Feature:1. INTELLIGENT CHIP: The relay operates stably and has strong overcurrent. The isolation between the control terminal and the load terminal is realized by an isolator.2. RED COPPER BOTTOM PLATE: The relay adopts red copper base plate, the surface is flat, the heat dissipation is fast, and it has the function of overheating protection.3. SAFE USAGE: There is no need for internal mechanical contact when the relay is running, no sparks are generated, low noise, and it is safer and more secure to use.4. ABS MATERIAL: The relay is made of ABS material specially used for industrial electric heating, which is environmentally friendly and safe.5. WIDE APPLICATION: Relays can be widely used in aerospace, ships, household appliances, machine tools, communications, automobiles, mining, automation control and other fields.Specification:Item Type: Industrial Solid State RelayMaterial: ABS, red copperModel: H3400ALoad Current: 400AOn Off Time: 10msInput Voltage: 3-32V DCOutput Voltage: 24-480V ACAmbient Temperature: -30-70Off State Leakage Current: 5mAPlacement Method: Bolt fixingWork Indication: LEDControl Mode: DC to AC.Package List:1 x Industrial Solid State Relay2 x Power CableNote:How to calculate current:Equipment power voltage = currentCurrent coefficient = select solid state currentThe factor depends on the load type of the equipment you are bringingResistive load: 60%Inductive load: 30%For example: a motor rated at 1500W, the motor is an inductive load, then the formula: 1500W220V=6.8; 6.80.3=22A, we need to choose to buy a 25A solid state relay.
