Industrial ST-6214 9106 NN3 Control Transformer

Description:

The ST-6214 / 9106 (NN3) Transformer is a 100 VA control transformer with 24V primary and 24V secondary windings used in industrial control and power distribution systems to provide isolated low-voltage power. Commonly installed in control panels, machine tools, HVAC equipment, and manufacturing machinery where stable auxiliary power and electrical isolation are required. Maintenance technicians, OEMs, and system integrators use this transformer for equipment repairs, replacement of failed control transformers, and retrofits of industrial electrical systems. Control transformers with 24V primary/secondary ratings and 100 VA capacity are commonly used in industrial automation and safety circuits.

Applications:

The ST-6214 / 9106 transformer is designed to provide isolated control power in industrial and commercial electrical systems. It is commonly used in control cabinets, PLC panels, machine tools, packaging equipment, HVAC systems, and OEM machinery where a reliable 24 VAC power source is required for relays, contactors, indicators, and control circuits. The 100 VA rating provides sufficient capacity for multiple control devices while maintaining electrical isolation between circuits.
