Core Technology

Sharp a drive control applications in various industrial machines achieved good performance and word of mouth, especially in the field of "Marine", has a wealth of design experience, good reputation, and a classic case, won the major design institute, shipyard and owner's approval, and keep long-term cooperation relationship with them.

New space vector technology
Excellent vector algorithm ensures low frequency and high torque under the premise of minimum switching loss, high efficiency of grid voltage and optimized sine wave output, resulting in reduced working noise and reduced heat.
Special software dead zone compensation
The dead time is the culprit of the low frequency pulsating torque of the frequency converter. Renergy's unique software dead time compensation can maximize the smooth torque under low frequency extreme conditions.
Excellent speed tracking self-starter with no speed sensor
Can start the motor in operation to ensure the smooth operation of the user equipment, the Renergy product can automatically identify the speed and realize the steady speed tracking.
Automatic energy saving operation
Unique software power factor regulation, according to the change of load, dynamically adjust power factor, save more energy.
Voltage fluctuation suppression
The dynamic automatic voltage control (AVC) function ensures that the output voltage fluctuation is less than or minus 5% when the input voltage fluctuation is plus or minus 20%.
Friendly human-machine interface with flexible input and output interface
LCD Chinese and English display, provide 8-channel digital input, 2 analog input, 3-channel digital output, 2-channel analog output; Eight segment user can program run, electric potentiometer set mode.
Dc power supply, save the security power investment.
Built-in flexible PWM energy consumption braking, the user chooses the appropriate brake resistance to realize energy consumption braking easily.
Perfect protection function
It has the protection design such as overpressure, overcurrent, undervoltage, IGBT short-circuit, inverse time overload and so on. Besides, it can be safely protected under load short-circuit and grounding.
