1. Avoid violent vibration, prevent corrosive gas and liquid from entering, prevent from being irrigated, and place it in a ventilated and dry place. Do not cover with fabric to obstruct ventilation and heat dissipation.
2. Please use a three-plug (grounded) socket, and the grounding screw on the machine must be properly grounded, otherwise, the case will be charged with a test pen. This is caused by the distributed capacitance induced electricity, which is a normal phenomenon. You can use the grounding wire to eliminate it. If the case is seriously leaking and the measured insulation resistance is less than 2MQ, it may be that the insulation layer has been damp or the circuit and the case are short-circuited. You should find out the cause and eliminate the fault before using it.
3. The 0.5~1.5KVA low-power voltage stabilizer uses a fuse for over-current and short-circuits protection. The 2~40KVA voltage stabilizer acts as a circuit breaker for over-current and short-circuits protection. If the fuse is often blown or the circuit breaker frequently trips, it should be Check whether the electricity consumption is too large.
4. When the output voltage exceeds the protection value (the phase voltage protection value is adjusted to 250V±5V when leaving the factory), the stabilized power supply is automatically protected, the output voltage of the stabilized power supply is cut off, and the overvoltage indicator is on(Importance of the Integrated Voltage Switching Voltage Regulator). The user should immediately shut down and check the grid voltage or If the voltage stabilizer automatically cuts off (input but no output), check whether the mains voltage is higher than 280V. If it is lower than 280V, check whether the regulator is malfunctioning. Use after finding out the reason.
5. If the output voltage of the regulator deviates too much from 220V, please adjust the potentiometer on the control board until the output voltage is normal (the input voltage cannot be adjusted if it does not reach the voltage regulation range).
1. Smart meter display "Smart meter displays line voltage, phase voltage, current in real-time. Clear, accurate, high resolution, membrane button operation, safe, and reliable.
2. Wide range of application and wide voltage stabilization range, which can meet the requirements of sites and equipment with poor power grid quality and large voltage fluctuation range.
3.Low loss: minimum power loss, the no-load loss is less than 0.5%, saving users a lot of electricity bills.
4.Complete protection functions, equipped with overload, overvoltage, under-voltage, short circuit, and other fault display and protection functions to ensure the safe operation of the voltage stabilizer and load.
5. With the preset function, the protection limit can be set at will.
6. Strong overload capacity, solicit high-quality components, which can be used continuously under 80% rated load conditions, and can withstand an instantaneous overload 2 times without damaging the machine.
7. Strong applicability, strong applicability to power grids and loads, and can work reliably and continuously under various harsh power grids and complex load conditions.
8. No distortion, adopting current zero-crossing switching technology, there is no interruption in the switching process, no surge current is generated, and the waveform is not distorted.
9. The bypass function is easy to maintain: the mains output voltage can be changed according to the user's required voltage on the basis of voltage stabilization.
