The instruction manual of EYHG-80KVA and EYHG-100KVA hospital street lamp step-down, voltage stabilization and dimming device has an intelligent display, high safety and simple operation; it has a fast reaction speed. When the voltage changes rapidly and fluctuates frequently, the contactless voltage stabilizer can always maintain the output voltage at the required stable voltage value; it has a fast response speed, with lightning surge protection and all protection functions; it is equipped with overload, overvoltage, short-circuit and other protections, with an efficiency of up to99%; it makes the product performance more reliable, reduces the maintenance cost, and effectively ensures the normal operation of the equipment. Rated working current: (A): 20A, 30A, 40A, 45A, 50A, 60A, 63A, 80A, 100A, 120A, 125A, 150A, 160A, 170A, 180A, 190A, 200A, 250A, 300A, 315A, 400A;
Precautions for the EYHG series:
When choosing a voltage stabilization and energy-saving device, it is important to pay attention to the usage range of the common input power supply. Usually, the power voltage regulation and stabilization devices on the market now cannot be used directly. They must first undergo AC conversion before use. Friends only need to inform the manufacturer at the time of purchase, and the manufacturer will customize a suitable power supply usage range for you.
Second, when choosing a voltage stabilization and energy-saving device, you can select it according to the parameters. However, the parameters we currently use are relatively difficult to master. Therefore, everyone must really consider their own situation during the purchase period and then buy a suitable voltage stabilization and energy-saving device. If you choose a smaller one, it may not be enough, but if you choose a larger one, it may be a waste. So Zhejiang Juchuan Electrical Technology Co., Ltd. reminds everyone to have a specific understanding of their own usage situation.

EYHG-80KVA, EYHG-100KVA Hospital street lamp step-down voltage-stabilizing dimming device instruction manual Notes
1. The control of the input power supply and bypass of this equipment must be controlled by the control signal of this equipment. Otherwise, when the equipment detects overcurrent, overvoltage and equipment failure, it cannot automatically cut off the input power supply and automatically bypass, which may cause damage to the equipment.
2. Do not touch any live parts after the product is powered on.
3. Be sure to cut off the power supply before implementing connection or related operations; otherwise, it may cause electric shock or product damage.
4. Be sure to set a circuit breaker at the input end of this product to ensure safety.
5. When installing the energy-saving controller le=300A, please ensure that the box is well grounded; please do not disassemble and modify the product without permission, otherwise it may cause malfunctions, electric leakage, and even fires.
6. Do not reverse the input/output connections, and do not reverse the phase line and the neutral line;
7. Do not place any items on the top of this product;
What are the advantages of the instruction manual for the voltage reduction, voltage stabilization and dimming device for hospital street lights?
It has an intelligent meter that can clearly display data such as voltage and current, and its resolution is very high. The operation accuracy of the membrane keys is also very high, with a very low error rate and high safety.
Secondly, its response speed is very fast. Even if the input voltage fluctuates greatly, the output voltage can always be maintained at the voltage stabilization value set by the user, because its voltage stabilization speed is 20 milliseconds.
In addition, it will not have any impact on the voltage change of any production equipment and instruments, nor will it cause phenomena such as overvoltage, undervoltage and bypass jumping for any equipment. Therefore, it does not have the function of automatically returning to the voltage stabilization state after the voltage returns to normal.
Thirdly, it does not have the compensation function of general power voltage regulation and stabilization devices during the startup process. Instead, it makes corresponding compensation after detecting the output voltage value after startup. This ensures the stable operation of the equipment and also protects the performance of the equipment. On the other hand, it also correspondingly extends the service life of the equipment. This is a blessing for a wide range of equipment. Customers don't have to worry about the frequent maintenance and replacement of the equipment. Moreover, this design also ensures that the equipment will not burn out the electrical equipment due to the phenomenon of too high or too low output voltage during startup.
