Products Description

Medium voltage variable frequency drives Product Structure Sinopak MVVFD includes integrated structure and split-type structure based on capacity. The integrated structure is adopted in low capacity MV VFD and the split-type structure is adopted in high capacity MV VFD. In terms of an integrated machine, which is compact in size, phase-transformer, power units, control systems, and power frequency bypass are fully integrated into one cabinet; In terms of a split-type machine, phase-transformer, power units, control systems and power frequency bypass are assembled in separate cabinets in which are combined on the spot. Technical Parameters Medium voltage input 3KV, 3.3KV, 4.16KV, 6KV, 6.6KV, 10KV, 11KV (-20%~+15%) 50/60 Hz±10% Medium voltage output 0~Rated voltage 0~50/60 Hz, 0.01 Hz Multilevel PWM sin wave, total harmonic distortion (THD) < 4% Performance Inversion efficiency at an rated load > 98.5%, overall efficiency (including the transformer) > 97% Power factor (within the range of speed regulation) > 0.95, power factor (at a rated load) > 0.97 Overload capacity: 110%: long-term stable operation, 120%: 1 minute, 150%: 2 seconds, and 160%: prompt protection Allowable outage duration: 200 ms (and longer under light load) Mean time between failures: > 100,000 hours Control mode: flux optimization and control with space vector PWM Acceleration/deceleration time: 1 to 3,600 seconds Switching quantity input/output:11-way/10-way Analog input: 4-way (optional: 0 to 5 V, 4 to 20 mA) Analog output: 3-way (optional: 0 to 10 V, 4 to 20 mA ) Communications: RS485 interface, Modbus-based (optional Profibus-DP and Ethernet interfaces) Control power supply: Single-phase 220 V AC, 5kVA Excitation control ( dedicated for the synchronous motor) Automatic excitation control, manual excitation control, multi-stage speed excitation control, and external excitation control for the MVVFD Environment: Operating in indoor environment without explosive or corrosive gases, conductive dust, or oil fog Operating ambient temperature: 0 degree~+45 degree Storage and transportation temperature: -40 degree ~+70 degree Ambient humidity: < 90% (No condensation) Operating altitude: Derating required for an altitude greater than 1000 meters Protection function: Overcurrent, overload, short circuit, three phase current unbalance, immediate electric outage, input/output phase loss, overvoltage, undervoltage, body overheat, transformer overheat, shutdown due to external fault, and power unit auto bypass Cooling mode: Forced-air cooling User interface: An 10-inch Human Machine Interface Protection grade: IP31
