Tekmar Controls 009K Transformer
For veteran technicians looking for a reliable, code-compliant power solution, the Tekmar Controls 009K Transformer kit is the standard for hydronic heating and HVACR control systems. This heavy-duty 40VA control transformer steps down 120V AC primary power to a stable 24V AC secondary output, providing ample amperage for multiple zone valves, stats, or advanced tekmarNet communication modules. Unlike bare-bones alternatives, the 009K includes a dedicated 4"x4" electrical J-box and a replaceable 2.0A in-line slow-blow fuse to ensure circuit protection against low-voltage overloads during startup or staging. The color-coded lead wires simplify in-phase wiring, which is critical when paralleling multiple 24Vac transformers for high-load systems. Engineered for durability, this Class 2 transformer is CSA and UL 5085 approved, making it an essential component for any professional low voltage control wiring project requiring a secure, junction-box mounted step-down transformer that withstands demanding boiler room environments.
Key Benefits
- Integrated Circuit Protection: Features a factory-installed 250V, 2.0A slow-blow in-line fuse to prevent transformer burnout from secondary shorts.
- Installation Ready: Packaged with a standard 4x4 inch metal junction box for secure mounting and immediate code compliance.
- Phasing Simplified: Color-coded wiring allows for easy identification, ensuring multiple units can be wired in phase to increase total VA capacity.
- Robust Power Delivery: Provides 1.67A at 24V AC, sufficient for powering complex control logic and multiple actuators without voltage drop.
- Industrial Standards: Fully compliant with CSA C22.2 No. 66 and UL 5085 for indoor commercial and residential applications.
Common Questions
What is the maximum load this transformer can handle?
The 009K delivers a total of 40VA. If your sum of zone valves and controls exceeds 1.67 Amps, you should parallel multiple units in phase or upgrade to a higher VA rated kit.
Can this transformer be used for powering hydronic zone valves?
Yes, it is specifically designed to provide the 24V AC "R" and "C" power required for hydronic thermostats, zone valve actuators, and mixing controls.
What happens if the secondary circuit shorts out?
The included 2.0A slow-blow fuse is designed to sacrifice itself to protect the transformer's copper windings. If power is lost, check the integrity of the in-line fuse before replacing the entire 009K unit.
