Questions about this item

Will the SE-350's 24 V 14.6 A output run my older S-210 or S-320 equipment without changes?

Yes, the SE-350 is designed as an upgraded replacement for both the S-210 and S-320 series and delivers the same 24 V output.

How can I confirm the built-in fan is operating correctly after installation?

The fan runs only when internal temperature requires it; you will hear it spin up under load and stop when the unit cools.

Does the box include mounting brackets and AC cable or must I source them separately?

The unit ships as an open-frame AT power supply; mounting hardware and mains lead are not included and must be purchased separately.
