Product Description:

The ACOPOS Inverter 8I74T400150.010-18I6 is manufactured by B & R Automation with the aim of providing precise control of motors in industries. This inverter has a mains Input of 3x 380-500VAC±-15%+10%, so it can be used with various Regional power supplies.

For system safety, the 8I74T400150.010-18I6 inverter accommodates a maximum assumed short-circuit current of 5 kA to provide a safe response to unplanned faults. This inverter gets extensive flexibility of control in terms of output frequency range of 0 – 599Hz, to operate in both low-speed accuracy as well as high-speed operations. The relay response time for this inverter is limited to 2 ms to allow for quick transitions and signal execution within the control system. This inverter has a built-in EMC filter, which limits conducted emissions and electromagnetic noise in control cabinets. This also satisfies industrial EMC standards and reduces interference hazards for adjacent equipment. This inverter has a 1.5 kW (2 HP) motor power rating, which is excellent for compact-scale machines as well as mid-range automation networks. The protection functions for this inverter include Class 10 Motor Overload Protection, which protects it against overheating and mechanical stress during overloads.

The input frequency range of 50 to 60 Hz ±5% provides this inverter with a stable operation under typical power supply conditions and accommodates small deviations without any performance loss. The output current of this inverter supports 4.1 A max output with regularity to provide efficient operation with sustained load changes. A rated apparent power of 4.2 kVA at 500 VAC allows efficient access to available power levels when this inverter is operating. This inverter’s maximum inrush current of 10 A prevents input power line disturbance during startup and minimizes the effect on upstream breakers or fuses.
