220V AC Solid-state Relay Small Single-phase 40A DC Control AC Module SSR-40DA 10A25A60A100A DC/AC DDAA Relay 24V 220V
Description
Product Description
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.

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