Single Phase Solid State Relay Ssr- 10/25/40/60/80/100dd Semiconductor Relay Module

Descriptions Solid State Relays are high quality relays and are available in a variety of models.Product Description: Product Name: Solid State Relay Product model: 10/25/40/60/80/100DD optional Current: DC controlled DC Control current: 3-35MA Control voltage: 3-32VDC Load voltage: 5-200VDC On-state step-down: 1.6V On-off time: 10MS Ambient temperature: -30C~+70C Product features: strong anti-interference, convenient installation, silent, no contact, no spark, etc. Calculate the current size: Equipment current factor = selection currentSelection current coefficient = equipment current (coefficient: resistive load is 2 times, inductive load is 6 times.)Resistive load: electric heating, incandescent lamp, resistance... etc.Inductive loads: motors, transformers, capacitors, solenoid valves, air conditioners, lighting with inductance... etc.Example 1: A heater with a rated current of 15A, and the heater is a resistive load, then the formula: 15A2=30A, you must choose to buy a 40A solid state relay. Example 2: A motor with a rated current of 15A, and the motor is an inductive load, then the formula: 15A6=90A, you must choose to buy a 100A solid state relay. Reminder: 1. 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. Apply thermal grease between the solid-state relay base plate and the radiator, and add a fan for forced cooling above 60A.2. In the closed state, there is an off-state leakage current 5mA, which is not applicable to special scenarios. Please purchase with caution.
