EMI-immune fiber trigger. Onboard re-timing of upstream PWM. Pulse Block on gate fault. Desat and over-temp readback. Redundant trigger channel switchover. Supports 12-pulse, 18-pulse, 24-pulse topologies. Hardware watchdog.

ACS800 MV mining crusher and rolling mill main drive. ACS6000 power plant boiler fan, marine propulsion, rail traction. Multi-pulse rectifier converters with 5SHY IGCT or 5SXE IGBT.

Rectangular PCB, fiber ST or SMA connectors, pulse transformers, gate drive transistors, gold backplane, aluminum mounting brackets, LED for PWR Run Fault Link.

Optical receiver decodes firing word, pulse amplifier charges gate capacitor, pulse transformer couples kV-class pulse to IGCT gate, feedback fiber reports desat over-temp pulse-loss to CPU, watchdog blocks output on lost link.

LOTO MV deck, wait for DC-link discharge, mount on heatsink bracket or cabinet panel, align fiber, torque screws, verify 24 V DC and plus minus 15 V before close.

B107 suffix is fixed HW revision, not interchangeable with B106 or B108 without checking CDR or CM firmware compatibility. Never measure gate output with MV energized. Mixing suffixes in one stack causes Unknown Board ID or Gate Comm Loss.
