JL930 series high-performance high-power frequency converter

JL930 series high-performance vector frequency converters, with high reliability, high environmental adaptability, excellent control algorithms and high-quality, high power density design, make the product have a significant improvement in ease of use and maintainability. The products are widely used in plastic machinery, textile, machine tools, food packaging, environmental protection, chemicals, building materials, ceramics, ball mills, fans, water pumps, air compressors and other industries.

Superior performance

0.25Hz/150% rated torque in low-speed and high-torque SVC control mode 0.00Hz/180% rated torque overexcitation control in FVC control mode, reducing braking time overload capacity 150% rated current 60S

Easy to operate

The detachable LED operation panel is easy to operate, easy to maintain, the fan can be freely disassembled and debugged, the structured parameter group is simple and easy to understand, the function is intelligent, the current is automatically limited, and the speed is automatically tracked

Stable and reliable

System safety and reliability test: perfect protection functions (power-on short-circuit protection to ground, input and output phase loss overvoltage, overcurrent protection, etc.)

It can be widely used in applications with high requirements for speed control accuracy, turnstile response speed, and low-frequency output characteristics.

■Three speed control modes: vector control without speed sensor (SVC), vector control with PG (VC>, V/F control, torque control;
■Automatic tuning of static and rotary motor parameters;
■ Realize high-precision closed-loop speed control and torque control;
■ Adopt dual CPU control platform (DSP+ARM);
■Load: 150°/. Rated current 60s, 180% rated current 10s;
■ Starting cabinet: no PG arrow maximum control 0.5Hz/150% (SVC); PG Arrow Control 0Hz/180% (VC);
■ Speed control range: 1:100 (SVC), 1:1000 (VC>;
■ Carrier frequency: 1.0kHz ~ 16,0kHz;
■Torque control function: provide a variety of torque setting sources;
■Simple PLC, multi-speed and PID control, swing frequency function;
■Automatic voltage adjustment: it can automatically keep the output voltage constant when the grid voltage changes;
■ Provide RS485 serial communication interface, using standard Modbus communication protocol;
■ 0.4-22KW built-in brake unit for each specification, (30KW built-in brake unit needs to be equipped) If you need to stop quickly, you can directly connect the brake resistor;
■ It has a power-down reset function to ensure the continuity and efficiency of production.
