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.

...t effective and longest-lasting, chemically treated and coated in a thermosetting resin to resist the growth of algae, holds up to frequent cleanings, and prevents dirt and other particles from penetrating into the substrate.
SAFE AND EASY OPERATION: With Cool-Space's variable-speed controls, maintaining the perfect temperature for your space is as simple as turning a dial.
For convenience, all Cool-Space models feature locking swivel casters, automatic low-water shutoff, and an easily accessible drain plug.
POWERFUL AND EFFICIENT MOTORS: Cool-Space coolers feature virtually silent direct-drive motors and variable-speed controls that allow you to deliver precise cooling for a fraction of the cost of traditional A/C.
Cold Front motors offer the perfect combination of power and efficiency to keep your space comfortable.

True-RMS clamp meter: This voltage meter can accurately measure AC Current, AC/DC Voltage, Frequency or Duty Cycle, Resistance, Capacitance and also provides Diode, Continuity and Temperature tests. True RMS for accurate measurements on non-linear loads. Easy to use for labs factories and household..
LowZ & LPF: Low input impedance helps prevent false readings due to ghost voltage. Low Pass Filter (LPF) for accurate measurement of variable frequency drive signals when measuring motors and transformer. To measure the current you need to clamp the meter around one of the wires and not the whole power cord..
NCV Defection Function: Non-contact voltage detection effectively check electrical status through measuring EM field intensity without touching any wires.
The NCV button lies on the right side. Simply place your thumb on it and push..
Multi-function: Two-color backlit LCD Display - When the voltage > 80V, the current > 3A, the LCD backlit screen turns red to warn you of high voltage/ LED Flashlight / Temperature Measurement for liquids and air conditioning ports included K-Type Thermocouple / Low Battery Indication / Auto power off after 15 minutes inactivity..
