What is a SSR?
Solid State Relays (SSRs): SSRs
are semiconductor devices that canbe used instead of mechanicalrelays to switch electricity to a loadin several applications.
They are purely electronic devices,
normally composed of a low current
control side and a high current loadside (switching side). SSRs featureelectrical isolation in thousands ofvolts between the control and theload side.
This is achieved through opticalisolation using an optoelectronic
device, such as a photo coupler.

Solid State Relays
Why use? Advantages – Limitations of SSR
Advantages:- Long life and reliability- High switching frequency- No contact arcing and bounce- Maximum switching capacity- Vibration and shock resistance- No electromechanical noise- Electromagnetic noise resistance- Phase angle control mode
- High switching speed- Logic compatibility- Low input current

No moving parts, no mechanical were and tear
Detect high switching signals
Do not generate sparks or arcs
Designed for AC an DC
Withstand shock and vibration compared with EMR
No moving parts
Reduced electro magnetic noise (EMI)Fine resolution of power for dimming - soft starting
Very fast switching capability - µs–ns
Can be switched on and off by a digital system
Switching of large loads via a low level logic signal

Limitations:- Higher cost
- Thermal dissipation- Off-state leakage current

Compared with EMR
My require heat sink
When switch is open or OFF

In a technical context, the SSR is almost always preferred to the EMR.

Select an SSR?

Please also refer to our web page: Precautions on Use of SSR

Identify the load voltage
Determine whether you need to switch AC or DC voltage,and please select the SSR of the load voltage range according tothe load voltage connected to the output side of SSR.

Load current
Choose an SSR with of rated current is greater than or equal to the current value flowing to the output side of the SSR.※SSR
generates heat due to characteristics (voltage drop) of the semiconductor. Therefore, the current value that can flow
depending on the ambient temperature of the SSR changes. Attention must be paid to the load current characteristics of eachproduct.

Surge current
At the moment the SSR turns ON and the load operates, a much larger current than the steady state called surge current mayflow. Especially inductive loads such as motors and pumps, and capacitive loads such as incandescent lamps generate surge
current. Do not exceed the surge current rating of each SSR.

Zero cross function
when controlling inductive loads such as solenoid valves and motors, the SSR with zero cross function may malfunction due tothe phase shift between the voltage and the current. When controlling the inductive load, zero cross not built in type will berecommended.
