TB Series Open Core & Coil Industrial Control Transformers |
• | Acme′s TB Series Industrial Control Transformers are especially designed to accommodate the momentary current inrush caused when electromagnetic components are energized... without sacrificing secondary voltage stability beyond practical limits. |
|
• | Acme′s TB Series transformers are dry-type, step-down transformers with the secondary control circuit isolated from the primary line circuit to assure maximum safety. |
|
• | Voltage regulation of Acme′s TB Series transformers exceeds standards recommended by the National Electrical Manufacturers Association. |
|
• | Secondary circuit voltage drop between no-load and momentary overload remains exceptionally low. |
|
• | This excellent secondary circuit voltage regulation assures reliable operation of electromagnetic components and may permit the use of a smaller and less expensive industrial control transformer. |
