RU600


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 :
  • 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.

EA100

Sinee EA100 is Sinee servo drives. Have it combined with its servo motor, there are various applications that can be done when position control is needed. Single mode and mixed mode for speed, position and torque control can be done easily. Equipped with 5-bit 7-segment LED display, 5-bit separate buttons for panel operations, various ports such as external braking resistor, analog monitoring output, RS-232 and RS-485 communication port, upper controller which input/output signals of 36 leads and encoder.

Some applictaions that can be performed :
  • Flame / plasma / paper cutting.
  • Winder, extruder, packaging.
  • Torque tester, dispenser.
  • Engraving, printing, mechanical arm.
  • many others.

EM630

Sinee EM630 Series is a specialized inverters for hoist. It is mainly used in tower crane and bridge crane using its control loop system ability. Equipped with zero servo function to prevent hook glinding when the brake fail. It can also support multiple encoders and over speed protection. With this integrated crane solution, cutomers will surely benefits from cost efficiency.

Note :
For tower crane, overload may occur during instantaneous starting, quick acceleration and decceleration, in this case please use the inverter that is 1 – 2 power bigger.
Capacity selection is available from 22 kw – 45 kw. Other capacities are being developed.

EM600

Sinee EM600 is a newly developed EM303B with additional features to support optional cards, such as SBPG card for closed-loop system, Profi-bus ccommunication card and many other optinal cards. Additional functions embedded completes this series and make it a perfect choice for many speed, position and torque control application.

Some of its important features :
  • Current vector control to to guarantree reliable and stable performance.
  • Soft start and stop to reduce the mechanical motion impact.
  • Specialized braking control function guarantees no sliding.
  • Wide speed regulation scope.
  • Closed-loop system.
  • Profi-bus and mod-bus communication.

EM330D
