General monostable integrated power-control circuit U2100B used according mode selection relay triac applications. Beyond that, used triac applications two-wire system power switch (the load series switch), where supply voltage control unit gained from phase rest angle (amin-operation). three-wire switch systems, operation modes possible: Zero voltage switch operation triac control Static operation relay control
Mode Selection Supply Voltage
Operation modes selected external voltage sync. input (clamping). Mode selection determines current requirement relay's triac's driver stage hence selection supply voltage.
