TB81201 - 

Acme's TA and TB series are dry-type step-down transformers with an open core and coil design. These units are designed specifically for industrial control applications where the energizing of electromagnetic components creates high in-rush current that must be accommodated without sacrificing the voltage stability in the secondary circuit. The TA series is available up to 5000 VA. The TB series products are offered with ratings from 50 VA to 1000 VA; all units are 50/60 Hz rated.
