Product Description:
Danaher manufactures the Q216U-2. The DC resistance of the Danaher Q216U-2 POWERSTAT transformer is a great example of precision electrical engineering. The material, cross section, and length of the conductor in the windings all affect the resistance of each coil, which is 10.8 Ohms. This is not just a passive characteristic; it plays a big role in how the transformer behaves in steady state and transient DC-influenced operation. In DC or low-frequency transient circuits, it controls the amount of resistive voltage drop, thermal dissipation, and reaction time. For thermal management and power loss modeling, a well-specified DC resistance is important, especially in systems with fluctuating loads or extended energization without load transfer.
When turned on at 60Hz, the Q216U-2 shows no load losses of 13.0 Watts, which is the core loss profile of the transformer when there is no secondary current flowing. These losses are mainly caused by magnetization processes in the core, such as eddy currents induced by the alternating magnetic flux and hysteresis, which is related to the realignment of the magnetic domain. The permeability and electrical conductivity of the core material and the geometric optimization of the core laminations all affect the size of these losses. Reducing energy conversion efficiency, thermal stress, and increasing life all depend on minimizing these parasitic losses, especially in applications where the transformer may be left powered for extended periods of time with intermittent load engagement.
Through a 4.3 to 5.4 kpcm or 60 to 75 oz-in torque mechanism, the Q216U-2 mechanically regulates the voltage. For manual or automated output voltage adjustment, this torque standard provides constant rotational resistance. This rotating control varies the transformer output, which can be 0 to 560V depending on the input voltage and direction. It can operate at higher frequencies up to 1500Hz, is compatible with 50/60Hz grids, and can handle 240V and 480V input systems. Its electrical flexibility includes 3-phase open delta and 1-phase series configurations and can be tuned for various load profiles such as constant current and constant impedance. Its robustness in dynamic industrial automation applications where accuracy, adaptability and reliability are critical.
