Allen-Bradley 12664790 Transformer Control Panel

The Allen-Bradley 12664790 Transformer Control Panel is a single‑phase, industrial‑grade control transformer that provides voltage step‑up and step‑down with electrical isolation for control circuits in industrial and commercial power systems. It features natural air cooling, industrial insulation, and panel or chassis mounting, with application‑dependent primary and secondary voltages and 50/60 Hz operation. Commonly installed in control panels, industrial machinery, power supplies, and HVAC systems, it helps keep auxiliary equipment and control circuits stable and isolated. The part is designed for equipment repairs, panel retrofits, and power distribution upgrades where reliable voltage transformation is required.
