Titus 101003-01 is an OEM step-down control transformer that converts 480 VAC primary power to a safe and stable 24 VAC secondary output at 50 VA for Titus HVAC equipment. Designed for use with Titus electric coil and control circuits, it reliably feeds thermostats, actuators, relays, and safety controls wherever a 24-volt control signal is required in commercial or industrial air-handling and heating systems. The 50 VA rating provides ample capacity for typical low-voltage loads, helping prevent nuisance trips, low-voltage lockouts, and intermittent control issues that can take critical HVAC zones offline. As a direct Titus replacement part, this transformer is ideal for service repairs, upgrades, or preventative maintenance on units that specify 101003-01 or a 480V to 24V 50VA control transformer, reducing troubleshooting time and ensuring proper fit and operation. By restoring clean, consistent low-voltage power to your control circuit, this transformer helps protect connected components, extend equipment life, and keep comfort and process temperatures stable for gas or electric HVAC applications.
