SBW-SK series laser and CNC machine tool special voltage regulator is based on years of experience in designing and manufacturing voltage regulators, according to the different needs of laser equipment and CNC machine tool users for power safety, customized for users in this industry for a series of industry-specific voltage regulators. The special voltage regulator for laser equipment and CNC machine tools has anti-high-frequency interference, anti-electromagnetic and anti-surge performance, not only has the characteristics of split phase adjustment, rapid adjustment, no noise, etc., and the special voltage regulator for laser equipment and CNC machine tools has perfect protection functions.
Basic indicators of voltage regulators for laser and CNC machine tools | Protection function | ||
Input voltage | 380V± 20% or wide voltage is specially defined | Overpressurized | If the output exceeds the rated voltage by 10% (adjustable), the output power supply will be cut off with a delay of 3-5 seconds |
Output voltage | 380V ±5% can be selected | Underpressure | If the output exceeds the rated voltage by -15% (adjustable), the delay will be 3-5 seconds to cut off the output power |
Voltage regulation accuracy | 1-5% can be set | Time delay | Cut off the output power supply for 2 seconds |
frequency | 50Hz/60Hz | Short circuit | When the load equipment is short-circuited, cut off the output power supply |
Response time | ≤0.05s | Passing through | When the rated output current is exceeded, the output power supply is cut off with a delay of 3-5 seconds |
Stabilization time | When the input voltage changes by 10% relative to the rated value, the stability time ≤ 1s | Reverse phase | When there is an error in the three-phase electrical sequence, the machine alarms and cuts off the output power |
Lack of phase | When the three-phase power is out of phase, the machine alarms and cuts off the output power | ||
Bypass | When the voltage regulator fails or is repaired, it has a power manual or automatic DC device | ||
Other indicators | |||
Accessory waveform distortion | ≤1% | Pressure resistance | The whole machine has no breakdown and no flying arc phenomenon at 2000VAC/min to the ground |
Noise | ＜55dB | Insulation resistance | The whole machine has a ground ≥ of 2MΩ |
efficiency | More than 95% for less than 50KVA, more than 98% for more than 100KVA | EM filtering device | Effectively filters out harmonic interference from the grid (optional configuration) |
Relative humidity | 20%-90% | Lightning protection device | When the power grid changes instantaneously and induces lightning strikes, it can play a role in inrush current protection (optional configuration) |
Working methods | It can work continuously unattended for a long time. | monitoring interface | With R232 and RS485 interfaces, remote control, remote signal, and telemetry functions (optional configuration) |
