #euchips
