AC-AC SSR 120A 3-Phase Solid State Relay, Input AC 70-280V, Output AC 24-480V

Product :Three-Phase Solid State Relay

Model:SSR-3 A4810 A4825 A4840 A4860 A4880 A48100 A48120 A48150 A48200

Current:10A 25A 40A 60A 80A 100A 120A 150A 200A

Controlmode : AC control AC

Controlvoltage :70-280VAC

Load voltage :24-480VAC

Step 1: Choose a correct control Mode
AA- AC Control AC

Step 2: Choose a correct type
Current of Equipment/Ratio = Current of SSR
PS: The Ratio depend on the kind of your loading equipment.
Resistive load :70%, Inductive load:20%,Capacitive load：10%.

Step 3: Choose a suitable heat sink
During the useage of SSR, it will give out a lot of heat, so in order to extend the life of your SSR, please install a heat sink , also if the current is over 60A,the cooling fan also required.

Notice:
The inside of the solid-state relay is a semiconductor. A semiconductor switch is a non-physical contact switch. if use a multimeter diode or resistor to test ,it always show a high-impedance state, (multimeter light red).
According to the conventional detection methods of solid state relays: a load is required to test the switching state. Using an incandescent lamp as a dummy load is an obvious way to test continuity.Zhejiang Lingshine Electric Co., Ltd (Aigoodele), is a high-tech enterprise integrating production, sales and service. Our main products are frequency converter (VFD), soft starter (LSRQ), solid state relay (SSR), solid state voltage regulator (LSCR), high power rectifiers and so on (KP, ZP, MTC, MDS, MDQ, MDC, MDK, ETC). These products have been widely used in energy, petroleum, metallurgy, chemical industry, construction, plastics, textile, water supply, paper making, mining, printing and many other industrial fields. In addition, our products not only perform well in the domestic market, but have also been exported to dozens of countries and regions in Asia, Africa, Europe and other continents, winning wide international recognition.

We look forward to cooperating with every customer, welcome your guidance and suggestions, and work together to create a more brilliant future.
