Configuration PID Easy to perform pressure, flow, temperature close loop control
PLC multiple speed To achieve 16 segment speed running through built in PLC or terminal control
Common Dc bus * Multiple inverters use one DC bus for energy balance.
Auto voltage regulation (AVR) Enable to keep output voltage constant when grid fluctuation
Over load tolerance capability G type model: 150% rated current for 60s, 180% rated current for 2s,
P type Model: 120% rated current for 60s, 150% rated current for 3s.
tall control when over current, over voltage Carry out limiting automation for running current, voltage to prevent over current, over voltage frequently
Fast current limit function minimize the IGBT module broken to protect the inverter, |
