ALSTOM ALSPA MV1000 Intelligent Variable Frequency Drive

Power filter and ferrite ring: meet the EMC requirements of EN 61800-3 for public power grids, and can enable radiated interference to reach EN 55011 Class A or B (motor cable ≤ 50m for Class B). The ferrite ring is installed at the output end of the frequency converter to reduce the high-frequency radiation interference of the motor cable.

Motor Reactor: Used for long cables (>100m shielded cables) or parallel drive of multiple motors to limit the charging current spikes caused by cable capacitance and reduce the load on the frequency converter. Can replace motor filters.

Motor filter: protects the motor from transient overvoltage and high voltage rise rate (dv/dt). Typical applications can limit the peak voltage of the motor terminal to below 1000V (400V grid, 100m cable). Specially recommended for old motors or motors with unknown insulation.

Braking module (BM12): Built in braking resistor, suitable for intermittent and short-term braking of large inertia loads. Continuous braking power of 100W, peak value of 12kW, maximum load cycle of 0.5%/500s.

Brake chopper (BC32): without brake resistor, requires external resistor, suitable for frequent or continuous braking needs. Continuous braking power of 19kW, peak power of 32kW, maximum load cycle of 1%/100min.

Braking resistor: available in multiple specifications, used in conjunction with a braking chopper.

Power supply and feedback module (PS12/24/45): realizes energy feedback to the grid and DC bus power supply function. When ALSPA MV1000 is powered through a DC bus connection, there is no need for power reactors and filters. The PS module can feed back braking energy to the power grid, improving system energy efficiency.

PC interface RS232/RS422: Used to connect a PC to run ALSPAPCS software, and can be used simultaneously with a keyboard or fieldbus coupler.

CANopen component: Using standard CAN interface, it can connect CAN PC interface, CAN Mini PLC, CAN I/O expansion module to achieve distributed control.
