MP9-21499K Rev.B EC Capacitor — 3×365 µF, 1000 VAC / 1400 VDC for ABB Converters

The MP9-21499K Rev.B is a high-reliability, three-terminal (3×365 µF) electrolytic capacitor module specifically engineered for demanding industrial drive applications. Designed for integration into ABB’s medium-voltage and high-power converter systems (e.g., ACS880, PCS600, or modular multilevel converters), it delivers robust AC line filtering, DC-link stabilization, and ripple current handling under harsh operating conditions. Key features include: rated voltage of 1000 VAC (RMS, 50/60 Hz) and 1400 VDC (continuous), total capacitance of 1095 µF (3 parallel 365 µF units), low ESR and high ripple current capability, integrated balancing resistors, and UL/ENEC-certified flame-retardant housing. Revision B incorporates improved thermal management, enhanced surge voltage tolerance (≥1600 VDC transient), and updated RoHS-compliant materials per ABB’s latest design specifications.
