ATO 110v vfd, single phase 110v/120v input, single phase or three phase 220v output, achieve to run 220v AC motor on single phase 110v/120v power supply.
【Voltage& Frequency】Input voltage: 1 phase 120V AC ±15%, Input frequency: 50Hz/60Hz,Output voltage: 1 phase or 3 phase 220V AC ±15%, Output frequency: 0.00~400.00Hz.
【APPLICATION】ATO 7.5 hp 5.5kW variable frequency drive Can be widely applied to drive the AC motor, such as fans, pumps, power tools, etc.
【TIPS】 To protect the variable frequency drive and Motor, you need an upstream protection, add a line-choke upstream the VFD, this will reduce the current transients seen by the input of the VFD.
【CUSTOMER FIRST】If you have no experience in driving a VFD, be sure to refer to the instructions before operating a VFD.If you are not sure about the size or have any issue about the product or service, please don't hesitate to email us. We will answer you within 12h.

3-Phase Voltage Monitoring Relay AC 220-440V Phase Sequence Protection Small Size Protection for Industry Applications
Dynamic phase loss, static phase loss protection: refers to the phase failure of any phase when the protected device is in the running state or non-operating state. The indicator light is in the form of red light and priority.
Wrong phase protection: A protection measure to prevent the phase sequence of L1, L2, L3 three-phase AC power supply from being connected incorrectly. Instant action. The indicator light is in the form of yellow light..
Voltage Unbalance Protection: Refers to a voltage imbalance that will affect the safe operation of the device. When the voltage imbalance rate is higher than 8%. The form of the indicator light is: the lack of phase red light is on, and priority..
Delay protection: When there is a fault, the monitor will delay after 1~2 seconds, and the relay will release..
The protection function of the monitor is not affected by the current of the line or load, the inrush current, the unbalanced current and the nature of the load. Long-term work with full performance and full climate. Power consumption is no more than 2W..
