How the Hoymk AMR-40DD Works
The Hoymk AMR-40dd Max Power operates through solid-state switching mechanisms, eliminating the need for mechanical contacts.
Control Signal Activation
When a DC control voltage between 3V and 32V is applied to the input terminals, the internal optocoupler or LED driver is energized. This triggers the switching component, typically a MOSFET or thyristor, to turn ON the output circuit.
High-Speed Switching
Unlike traditional relays that require physical movement of contacts, the Hoymk AMR-40DD enables instantaneous switching. This makes it ideal for applications requiring fast, precise, and frequent switching without wear and tear.
Safe and Silent Operation
Since it does not rely on mechanical contacts, the Hoymk AMR-40DD operates silently with minimal energy loss. Additionally, the absence of arcing ensures safe switching in volatile environments such as battery management systems and industrial control circuits.
