Sinee RU600 is Sinee Regeneration Unit or The Energy Feedback Unit, the full name for “special energy feedback unit of frequency converter ”. It is a kind of special inverter braking unit, is mainly used for large inertia frequency speed regulation system, help renewable electricity back to the grid produced in the process of the motor reducing the speed to help system achieve rapid braking.
Sinee regeneration unit is clasified into 2 types :
1. Parallel energy feedback refers to feedback device and VVVF used in parallel.
2. Tandem energy feedback refers to feedback device and VVVF used in tandem, usually say “active front end rectifier and inverter” AFE(Active Front End)
Technical features :
1. Parallel energy feedback refers to feedback device and VVVF used in parallel.
2. Tandem energy feedback refers to feedback device and VVVF used in tandem, usually say “active front end rectifier and inverter” AFE(Active Front End)
Technical features :
- Low harmonic value less than 5%.
- Power Factor higher than 0.95(usually 0.98).
- Supports two sets of parallel, system expansion, networking group control.
- Dynamic performance for fast transient braking problems.
- Personalized solution to solve lift type equipment overload problem.
- Automatic current limiting.
- Perfect solution in parallel circulation.
- Perfect DC-bus voltage loop control.
