Based on automatic control, Linglang has mastered the core technology of AC and DC frequency conversion through continuously technology innovation and extensive international technical exchanges during the 20 years development. Its independently developed LL500 high performance vector frequency conversion series, LL310 chemical industry frequency conversion series, LL510A/B elevator-specific frequency conversion series and Y510 asynchronous servo energy-saving series, the technology is synchronized with international standards. Meanwhile, to meet the needs of domestic environmental and different industry’s application, the company has further strengthened the products’ reliability and environmental practical design so as to better satisfy the high, medium and low-end market requirements.

At present, the general frequency conversion and servo product series are improved. The LL500 vector frequency conversion series includes the single-phase 220v 0.4-2.2KW, 380V 0.4KW-175KW; LL310 series is from 380v 0.4KW to 450KW; LL510A / B series includes 380V / 37KW, 380W / 75KW, and LY510 server series is divided into 380V 15KW-132KW.
