Product Description:

The 8I76T400037.0P-000 is a variable-speed inverter delivered by B&R Automation within the 8I7 ACOPOS Inverters series. Designed for cabinet installation, the unit regulates the torque and speed of small three-phase motors used in conveyors, pumps, and positioning axes across factory cells. It links field devices to higher-level controls while supporting deterministic Powerlink communication, making it suitable for compact industrial motion applications.

It provides a continuous motor power of 0.37 kW, matched to an apparent power capability of 1.2 kVA when fed from a 380 VAC network. Under nominal load, the output stage delivers 1.5 A while the mains side draws 1.8 A, and during energization the line sees an inrush peak of 10 A. For short overload windows of up to 60 s, the drive can supply higher transient phase current, and a minimum brake resistor of 80 Ω may be connected to dissipate regenerative energy. The pulse-width-modulated bridge operates at a 4 kHz clock frequency so acoustic noise and current ripple remain low. A Type 3 Powerlink interface is embedded for real-time bus coupling, and the factory-installed EMC filter limits conducted emissions without external components.

Mechanically, the inverter occupies 45 mm in width, 232 mm in depth, and 325 mm in height, with a mass of 2.5 kg that supports DIN-rail mounting. The housing carries an IP20 degree of protection, so it must be installed inside a closed panel while still providing finger-safe device surfaces. Continuous control losses are held to 27 W, allowing natural convection to maintain device temperature without forced cooling hardware. The inverter can deliver 2.3 A during brief overload periods, which supports demanding acceleration and deceleration events within its rated operating range.
