Hope Senlan Technology Co., Ltd. is a national key high-tech enterprise dedicated to the research and development of high, medium, and low voltage frequency conversion technology, as well as the design, development, production, sales, and service of related products. It is one of the earliest enterprises in China to engage in frequency conversion technology research and application, and one of the largest frequency converter research and manufacturing bases in China. It is also one of the first enterprises in the frequency converter industry to obtain the title of "Chinese Famous Brand" product and the recognition of "Chinese Famous Trademark".
Chengdu Hope Senlan Company launched a new generation of HOPE800 series high-performance vector control frequency converters, SB150 compact low-voltage frequency converters, high protection level SB71 series dustproof frequency converters, and SBH series high-voltage frequency converters for belt conveyors in 2015.
The HOPE800 series is a high-performance vector control frequency converter with a power supply voltage of 400V and a power range of 0.4-375kW. It integrates high-precision rotor field oriented vector control algorithm and has 290% instantaneous torque control capability. The unique multi-mode PLC operation function is particularly suitable for pipe pile manufacturing and industrial washing equipment applications. Powerful process PID function: two sets of parameters, multiple parameter transition modes, and multiple correction modes, which can meet the tension and synchronous control needs of industries such as wire drawing machines, textiles, papermaking, printing and dyeing. Equipped with free PID function, it can replace external PID controllers, and is suitable for multi-stage speed function: providing encoding, direct, stacking, and number selection methods, especially suitable for applications in the HVAC industry.
The SB150 series frequency converter is a refined and practical frequency converter launched by Senlan, with a power supply voltage of AC220 or 380V and a power range of 0.4-1.5kw. It has a delicate and compact appearance, a refined and complete circuit, simple and practical functions, and clear and reasonable menu division. The core of SB150 integrates Senlan's high-performance optimized space vector variable frequency conversion algorithm, which has advanced functions such as automatic torque enhancement, slip compensation, oscillation suppression, tracking start, stall prevention, precise dead zone compensation, automatic voltage regulation, process PID, and automatic carrier frequency adjustment. Can be applied in medicine, food, textiles, printing and dyeing, washing, cables, packaging, machinery, ceramics, water supply, centrifuges, conveyor belts, dehydrators, etc.
