6 FAQs about [Ac power solid state relays]
What voltage is a solid state relay based on?
Solid state relays can be designed to operate either based on AC or DC input currents, depending on the specific model and applications. Common voltages for DC input include 5V, 12V and 24V DC solid state relays, while widely available examples of AC solid state relays are often based around 120V or 240V AC input.
What is a DC to AC Solid State Relay (SSR)?
A Solid State Relay (SSR) uses an Optocoupler to isolate the control circuit from the controlled circuit, unlike an Electromagnetic Relay (EMR) with a coil and mechanical switch. A DC to AC SSR relay operates as shown in the general schematic below:
How does a solid state relay function?
A solid state relay (SSR) works by using an SCR, TRIAC, or switching transistor output to switch both AC or DC currents, instead of the usual mechanical normally-open (NO) contacts.
What are the typical input voltages for AC solid state relays?
Manufacturers produce and sell AC input solid state relays with input voltages typically ranging from 90 to 280 volts AC. As with the input, the output switching capabilities of a solid state relay can be either an AC or DC voltage.
What type of switching device is used in a solid state relay?
In a solid state relay, the output circuit is configured to perform a normally-open, single-pole, single-throw (SPST-NO) operation. For most DC SSR’s, the solid state switching device commonly used are power transistors, Darlington’s and MOSFETs.
What does the relay operate on?
This relay operates on DC input to switch an AC Load Circuit. There are different types of SSR (Solid State) relays. They are either classified on their Input/output form or their switching property. Following are some of the common types of SSR relay classified based on its input and output circuit (AC/DC).
