Feature: 1. [DC Control AC] Through 3‑32VDC console voltage, control 24‑480VAC voltage circuit, avoid introducing a large number of high voltage circuits to the console. 2. [Fast Switching Speed] Relays have a short switching time of ≤10ms, no spark, no noise, and can be used in high frequency applications. 3. [Durable Housing] The relay is made of high pressure phenolic plastic as the housing, which has good anti vibration and long service life. 4. [Easy Installation] Relays have a simple design and wiring for easier use, small size and light weight for easier installation. 5. [Widely Used] Relays are suitable for computer peripheral interface equipment, electric furnace heating and thermostat equipment, CNC machinery, industrial automation devices. Signal lights, traffic lights. Specification: Item Type: 3 Phase Solid State Relay Material: High pressure phenolic plastic, brass Control Voltage: 3-32VDC Load Voltage: 24-480VAC Control Current: ≥10MA Dielectric withstand Voltage: 2000VAC Through State Voltage Drop: ≤1.5V Leakage Current: ≤5MA Conductivity Time: ≤10MS Ambient Temperature: -30℃-70℃ Color: White. Package List: 1 x 3 Phase Solid State Relay1 x Dustproof Cover Note: Solid state relay product selection considerations:1. When choosing the product, the nature of the load should be different, leaving a different margin in the current grade. (Resistive load, can be selected by 2‑3 times the load current. When inductive or capacitive load, it can be selected by 3‑5 times the load current, and the motor is selected by 5 times or more.)2. According to the relationship between load current and ambient temperature, when the ambient temperature is higher or the heat dissipation condition is not good. Current capacity should be increased. In order to prevent the load from short circuit when using, it is required to connect the fast circuit breaker switch or fast fuse in series with this product in the load circuit.3. In case of inductive load, a voltage sensitive resistor should be connected in parallel with the output to prevent damage to the thyristor in case of overvoltage. The optional varistor (MOV) is 430‑470V for 240V and 680‑750V for 440V.4. When installing, the contact surface between the heat sink and the product must be flat and clean, and evenly coated with a layer of heat conductive silicone grease on its surface, and finally the set of flat washers, spring washers and screws are tightened symmetrically to fix.5. When the solid state relay for the first time after the work stop, it should be while it still has residual temperature and then tighten the fixing screws, so that the solid state relay base plate and heat sink surface can be in close contact, to achieve the ideal heat dissipation effect.6. The nominal current of different models of solid state relays is the nominal current at an ambient temperature of 40℃, so the heat dissipation should be sufficient! 7. Note that the load side do not use a multimeter to determine the good or bad of the product!
