KDE is a trademark with the main product lines such as inverters control asynchronous motors, electrical measurement devices such as multi-function meters, current transformers, digital power meters, analogue types, regulators, temperature control, set timers , signal converters.
KDE inverters are manufactured in Shenzhen – China, with product ranges for common or special applications.
KDE200 economical inverter series, V / F basic control mode are used in simple applications for fan load, small capacity pumps, grinders.
Economic inverter KDE500M, compact design, power range up to 4kW, has many different control modes such as, V / F, Sensorless vector, Speed or torque mode, used in control problems blower, water pump, receiver wrapped in paper and plastic bags
The powerful control KDE200A series integrates multiple V / F control modes, sensorless vector, speed, torque and additional closed-loop control with the encoder feedback signal for use in simultaneous, stable problems. motor speed regulation.
KDE300A is a prominent product line with powerful control features, hardware design using components from world-famous brands such as control chips of Texas Instruments , Infineon semiconductor valves, optical isolation of Avago. Software is the highlight of the product.
KDE300A has a new software which is different from other inverter software originating from China. The software is optimized for control, suitable for many application problems due to its control and operation features such as V / F, sensorless vector, speed, torque and additional closed-loop control with signals feedback from encoder. In here, the software development process has been optimized so that the inverter can be used with many other applications, such as closed-loop control used in elevators, used in cranes, hoists and hoists tower, without the need for other special types of inverter, or in plastic molding machines, woodworking machines, Ceramic bricks.
Only with a control software on the inverter, engineers can easily install for specific applications with the help of external data acquisition control cards such as encoder card, plastic injection card, or the brake.
The product has built a communication port with Rs485 physical transmission line and Modbus RTU protocol, enabling integrated engineers to build control and monitoring software on PLCs, HMIs, PCs, conveniently for data storage, changing control parameters, saving the use of analog modules when used with PLCs with digital input ports that receive high-speed pulses. It can also be used as a frequency setting point or used as a counter, easily switching between control modes, changing setpoint, running PID mode, via DI inputs, with digital output, it is possible to set the relay delay, turn on the alarm when an error occurs. In closed-loop control mode with encoders, KDE300A supports many types of encoders, ABZ, ABZUVW, Sin / cos, explicit error description codes, with detailed instructions on error situations and how to fix them.
Especially in the near future we will deploy this product line for use in plastic injection machines. This product line can control PMSM motor, which helps to reduce power during plastic injection machine operation.
We are pleased to be one of the distributors of the KDE inverter line and trained in installation, technical advice and warranty in Vietnam.
