Renda mini inverter is widely used in small constant pressure water supply system, industrial machinery, industrial automation control and other applications. Such as: baler, dumpling machine, treadmill, agricultural breeding temperature and humidity control fan, food processing mixer, grinder, drilling machine, small hydraulic lathe (3HP) or less, elevator (2HP), coating machine, small milling machine (surface processing 3HP), injection molding machine robotic arm (clamping), woodworking machine (two-sided planer), welt machine, elastic machine and so on.
Inverter products are one of the electrification products that Renda Group has gradually grown into after 2006, and has gradually developed into the company's core products.
Renda inverter has the following characteristics:
Excellent control performance
Excellent software control platform, unique vector control algorithm;
Renesas motor control 32-bit high-speed CPU;
True current vector control, realizing the decoupling control of torque current and excitation current;
No PG vector control [subdivided into two types), there are three control modes of PG vector control and V/F control;
Real speed tracking function, good linearity of torque control (adjustable from 0%--200%, linear increase or decrease of torque, no sudden flying and other phenomena):
Dynamic torque current control, fast response to load changes;
Accelerated current suppression function, special current algorithm does not affect the starting torque J to avoid failures caused by large starting current of some equipment;
Good low torque characteristics, open loop vector 0.5 H z can output 150% torque, to meet the low frequency large torque requirements of machine tools, lifting and other industries;
Strong overload capacity, 180% current can last for 20s (domestic general 10s);
High speed control accuracy, convenient to achieve high-precision synchronous control.
Powerful features
Multiple frequency composite given functions;
Open-loop/closed-loop torque control function, support torque mode/degree mode online switching;
. PID function provides two sets of proportional integration parameters, PID output range can be set arbitrarily, support sleep function;
. V/F control provides V/F separation control function;
Sag control function of automatic load balancing:
Simple servo fixed length control function;
. R5-485 communication interface, support MODBUS-RTU communication protocol, provide multi-machine synchronization function;
Automatic energy-saving operation function;
Automatic re-start function when power down;
A variety of expansion cards can be configured, and the use is more flexible.
Keyboard user parameter copy function;
Rich fault protection and operation monitoring functions.
Super adaptable
Unique IGBT drive circuit, obtained national invention patent, so that the power device works more reliable;
All models of the whole series have phase-to-phase short circuit protection to adapt to more harsh environments;
Wide voltage working range: 304VAC-456VAC;
. PCB spraying adopts German imported conformal paint;
Optimized EMC design, suitable for strong interference working environment
.100% incoming inspection;
Automated single board and whole machine testing to ensure that there are no test blind spots;
The veneer and the whole machine are aged at high temperature.
Humanized structural design
Full series of independent air duct design, heat dissipation duct and electrical part separated. Reduction, failure rate of electrical parts;
Compact design, small product volume through thermal design and simulation, body type is only about 70% of the same power of mainstream brands;
European style design, straight shape. Save the installation width to the greatest extent and save cabinet space for customers;
The human-machine control interface has obtained national patents;
Graphical keyboard designed with bronze elements, in line with most people's operating habits;
The operation panel double crystal head standard RJ45 interface, enhance the communication anti-interference ability, convenient for customers to epitaxy;
The chassis material is solid, a large number of aluminum-zinc coated sheets and spraying protection design not only ensure good grounding and shielding performance, but also take into account the anti-corrosion energy of the product;
A full range of DC cooling fan design to reduce the failure of the heat dissipation system caused by AC fan failure.
