CNC machine tool regulator Technical Parameters

Basic indicator		Protective function
Input voltage	380V ± 20% or wide voltage special definition	Overpressure	Output exceeds rated voltage by 10% (adjustable), delay 3-5 seconds to cut off output power
Output voltage	380V±5% selectable	Undervoltage	Output exceeds rated voltage -15% (adjustable), delay 3-5 seconds to cut off output power
Voltage regulation accuracy	1-5% can be set	Delay	2 seconds to cut off the output power
Frequency	50Hz/60Hz	Short circuit	Cut off the output power when the load device is shorted
Strain time	≤0.05s	Overcurrent	When the rated output current is exceeded, the output power is cut off after 3-5 seconds delay.
Stable schedule	When the input voltage changes by 10% relative to the rated value, the stability time is ≤1s.	Reverse phase	When an error occurs in the three-phase electrical phase sequence, the machine alarms and cuts off the output power (settable)
		Missing phase	When there is a phase loss in the three-phase power, the machine alarms and cuts off the output power.
		Bypass	Manual or automatic pass-through device for power supply failure or repair
Other indicators
Additional waveform distortion	≤0.1%	Withstand voltage	The whole machine has no breakdown and no arcing at 2000VAC/min.
Noise	＜55dB	Insulation resistance	Machine to ground≥2MΩ
Efficiency	More than 95% below 50KVA, more than 98% above 100KVA	EM filter device	Can effectively filter harmonic interference of the power grid (optional configuration)
Relative humidity	20%-90%	Lightning protection device	When the power grid changes instantaneously and inductive lightning strikes, it can protect against inrush current (optional configuration)
Way of working	Long-term continuous unattended work	Monitoring interface	With R232, RS485 interface, remote control, remote signaling, telemetry (optional configuration)
