ULTRA LOW EMISSION SOLID STATE RELAY

According to one embodiment, a solid state relay with ultra low emissions is disclosed. The solid state relay includes one or more inputs for receiving a control signal, an input circuit for processing the received control signal. An output circuit responsive to the control signal to close the solid state relay so that power may be delivered from a power source to an electrical load. The input circuit can include zero-crossing functionality configured such that the solid state relay does not turn on until an AC source signal crosses from a negative value to a positive value or from a positive value to a negative value. The zero crossing functionality may comprise opto-couplers with zero crossing functionality. The input circuit may further comprise a low emission driver portion that is to reduce emissions during the portion after the initial start up.
