Details of Solid State Relay Single Phase Input AC Output VAC (Solid State Relay Single Phase Input AC Output VAC)

SG1-AA015-A1 Single phases Input 80-280VAC Output 24-280VAC Current 15A Zero C Solid State Relay Single Phase (Input AC, Output AC) – Working Principle and Features The working principle of a Solid State Relay with an AC input and AC output is to control the switching of AC loads using an alternating current control 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 cases of high current loads.
• 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 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).
