Description
Product Description:※ ※ ※ Product Name: Solid State Relay Single phase
※ ※ ※ Product model: 50DA optional
※ ※ ※ Current:DC controlled AC

※ ※ ※ Product features: strong anti-interference, convenient installation, silent, no contact, no spark, etc.
※ ※ ※ Calculate the current size:
※ ※ ※
※ ※ ※
※ ※ ※
Equipment current ÷ factor = selection current
Selection 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: 15A×2=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: 15A×6=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.
