Key Features

This product is a professional electrocoagulation power supply built on advanced pulse power technology. Breaking through the limitations of traditional DC electrocoagulation, it outputs precise single-pulse power with a high current of 100A and a high voltage of 500V. While efficiently removing heavy metals and recalcitrant organic matter, it significantly suppresses side reactions and reduces electrode passivation, ultimately achieving the triple goals of energy saving, improved treatment efficiency, and reduced operating costs. It is an ideal choice for upgrading electrocoagulation technology.

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.

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.
