- 3. KE300A-04 single phase output inverter KE300A-01 single phase output inverter is a kind of inverter special for single phase motor. It is based on the advanced control platform of KE300A, combining the unique start and control requirements of the single phase motor, and using a brand-new flux vector control technology to achieve true two phase orthogonal 90° flux vector control. With high start torque and high efficiency of overall unit, it can be widely applicable to single phase asynchronous motors, such as fans, pumps, power tools, etc. Product feature 01 02 03 04 Orthogonal 90° flux vector control technology Use brand-new flux vector control technology to achieve true two phase orthogonal 90° flux vector control, with high start torque and high efficiency of overall unit. High starting torque and fast dynamic response The new control algorithm brings better low-speed stability and stronger low-frequency loading capacity. Dynamic response time <20ms, and output 150% start torque when running at 0.5Hz. Strong overload capacity 150% rated current/1 minute, 200% rated current/3 seconds. Non-stop when instantaneous power off With the capability of non-stop when instantaneous power off, ensuring the system continuously operate without tripping in case of instantaneous power off. 05 06 07 08 Solid EMC design and lightning protection design Solid EMC and lightning protection design make system run more stably. Fast current limiting function With fast current limiting function, easily responding to the conditions with sudden load, greatly reducing the probability of inverter’s frequent over-current fault. Perfect protection function Overvoltage/ undervoltage protection, overheating protection, ground protection, short-circuit protection, overcurrent protection, overload protection and so on, all of the functions ensure the system more secure and reliable. Easy installation and commissioning Special design for single phase asynchronous motor, no need to remove the start capacitor and running capacitor of motor, easy to install and commissioning. 04 03

Wiring diagram MICNO KE300A-04 single phase output inverter has two methods of motor wiring. 01 02 Remove capacitor No remove capacitor Remove the capacitor of single phase motor, then connect the common terminal of two windings (single motor has two windings) to the V phase of inverter, and then connect the other terminal of two windings to the U & W phase of inverter separately. Power on the inverter and set P9-13=0, start the inverter and observe the current. If the current is too large, please stop and set P0-15=10, P1-02=160. If the current still too large, please stop and switch the connection of U & W phase. The motor input lines (L, N) are connected to the inverter V, U or W. Usually the default is V must be connected, U or W is optional. Power on the inverter and set P9-13=0, start the inverter and observe the current. If the current is too large, please stop and set P0-15=10, P1-02=160. If the current still too large, please stop and switch the connection of U & W phase.
