TECO MV510 VFD Series
TECO MV510 general-purpose medium and high voltage inverter
High-quality power input: Through the phase shift of the secondary winding and the multi-pulse diode rectifier, the isolated power can be obtained and provided to the battery. (6.6Kv 36 pulses, 11kV 54 pulses) Using multi-pulse rectification technology can greatly eliminate harmonic current.
Nearly perfect power output characteristics: MV510 universal medium voltage driver adopts multi-stage cascading technology, which greatly eliminates the output harmonic content. The output waveform is almost a perfect sine wave (see Figure 2 and Figure 3). Compared with other high-voltage and high-power MVDs, it has the following advantages: no additional output filter device is required; direct drive of general high-voltage synchronous or asynchronous motors, the motor temperature will not rise; no need for motor derating operation; no dv for motor and cable insulation /dt damage; no torque ripple caused by harmonics, which can prolong the service life of motors and mechanical devices; when the voltage drop is within the allowable range, there is no limit to the cable length;
The man-machine interface has powerful functions: touch screen system control; monitoring operation status; power unit temperature and status monitoring and control; low voltage operation function test; 100 strokes can be recorded; password setting; remote control; emergency stop.
Flexible and convenient installation: According to customer requirements, MV510 can be installed on the top, bottom or both with any possible inlet and outlet.
Other functions and features: Overload and overcurrent protection; phase loss and grounding protection; overvoltage protection; overheating protection; current limiting function; control power supply interlock protection; two sets of control power supply redundancy; power battery bypass function (optional) ;Cabinet door opening alarm function; phase lock function (optional); frequency conversion and power frequency synchronous switching function (optional); motor soft start, no impact on mechanical equipment and network; high efficiency: under rated conditions (excluding transformers) ) The MVD efficiency is greater than 98%; the power unit communicates with the controller through optical fiber, which is completely electrically isolated; the built-in PID regulator realizes closed-loop control. Various communication methods with the host computer, isolated RS485 interface, standard MODBUS; RTU communication protocol, PROFIBUS DP (optional), industrial Ethernet communication protocol (optional); accurate fault records, query information, and locate faults; compact structure, Reasonable layout (can be designed by customers); AVR (automatic voltage regulation); flying start function.
