Frequently Asked Questions

Which equipment types typically use TMR 3-4811?

TMR 3-4811 is suitable for industrial controllers, instrumentation, and communication modules needing 3 W of regulated isolated DC/DC power.

How much isolation is available between input and output?

The converter description specifies 1600 VDC I/O isolation, helping separate field-side electronics from logic rails in compact industrial systems.

What mechanical format should be matched when approving an alternate?

Approve alternates against the encapsulated SIP-8 format and 7-pin footprint, because the PCB hole pattern must match the installed converter.
