Standex HT01CN231A Industrial Control Transformer

HT01CN231A is a 60 Hz industrial control transformer designed for Carrier HVAC equipment. It accepts 208/230/460 VAC on the primary and provides a 21 VAC secondary rated at 15 VA, enabling a low-voltage power source for relays, sensors, and control boards within Carrier control panels and packaged units. With an input range of 208, 230, or 460 VAC and a 21 V secondary, this transformer supports multiple line-voltage configurations while delivering a modest control-load capacity. The 15 VA secondary rating indicates it can drive several small-control loads without overheating, supporting reliable operation of sequencing logic and safety interlocks in HVAC systems that rely on low-voltage control power.
