Note: the Solid State Relay Generates a Lot of Heat. When the Load Current Is Greater than 10A, It Needs to Be Used with a Radiator. Between the Bottom Plate of the Solid State Relay and the Radiator Should Be Coated with Thermal Grease. When the Load Current Is Greater than 60A, a Fan Needs to Be Used to Cooling and Heat Dissipation.

Features

2. the Screws Are Made of High-toughness Anti-rust Material, Which Is Not Easy to Break. the Sliding Wire Column Is Made of Red Copper Material.
3. the Shell Is Made of High-quality High-temperature Flame-retardant Materials, Which Are Bright and Durable.
4. the High-purity Copper Bottom Plate Has Obvious Heat Dissipation Effect, and It Is Not Easy to Generate Heat After Long-term Use.
5. There Are Many Varieties, Complete Specifications, Convenient and Flexible Installation, Convenient Maintenance, and Better Cost Performance.

Application
The Relay Adopts the Internal Working Method and Does Not Need Internal Contact to Work. Built-in Smart Chip, Using Isolation Devices to Achieve Isolation Between the Control End and the Load End. Silent and Non-sparking.
It Can Be Widely Used in Aerospace, Shipbuilding, Household Appliances, Machine Tools, Communications, Automobile, Mining, Automation and Control.

Tips on How to Choose a Solid State Relay Model:
⇒Equipment Current ÷ Coefficient = Current of the Selected Model ( Coefficient: Resistive Load Is 2, Inductive Load Is 6 )
⇒Resistive Load: Electric Heating, Incandescent Lamp, Resistance, Etc.
⇒Inductive Loads: Motors, Transformers, Capacitors, Solenoid Valves, Air Conditioners, Lighting with Inductance, Etc.
⇒Example a: a Heater with a Rated Current of 15a, and the Heater Is a Resistive Load, Then According to the Formula: 15A X 2 = 30A, You Should Choose to Buy a 40a Solid State Relay.
⇒Example B: a Motor with a Rated Current of 15a, and the Motor Is an Inductive Load, Then According to the Formula: 15A X 6 = 90A, You Should Choose to Buy a 100a Solid State Relay.
