STEP 1: Choose a correct control Model
DA: DC control AC Input: 3-32VDC Load:24-480VAC
AA: AC control AC Input: 70-280VAC Load:24-480VAC
DD: DC control DC Input: 3-32VDC Load:5-220VDC
STEP 2: Choose a correct type for current
For Resistive load: Current of SSR =3 x working current of load
Resistive load such as Resistance furnace, Incandescent lamp, Oven, Heating rod, Electric water heater.
For Inductive load: Current of SSR =6 x working current of load
Inductive load such as Motor,Fan,Transformer,Pump,Air conditioner and other loads with inductives.
For Capacitive load: Current of SSR =10 x working current of load
Capacitive load such as Compensating capactitors,Batteries and other loads with capacitors
STEP 3: Choose a suitable heat sink.
The temperature of heatsink at use must below 80℃ .Apply heat-conductive silicon grease between SSR and heatsink.
Attentions:
1. SSR cannot be tested without load,and must be added load of more than 50W to test
