描述
规格
The SSR-40DA series is an industrial-grade single-phase solid-state relay. It adopts a mechanical-free contact structure and uses semiconductor devices (such as thyristors) as the core switching elements to replace the contact switching of traditional electromagnetic relays. It features high reliability, long lifespan, no noise, and fast response, and is widely applicable in the switch control scenarios of AC/DC loads. It can precisely meet the power demand of fields such as automation equipment, heating systems, and motor control.

产品描述
Step 1：Select the control method
(1)AA:AC control AC(2)DA:DC control AC(3)VA:Solid-state pressure regulatorStep 2：Calculate the magnitude of the currentEquipment current ÷ coefficient = selected currentSelected current × coefficient = equipment currentStep 3：Select the appropriate radiator
The solid-state relay generates a considerable amount of heat. When the input current of the load exceeds 10A, a heat sink must be used in conjunction with it. Apply thermal conductive silicone grease between the base plate of the solid-state relay and the heat sink. For currents above 60A, add a fan for forced cooling.
