SG1-MA25-A2 Single phases Input 4-20mA Output 48-480VAC Current 25A Phase Cont Solid State Relay – Phase Control Type for Single Phase that supports Analog Input such as 4-20mA or 0-10VDC and has an Output of AC Voltage range 24-280VAC is a non-contact Switch electrical control device suitable for loads requiring precise power control, such as heaters, lamps, or small motors

Working Principle

This type of Solid State Relay works based on the principle of Phase Angle Control which means controlling the duration of AC sine wave opening in each cycle of electricity: Analog Input (4-20mA or 0-10VDC) is converted into a control signal within SSR. The internal system delays (Delay) the opening of the AC signal in each half-cycle (Half Cycle) of power. The more input, the relay opens earlier in the sine wave, sending more energy to the load. As a result, the load (such as heater) receives more or less energy according to the input.

Features

• Detailed control with analog signals such as 4-20mA or 0-10VDC, no moving parts, thus durable, silent operation, supports AC voltage from 24VAC to 280VAC
• Phase Angle Control for continuous power control without flickering
• Thermal protection system (in some models) and Snubber circuit to reduce noise, high-speed switching (on/off within a few milliseconds)

Applications 

• Control heaters especially temperature-sensitive heaters, industrial plastic machinery requiring precise temperature control
• Industrial ovens
• Lighting control system (Dimmer) for halogen lamps or some reactive loads
• Automated systems using PLC or Controller outputting analog signals
