Key Functions of the 30A 36V Electrostatic Descaling Power Supply

The 30A 36V Rectifier for Electrostatic Descaling is engineered to address the most persistent and costly challenges in industrial water systems. Moving beyond temporary fixes, it offers a fundamental solution by leveraging electrostatic technology to transform water treatment from a chemical-dependent chore into a stable, automated process.

Firstly, it directly tackles core operational problems. The system is designed to solve the dual issues of scale formation and Legionella bacteria proliferation in cooling towers, which are primary sources of efficiency loss and health concerns. By preventing these at the source, it ensures your cooling or heating systems perform at their ideal capacity.

The benefits of this prevention cascade throughout the entire operation. With scale inhibited, temperatures stabilize across various applications. This stabilization is crucial, as it prevents equipment malfunctions caused by abnormal temperatures, pipe corrosion due to rust, and flow restrictions from scale blockages. Consequently, production processes benefit from guaranteed stable quality and a significant reduction in defective products.

From a financial and sustainability perspective, the advantages are substantial. By maintaining clean heat exchange surfaces and corrosion-free piping, the rectifier actively extends the service life of critical equipment and infrastructure. This, in turn, drastically reduces maintenance costs and unplanned downtime. The result is remarkably low operating costs, with documented energy savings of up to 54.3% due to restored heat transfer efficiency.

Furthermore, it enhances water quality holistically and safely. The electrostatic field eliminates algae, suppresses bacteria, and neutralizes odors, all without the use of chemicals. This not only optimizes water quality but also removes the handling, storage, and environmental disposal costs associated with traditional biocides and anti-scalants.

Structure

The water treatment power supply primarily consists of a rectifier-filter circuit, a full-bridge converter circuit, a high-frequency transformer, a high-frequency rectifier-filter circuit, an auxiliary power circuit, and a main control unit. The main control unit circuit mainly comprises phase loss protection, temperature protection, overload protection, short-circuit protection, and a PWM circuit with PI regulation.

The three-phase grid voltage is rectified and filtered after passing through the power switch, yielding a smoothed 520VDC supply for the inverter circuit. The inverter circuit primarily employs high-power MOSFET or IGBT modules to form a full-bridge converter. When the PWM output control signal drives the power modules through isolated drivers, two sets of diagonal transistors conduct alternately. This generates a high-frequency pulse voltage in the primary winding of the high-frequency transformer. The secondary voltage is transformed by the high-frequency transformer, rectified, and then supplies energy to the load.

Advanced Features

1. The power supply can operate in either voltage-regulated current-limited mode or current-regulated voltage-limited mode, with seamless switching between the two states.
2. DC output voltage regulation accuracy ranges from 50% to 100%. When input voltage fluctuates by 10% or load changes occur, the output voltage remains stable with regulation accuracy ≤0.5%.
3. Incorporates filtering functionality to prevent interference with instruments during power-up, eliminate grid pollution, and mitigate current inrush phenomena.
4. Phase Loss Protection: Automatically locks out when any phase is missing from the three-phase AC input. Resumes operation automatically after fault resolution.
5. Overcurrent Protection: Automatically enters overcurrent shutdown and alarm state when current exceeds rated value.
6. Short-circuit protection: In case of load short-circuit or internal component short-circuit, the circuit breaker automatically disconnects the power supply.
7. Over-temperature protection: When abnormal temperatures of semiconductor components (e.g., IGBT, Schottky diodes) reach ≥80°C, the electronic switch on the main control board activates, locking the power supply to effectively protect the unit.
