DescriptionSolid state relays are semiconductor devices and generally generate a lot of heat during operation. When the load current is higher than 10A, a radiator must be used, and thermally conductive silicone grease must be applied between the bottom plate of the solid state relay and the radiator (above 60A) (Forced cooling by fan).Features- Color: Assorted color.- Material: Plastic, metal.- Size: 5.70X4.50X3.00cm/2.24X1.77X1.18 inch.- Output current: 40A.- Control voltage: 3-32VDC.- On-state buck: ≤1.6V.- Control current: 5-20mA.- Load voltage: 20-480VAC.- On-off time: ≤10mS.- Good optocoupler operation is more stable, excellent power cycle and temperature characteristics.- Built-in smart chip, higher control frequency and higher precision.- Can withstand frequent frequency control and precise control of current.- Thicken electroplated aluminum plate, welding of thyristor devices, faster heat dissipation.- Semiconductor original output, no mechanical action, no noise, no sparks.
