Product Introduction
The CONVERTEAM MVC3003-4030A provides switched-mode auxiliary power in ALSPA MV3000 DELTA medium-voltage drives, pulling from the DC link to feed control electronics, gate drivers, and fans even during brief supply dips.
It offers enhanced overvoltage handling for larger transistor bridges (MVDL800/MVDL1000), with a configurable timed trip window (up to 7.5 s) at 1188 V DC before instantaneous cutoff at 1262 V DC — useful in wind converters or industrial drives with grid transients or regenerative loads. Install only in position 1 as master; slave roles use -4025 variants. Cross-check DC link ratings and daughter board links against your transistor module type before swap — higher transient withstand suits upgraded bridges but demands correct config.
