Solid State Relays

Solid State Relays (SSRs) are switching devices used for controlling electrical loads. They use semiconductor controlled switches, such as thyristors, TRIACs, MOSFETs, and IGBTs, instead of mechanical relay contacts to open and close electrical circuits. SSRs are silent, fast responding, and can be used for controlling loads up to a few hundred watts with a voltage ranging from 0-960 VAC.The PVDZ172NS is a type of SSR, specifically a zero-crossing SSR. It uses a zero-crossing detector that senses the zero-cross reference point of the input alternating current (AC) waveform. When the zero-crossing point is reached, the detector triggers the SRR switch, either closing or opening the circuit depending on the control signal from the application.The PVDZ172NS is rated for a load voltage of 24-940 VAC and a current of 12A. It is designed for controlling both resistive and inductive loads, and has an integrated snubber circuit to protect it from AC transients. It also has LED indicators which indicate when the relay is open or closed.The PVDZ172NS can be used in a variety of applications including HVAC, lighting control, motor control, and hot water systems. When used in these applications, the PVDZ172NS provides smooth and silent switching, greater protection from overloads, and increased efficiency.In addition to controlling AC loads, the PVDZ172NS can also be used for switching DC loads. This is achieved by connecting the DC load in series with a DC-to-AC inverter. The inverter is driven with a DC control signal, and the SSR acts as a switch between the inverter and the DC load. This configuration can be used for powering DC devices such as LED drivers, air conditioners, and heat pumps.In summary, the PVDZ172NS is a type of solid state relay which is designed to switch AC and DC loads. It is rated for a voltage of 24-940 VAC and a current of 12A, and is ideal for controlling both resistive and inductive loads. It is used in a variety of applications ranging from HVAC and lighting control to motor control and hot water systems.
