10 Amp, 25 Amp, 40 Amp, 60 Amp, 80 Amp, 100 Amp
Input DC 3-32V to Output DC 5-200V Solid State Relays Module Single Phase SSR DD-Series
High-quality materials, Industrial Grade, environmentally friendly, safe, reliable, and durable. strong anti-interference, small size, light weight, many varieties and complete specifications, convenient and flexible installation, convenient maintenance and better cost performance.
The dedicated solid-state relay has the functions of short-circuit protection, overload protection and overheat protection, and with the combination logic solidification packaging can realize the intelligent module required by the user, which can be directly used in the control system.
There are no mechanical parts inside the solid state relay, and the contact function is completed by a solid device. Because there are no moving parts, it can work in a high impact and vibration environment to achieve contactless, non-sparking connection and disconnection is controlled Circuit.
The metal heat dissipation base plate is used at the bottom to increase the stability and sensitivity of the product, achieve timely heat dissipation, and ensure the sustainable operation of the product.
Special photoelectric coupler is used for isolation, fast switching speed, high working frequency, long service life, low power consumption, improved work efficiency, flame-retardant plastic shell, dustproof and high temperature resistance.
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.
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.
