Note:

The single phase motor should Not be adjusted to run based on a lower frequency than 80% of its rated frequency for along time, otherwise the motor may fail.
RDDLZ VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.
Single phase VFD Cannot control the motor in reverse, if you want to reverse the motor, refer to the motor nameplate instructions for operation.

Tips: 7 points about variable frequency drive application environment
The variable frequency drive may not be normally operated in any cases, so the user is necessary to have more understanding about load, environmental requirements and the VFD itself. There are seven points should be pay attention to:

Because the motor temperature will be high under long-term and low-speed operation, the fan cooling capacity will also reduce, so it must use high reduction ratio VFD or 6 grade motor to let the motor running in higher frequency.
The variable frequency drive installation site must require the standard environment, or it will easily cause failure or shorten the service life. The distance between VFD and driving motor should not be more than 50 meters, for longer distances need to reduce the carrier frequency or increase output reactor option to function properly.
Type of load and VFD selection: Different load of motor has different requirements of VFD.
Fan and pump is the most common load: They have the simplest requirements of the variable frequency drive, as long as the variable frequency drive capacity is equal to the motor capacity (air compressor, deep water pump, sediment pump, and fast changing music fountain need higher capacity).
Crane load: This type of load is characterized by a great impact on the starting, so it requires a margin of the VFD. At the same time, there will be energy feedback when putting down the weight, so it requires brake unit or share bus.
Uneven load: Some load maybe sometimes light and sometimes heavy, this time should be in accordance with the heavy load situation to select the variable frequency drive capacity, such as rolling machinery, crushing machinery, mixer, etc.
High inertia load: Such as centrifuges, punching presses, cement rotary kiln, these kinds of load have high inertia with large oscillation when starting, and the motor may have deceleration energy recovery. So we should use higher capacity VFD to speed up the starting to avoid oscillation. And we can use the brake unit to eliminate the feedback power.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
