High Reliability, High Speed Correction (5000V/Sec.), High Inrush Current:
KHZ-SW Series, Static Voltage Regulators are fully microprocessor, thyristor controlled and works with digital technology. When there are abnormal conditions like over voltage, low voltage, overcurrent, over-heat and output short-circuit, stabilizer protects itself and its load. RFI and EMI filters are available as standard. KHZ-SW Series, Static Voltage Regulators instantly feel the change in the mains voltage and set the output voltage in the range of 2% within 20 milliseconds. KHZ-SW Series, Static Voltage regulators perform voltage regulation with static elements (thyristor) in the ZERO TRANSFER logic with STEP_UP / DOWN method. Current transfer is zero-pass. Therefore, it does not contain harmonics.

Product Features:
Large screen LCD display: Adopting a VA large screen LCD display, it can dynamically display working voltage, working current, and various working states.
Independent Phase Regulation: Ensures balanced three-phase output for precision equipment protection.
Product characteristics: The voltage stabilization speed is as fast as 40ms, the whole machine has no contacts, anti-interference, no mechanical faults or carbon brush wear, and is maintenance free. Three phase voltage is independently regulated to ensure balanced output voltage. Effectively protect the electrical safety of precision equipment.
Adjustable voltage stabilization accuracy: The preset voltage stabilization accuracy of this machine at the factory is ± 1%. Adjustments of ± 1%, ± 3%, and ± 5% can be made for different load requirements.
Manual pressure regulation function: According to production needs, this voltage regulator can set the voltage arbitrarily within the range of ± 7% of the rated voltage value for use by different electrical equipment.
Automatic bypass function (optional): Equipped with automatic bypass function, when the voltage regulator fails, it will automatically switch to mains power operation without affecting production operations.Or when the voltage regulator malfunctions or experiences overvoltage, undervoltage, overload, etc., circuit breaker protection can be implemented (automatic bypass is optional).
Output high and low voltage protection function: When the monitoring circuit detects that the output voltage exceeds the upper or lower limit, the voltage regulator automatically switches to mains operation without affecting production operations.
Phase loss/phase mismatch protection function: When the monitoring circuit detects a phase loss in the input or output voltage, the voltage regulator will automatically cut off the output and sound an alarm.
Output delay voltage stabilization function: When the voltage regulator is turned on or restored from a protective state, it will not immediately stabilize the voltage. Instead, it is necessary to wait for the user to confirm that the mains power is normal before stabilizing the voltage to ensure that the load equipment is not damaged.
Automatic output function: The system is preset for automatic output. When the voltage regulator is connected to the mains power, the system detects that the power grid is normal and delays the automatic voltage regulation output for 30 seconds.
Modular design, easy to replace and repair: Adopting modular design, the voltage regulator circuit and monitoring circuit are independent of each other, and all components are standardized. Assembly, debugging, replacement and maintenance are simple and fast.
Super strong load-bearing capacity: When there is a short-term overload or a short circuit in the load, the transformer will not be damaged, avoiding the coil from catching fire and burning out due to the short circuit.When overloaded by 150%, it can withstand 90 seconds, and when overloaded by 200%, it can withstand 20 seconds.
