FVCA01.2-18K5-3P4-MDA-LP-NNNN-02VRS

The Bosch Rexroth Indramat FVCA01.2-18K5-3P4-MDA-LP-NNNN-02VRS belongs to the FVCA Frequency Converters series and is engineered by Bosch Rexroth Indramat. It features a Mains Connecting Voltage of 400 V and supports ModBus communication for seamless integration into automated systems. With an Output Power rating of 18.5 kW, this frequency converter delivers precise motor speed control across a wide range of industrial applications, from conveyor systems to centrifugal pumps, providing optimized torque and speed regulation.

This converter operates on a three-phase supply of 3 x 380–480 VAC with a tolerance of –15 %/+10 % and offers a programmable frequency command starting at 0.00 Hz, adjustable via its integrated operator panel. The panel is equipped with an LCD display and a potentiometer for direct parameter tuning, while control commands are accepted through digital and analog inputs, the operating panel, and a serial port. Unique protection features include input and output phase failure detection, overcurrent protection, grounding fault monitoring and a built-in Class C3 EMC filter for compliance with industrial electromagnetic compatibility standards. The LCD backlight automatically shuts off after 80 seconds of inactivity to conserve energy.

Designed for robust operation, the unit must be wall-mounted in a pollution degree 2 environment (EN 50178) with relative humidity below 90 % (non-condensing). It withstands transport temperatures from –25 °C to 70 °C and storage temperatures from –25 °C to 55 °C and complies with low-voltage and EMC directives. The converter uses a 6 kHz pulse width modulation frequency and provides two relay outputs rated at 250 VAC/3 A and 30 VDC/3 A. A continuous rated current of 39 A, along with an external brake chopper and brake resistor, ensures reliable braking and energy dissipation. This combination of precision, protection and compliance makes it an ideal solution for demanding industrial environments, enhancing productivity and operational safety.
