Details of SG1-AA075-A1 Single Phase Input 80-280VAC Output 24-280VAC Current 75A Zero C

SG1-AA075-A1 Single phase input 80-280VAC output 24-280VAC current 75A Zero C Solid State Relay single-phase (Input AC, Output AC) – Operation and Features The operation of the solid state relay with AC Input and AC Output is used to control the switching of AC loads using an alternating current signal (AC Control Signal)

Main Components

• Input AC (e.g., 90–280VAC): Receives AC control signals.
• Opto-Isolator: Separates the control signal from the power circuit for safety.
• Trigger Circuit: When a control signal is received, it activates the drive circuit of the power section.
• Output AC (e.g., 24–480VAC): Controls the delivery of current to loads such as heaters, motors, and lamps, etc. 

Type Input Voltage Control AC (e.g. 90-280VAC)

• Output Type: Alternating Current Load (AC Load: 24–480VAC or 24–240VAC depending on the model).
• Frequency: 50/60Hz.
• Suitable Loads: Typically supports loads from 2A to 100A (depending on the model and Heat Sink).
• Cooling: Must use a Heat Sink or fan in case of high current load.
• Isolation: Prevents signal interference and enhances installation safety, usually DIN Rail or mounting plate type.
• Response Time: Approximately 1–2 milliseconds.

Advantages

• No moving parts – No wear and tear.
• Silent operation.
• Durable against vibration and dust.
• Precise and fast load control.
• Long service life.

Cautions

• Select the SSR appropriately for the load and operating voltage.
• Avoid leakage current issues that may occur when the SSR is in the "off" state.
• Temperature: Proper cooling must be ensured, otherwise the equipment may get damaged. 
• Control electric heaters in oven systems, lighting systems, industrial machinery systems, automatic temperature control systems, motor control systems (loads not exceeding specified capacity).
