Details of SG1-AA125-A2 Single Phase Input 80-280VAC Output 48-480VAC Current 125A Zero

SG1-AA125-A2 Single phase input 80-280VAC output 48-480VAC current 125A zero solid state relay single phase (Input AC, Output AC) – Operation and features Solid State Relay with Input as AC and Output as AC 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 to operate the power section.
• Output AC (e.g., 24–480VAC): Controls the delivery of current to loads such as heaters, motors, and lamps.

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.
• Loading Capacity: Typically supports from 2A to 100A (depending on the model and Heat Sink).
• Cooling: Must use a Heat Sink or fan in case of high current loads.
• Isolation: Prevents signal interference and increases installation safety, usually DIN Rail or mounting plate type.
• Response Time: Approximately 1–2 milliseconds.

Advantages

• No moving parts – No wear and tear.
• Operates quietly.
• Durable against vibration and dust.
• Able to control loads accurately and quickly.
• Long service life.

Cautions

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