Reviews around cirtuit protection (5.00 of 5)

  • so I got my hands on it to repair (at least there's full schematic available online) and discovered that the power stage is a FAIL. 5 pairs of IRFP240 and IRFP9240 without ANY kind active power distribution balancing, no internal short-cirtuit protection, no per-mosfet thermal monitoring

Reviews around circuit protection (5.00 of 5)

  • Since there is no overload or short-circuit protection for power stage input this means one MOSFET failure leads to full chain-reaction which destroys every MOSFET in that channel, every passive balance resistor, feedback resistors, gate resistors and gate driver zener diodes

Reviews around engineer wonder (5.00 of 5)

  • I spend a whole week analyzing and repairing this piece of "engineering wonder" when it could be prevented simply by adding an active fuse to MOSFET power input
