B5EED HENF105082R4

Function
Multi channel high-power isolated auxiliary power output
Single phase AC220V input, multi-channel stable voltage isolation output DC24V, ± 15V, 5V, while supplying power to the B3EA sampling board, APBU-44C pulse drive board, ARC093AV1 signal board, and temperature acquisition circuit of this unit; The output power is larger than B5EC, suitable for high-power R8i/R9i heavy-duty inverter units.
Full circuit digital DI/DO fault logic processing
Collect switch values for cabinet door limit, cooling fan, emergency stop, grounding, pre charging contactor, etc; Output passive contacts for fan start stop, fault alarm, and unit lockout relay; The number of channels and load capacity are higher than B5EC, supporting multiple fans and multiple interlocking circuits.
Full monitoring of DC bus pre charging and buffering circuit
Real time monitoring of pre charging status, buffer resistor current, bus surge voltage, and reporting of pre charging abnormalities to the DCU controller in an instant to avoid power on impact breakdown of IGBT power modules; Built in high-power discharge absorption circuit.
Centralized collection and graded reporting of machine faults
Summarize all signals of IGBT overcurrent, driving undervoltage, module overheating, power short circuit, and cooling fault, and transmit them to the DCU main control through the internal bus of the unit; Panel partition LED indicator light, accurately locate the source of the fault.
Strengthen hardware protection
Input side high-power fuse, multi-stage surge absorption, independent channel short-circuit current limiting; Onboard high-power thermistor, directly cuts off all power output when overheating occurs; Strengthen insulation isolation between strong and weak electricity at 2500VAC, suitable for high interference and heavy load conditions in metallurgy and mining.
