Why Choose the ABB TMI320115230P Control and Isolating Transformer?
The ABB TMI320115230P, type TM-I 320/115-230 P, is a 320 VA single-phase control and isolating transformer designed to provide voltage transformation and electrical separation for industrial control and auxiliary circuits. The primary and secondary windings are electrically separated by double or reinforced insulation, helping protect the secondary circuit against hazards associated with insulation faults.
Part of ABB's TM-I range, this transformer uses a 230–400 V AC primary circuit with separate ±15 V adjustment terminals for precise adaptation to the incoming voltage. The secondary provides selectable 115 or 230 V AC, with full rated power available at the outputs.
With a rated apparent power of 320 VA, the TM-I 320/115-230 P is designed for continuous operation and mounting on a suitable installation plate. Its robust open-frame construction and compliance with IEC/EN 61558-2-2 and IEC/EN 61558-2-4 make it suitable for professional machinery, automation and electrical-panel applications.

Reliable Electrical Isolation for Control and Auxiliary Circuits
The ABB TM-I 320/115-230 P electrically separates its primary and secondary windings using double or reinforced insulation. This arrangement provides galvanic isolation for the secondary circuit while simultaneously converting the incoming industrial supply to the required 115 or 230 V AC control voltage.
Its 320 VA capacity makes it suitable for supplying appropriately sized contactors, relays, signalling equipment and other control loads. The ±15 V primary adjustment terminals provide additional flexibility when adapting the transformer to actual supply conditions, while continuous-duty construction supports sustained use in industrial electrical systems.
Typical Applications
- Industrial machinery control circuits.
- Automation and process-control panels.
- Electrical switchboards and distribution equipment.
- Isolated auxiliary power supplies.
- Contactor, relay and signalling circuits.
- OEM machinery and production equipment.
- Control systems requiring 115 or 230 V AC secondary power.
