Product Details
Parameters of voltage stabilizer for CNC machine tool equipment
Basic indicators of SBW series voltage regulator SBW voltage regulator protection function
Input voltage 380V ± 20 ℅ or wide voltage specially customized single-phase 220V ± 20 ℅ overvoltage output exceeding rated voltage by 10 ℅ (adjustable), delay for 3-5 seconds to cut off output power supply
The output voltage is within 380V ± 5 ℅, and single-phase 220V ± 5 ℅ can be selected. Under voltage output is below the rated voltage by -15 ℅ (adjustable), and the output power is cut off after a delay of 3-5 seconds
Voltage stabilization accuracy 1-5 ℅ can be set with a delay of 2 seconds to cut off the output power supply
When the load device is short circuited at a frequency of 50Hz/60Hz, cut off the output power supply
When the strain time is ≤ 0.05S and the overcurrent exceeds the rated output current, the output power supply will be cut off after a delay of 3-5 seconds
When the stable time input voltage undergoes a 10% step change relative to the rated value, and its stable time is ≤ 1S, and there is an error in the three-phase electrical phase sequence, the machine will sound an alarm and cut off the output power supply
When there is a shortage of three-phase power, the machine will sound an alarm and cut off the output power supply
When the voltage regulator malfunctions or is under maintenance, the bypass is equipped with a manual or automatic power supply through device
Other indicators of SBW voltage regulator
Additional waveform distortion ≤ 1 ℅ Voltage resistant machine to ground 2000VAC/min without breakdown or arcing phenomenon
Noise level ＜ 55dB, insulation resistance of the whole machine to ground ≥ 2M Ω
Efficiency below 50KVA is greater than 95%, and above 100KVA is greater than 98%. The EM filtering device can filter out harmonic interference from the power grid (optional configuration)
The lightning protection device with a relative humidity of 20 ℅ -90 ℅ can provide good surge current protection effect when the power grid changes instantaneously and induces lightning strikes (optional configuration)
The working mode can be continuously unmanned for a long time. The monitoring interface has RS232 and RS485 interfaces to achieve remote control, remote signaling, and telemetry functions (optional configuration)
The SBW series high-power fully automatic compensating voltage regulator is a new generation of energy-saving power regulator developed and produced by our company based on similar international products and China's national conditions. It is equipped with overvoltage, undervoltage, delay, and fault protection functions, and has the advantages of large capacity, high efficiency, wide voltage regulation range, high accuracy, strong protection function, no waveform distortion, small size, light weight, reliable operation, and easy maintenance.
Scope of application:
Posts and telecommunications, shopping malls, elevators, schools, printing, securities and other places that require normal voltage, as well as large and medium-sized industrial and mining enterprise workshops, some power supply and important equipment and single machine matching.
Usage conditions:
The three-phase compensating voltage regulator should be used indoors, and the normal operating conditions are:
1. Do not use excessively high loads;
2. Please use sufficient wires;
3. Please be careful to connect the input voltage of the voltage regulator and the input of the instrument equipment;
4. The rated voltage of the instrument and equipment should be consistent with the output voltage of the voltage regulator;
5. Please ensure that the input voltage is consistent with the voltage regulator's stabilizing range;
6. Altitude not exceeding 1000m
7. Relatively moderate: ≤ 90%
8. The installation site should be free of gases, vapors, chemical deposits, dust, dirt, and other explosive and corrosive media that seriously affect the insulation of the voltage regulator;
9. The installation site should be free from severe vibrations or bumps
10. Any special usage conditions that do not comply with the above regulations should be determined through consultation between the user unit and our factory
