Q116U-3

Product Description:

Danaher manufactures the Q116U-3. Danaher makes the Q116U-3. The Danaher Q116U-3 POWERSTAT Transformer is a high-tech voltage control device that can handle 240 volts input with 50 Hz and 60 Hz frequency tolerance. The dual frequency capability is due to the optimized magnetic core design to minimize hysteresis and eddy current losses across global power standards. The 3-phase Wye configuration provides stable voltage to the load and allows for phase balancing and single-phase equipment. The open core design requires environmental protection during deployment, especially in areas with contaminants or mechanical risks. Even at no load at 60 Hz, it has 25.5 watts of core loss due to continuous magnetic excitation. These losses affect thermal management and energy budgeting in continuous run applications.

The adjustable output voltage from 0- 240V to 0- 280V is achieved through an autotransformer design with a common winding and a movable tap. This eliminates the need for separate primary and secondary windings and results in higher efficiency and less material usage. The variable tap point changes the turns ratio and allows for fine control of the secondary voltage output. This is critical in industrial applications such as motor drive regulation, lighting dimming systems, and heat process control, where power is dynamic and precise voltage is required. The system can supply up to 9 amps constant current load, 3.8 to 4.4 kVA apparent power, and 12 amps constant impedance load, 5.0 kVA. This shows its capability to handle continuous operation.

Mechanically, the Q116U-3 has a manual or motorized voltage adjustment system that requires 50-75 in-oz of torque. This torque range gives design constraints for automated control interfaces or ergonomic manual adjustments. With a per-coil D-C resistance of 0.49 ohms, the transformer has predictable I²R losses that affect efficiency and thermal loading, especially when used for long periods at higher currents. The terminal designations indicate the jumper, input and output connections to guide the wiring during installation to maintain phase integrity and avoid operational faults. Every specification from electrical input to physical layout is a high degree of integration of thermal, magnetic, and mechanical systems. Together, they define a transformer designed for adaptive high-performance deployment in advanced industrial automation systems where voltage regulation precision and electrical ruggedness are non-negotiable.
