Packard PF524100 Transformer

When you're out in the field and need a reliable, high-capacity solution for commercial or industrial control panels, the Packard PF524100 multi-tap transformer is a technician’s go-to for versatility. This 100VA foot-mount transformer is engineered to handle a wide range of input voltages, including 120V, 208V, 240V, and 480V, converting them into the standard 24V secondary output required by most modern HVACR controls. Unlike standard 40VA or 50VA units that might trip under heavy inductive loads, the 100VA rating provides the necessary headroom for complex relay boards, motorized dampers, and multiple humidification controls.

Installation is straightforward with color-coded wire leads and a multi-foot mounting base that fits standard footprints for quick retrofitting. This Class II transformer also features a built-in 4-amp circuit breaker with a manual reset button, protecting your secondary side components from shorts or overloads without the need to stock external fuses. Its UL recongnized construction makes it a dependable HVAC 24V replacement transformer for brands like Jard, Mars, and Supco, ensuring you can finish the service call and get the system back online with confidence.

• Universal Compatibility: Supports 120/208/240/480V primary inputs, making it a single-truck stock solution for various job sites.
• Enhanced Power Capacity: The 100VA output ensures stable voltage for systems with high-current draws or multiple accessories.
• Integrated Protection: A 4A circuit breaker prevents site downtime by protecting the windings and downstream low-voltage components.
• Durable Foot Mounting: Secure multi-foot positioning allows for stable installation in existing air handlers or control cabinets.
• Flexible Connectivity: Outfitted with strip-ready wire leads for seamless integration into various wiring harnesses.

Can I use this transformer to replace a 40VA or 75VA unit?
Yes, Packard transformers can replace any unit with an equal or lower VA rating, provided the primary and secondary voltages match your application requirements.

How do I reset the unit if the circuit blocks the 24V output?
Simply locate the white circuit breaker reset button on the top of the unit. Press it firmly to restore the connection once the initial short or overload is cleared.

Is this suitable for both 50Hz and 60Hz operations?
Yes, this Packard 100VA transformer is rated for 50/60Hz, making it compatible with varying power grid standards.
