Technical details and manufacturing context for Voltage Regulator/Controller

Definition
The Voltage Regulator/Controller is a component used in high voltage test systems to maintain a stable output voltage despite variations in input voltage or load conditions. It is part of a High Voltage Test Module, where it regulates and controls the voltage supplied to electrical equipment under test, ensuring precise and repeatable test conditions. The device operates by monitoring the output voltage and adjusting internal circuitry—typically through feedback control, switching transistors, or linear regulation—to keep the voltage at a set level. This regulation is critical for accurate testing of insulation, dielectric strength, and other high voltage characteristics.

Key specifications include an input voltage range of 85–265 V AC for global mains compatibility, and a regulated output voltage of 24 V DC with ±1% tolerance. Output current is adjustable from 0 to 10 A, with derating above 50°C. Line and load regulation are both ±0.5%, ensuring stable output under varying conditions. Ripple and noise are limited to ≤50 mV peak-to-peak at 20 MHz bandwidth. The operating temperature range is -40 to 85°C, with storage from -55 to 125°C. Relative humidity tolerance is 5–95% non-condensing. The device offers ingress protection ratings from IP54 to IP65 per IEC 60529, and efficiency is ≥90% at full load with 230 V AC input. Isolation voltage is 3000 V AC for 1 minute per IEC 61010. Weight ranges from 0.5 to 2.0 kg depending on power rating.

Materials used include semiconductor materials (silicon, gallium arsenide), copper conductors, ceramic substrates, and epoxy encapsulation. These materials support the electrical and thermal performance required for high voltage applications.

For any specific application, verify model-specific values and standards with the legal manufacturer or supplier. The listed parameters are reference ranges and must be confirmed for the actual model and intended use.
Working Principle
The voltage regulator/controller maintains a constant output voltage by continuously monitoring the output and comparing it to a reference. It uses a feedback loop to adjust the internal circuitry—either by linear regulation (dissipating excess power) or switching regulation (rapidly switching transistors to control average output). In high voltage test systems, this ensures that the voltage applied to the device under test remains stable despite fluctuations in the input supply or changes in load. The control circuit adjusts the conduction of power components to correct any deviation, thereby providing a precise and stable voltage for accurate testing.
