Q117UM-2

Product Description:

Danaher manufactures the Q117UM-2. The 240V input voltage of the Q117UM-2 POWERSTAT Transformer is what makes the laminated ferromagnetic core tick. In this case, voltage is the electrical potential energy to causes the magnetic flux to circulate in the closed magnetic path of the core. An electromotive force (EMF) is induced across the secondary winding by the time-varying magnetic field created by the primary winding when it is powered with the specified voltage. Any deviation from this nominal voltage will alter the mutual induction process and compromise voltage regulation by slowing down the rate of magnetic field change. The output voltage responds non-linearly, which can cause harmonic distortion, thermal instability, or core saturation, especially when there is a dynamic load. So, maintaining accuracy requires a strictly controlled 240V supply, especially in applications that require precise voltage conversions and minimal harmonic noise.

The magnetic permeability of the core and the inductive reactance of the primary and secondary windings are both affected by the 60Hz input frequency. Core losses in AC transformers (hysteresis and eddy current losses) increase with frequency and magnetic flux density. A deviation from 60Hz will alter the input waveform’s sinusoidal quality, change the winding’s impedance, and maybe cause phase shift or core overexcitation. These disruptions can cause ineffective magnetic coupling and higher copper losses. So the transformer’s thermal envelope can be exceeded, especially when the load profiles are capacitive or inductive. The exact electromagnetic coupling required for reliable power transmission and transformer efficiency across a range of loads is achieved by running the transformer at its nominal frequency, which preserves the reactance and phase relationships.

The most unique feature of the Q117UM-2 is its manually adjustable variac-style output, which allows for smooth voltage adjustment from 0 to 240V. A wiper mechanism that travels along a toroidal winding does this by essentially changing the winding ratio between the primary and secondary coils. No PWM or mechanical switching is required for real-time output voltage adjustment according to Faraday’s law of electromagnetic induction. The transformer can handle up to 10A and 2.4 KVA continuous current load; its electrical and thermal design is optimized for resistive or current-stabilized systems. It can handle up to 13A and 3.1 KVA continuous impedance load, it’s a good impedance match, and has low reactive losses. Terminal labeling for clockwise and counterclockwise adjustment ensures accurate user-controlled output tuning, and typical industrial wiring procedures are followed with the "#2 1-Phase Series" connection type, which is designed for single-phase systems. The Q117UM-2 is part of voltage-sensitive automation applications such as lab-grade power supply sets, high-precision temperature control systems and analog motor drives because of its adjustability and power stability.
