Karismar AS 250504 Generator Power Supply & Control Module | Ver. 01/001/03/A2

Karismar AS 250504 Industrial Generator Power Management Board

Enhance signal reliability and distribution stability inside your control cabinetry with the Karismar AS 250504 Power Module. Engineered to rigorous Scandinavian maritime and power plant standards, this multi-layered interface board handles incoming line filtration, voltage step-down regulation, and local communication routing on a single integrated footprint.

The card features a heavy-duty Schaffner FN 402 AC filter block coupled with large copper toroidal chokes and smooth electrolytic capacitors to thoroughly suppress electrical line noise and high-frequency harmonics before they reach sensitive controller circuits. For logic networks, the card integrates a Maxim MAX232 driver array alongside dual RJ45 interface jacks, allowing fast data loop-through and remote diagnostic hookups.
