Product Description:
The 8I84T400220.010-1 Frequency Inverter is a compact and reliable drive solution for industrial motor control applications. The model supports 3 phase mains input with a broad voltage range. The inverter ensures consistent operation, thermal efficiency and stable torque output under demanding conditions.
This 8I84T400220.010-1 frequency inverter from B & R Automation operates with a 3 phase input of 380 VAC (− 15 %) to 480 VAC (+ 10 %). The frequency range is 50 to 60 Hz with a ± 5 % tolerance. The maximum input current with an optional mains choke at 230 VAC is 14.6 A. The Mains current values vary with input conditions: 5 A at 400 VAC, 8.2 A at 380 VAC and 7.1 A at 480 VAC. The inverter handles a maximum assumed short circuit current of 5 kA at the connection point. It includes an integrated EMC filter for improved noise immunity. The power dissipation of this frequency inverter at nominal load and clock frequency is 114 W. The device supports motor connection with no derating up to + 50 °C maintaining performance at high ambient temperatures.
The output frequency range of the 8I84T400220.010-1 frequency inverter is from 0.5 Hz to 599 Hz. The nominal clock frequency is 4 kHz with a minimum of 1 kHz and a maximum of 16 kHz. The frequency inverter is capable of delivering high short term overload torque. It supplies up to 170 % of the motor’s rated torque for a duration of 60 seconds and peaks at 220 % for up to 2 seconds. This capability ensures reliable operation during demanding load conditions such as acceleration, impact loading or momentary mechanical binding.
