Product Description:
The 8I64T401100.00X-1 Inverter is part of the ACOPOSinverter X64 series designed for asynchronous motor control in industrial automation. It is developed by Bosch Indramat for industrial automation tasks. It functions as a variable frequency drive for three-phase AC power applications.
The supply voltage range of the 8I64T401100.00X-1 inverter is from 380 V to 500 V AC at 50/60 Hz. At 380 V input, the current draw reaches 37.2 A during standard operation. At 500 V input, the current draw decreases to 28.4 A efficiently. The inverter delivers 25.0 kVA apparent power when operating at a 500 V input level. The maximum inrush current supported is 97 A during initial power-up conditions. The switching frequency is user-adjustable between 2 kHz and 16 kHz. The default factory setting for switching frequency is configured at 4 kHz. The 8I64T401100.00X-1 inverter delivers a nominal output current of 27.7 A under rated load operation. A short-term transient current of 41.6 A is supported for 60 seconds. This equals 150 percent of the nominal output current for temporary load spikes. The heat dissipation during operation is measured at 397 watts of power loss. The terminals support cable sizes ranging from 10 mm² to 25 mm². Wire gauges between AWG 8 and AWG 4 are compatible with terminal connections.
The terminal screws of 8I64T401100.00X-1 inverter require a torque of 4.5 Nm for proper fastening. The inverter measures 245 mm in width and 329.5 mm in height. The depth dimension of the housing is 192 mm, and the weight totals 9 kilograms. A built-in EMC filter is included to suppress electromagnetic interference during use. The EMC filter can be disconnected for installations in IT networks if required. The cooling airflow required is 168 cubic meters per hour or 99 CFM. The protection for the input circuit requires a 50 A Class J fuse.
Frequently Asked Questions about 8I64T401100.000-1:
Q: How does 8I64T401100.00X-1 inverter optimize input current efficiency?
A: The 8I64T401100.00X-1 inverter reduces input current from 37.2 A at 380 V to 28.4 A at 500 V. This minimizes cable heating and improves power distribution efficiency.
Q: Why does 8I64T401100.00X-1 inverter offer adjustable switching frequency?
A: The 8I64T401100.00X-1 inverter allows 2–16 kHz switching to balance acoustic noise and motor heating. Lower frequencies reduce EMI, while higher values improve current smoothness.
Q: What benefits come from 8I64T401100.00X-1 inverter’s short-term overload capability?
A: The 8I64T401100.00X-1 inverter supports 150% output current for 60 seconds. This provides headroom for acceleration surges or intermittent torque spikes in motion profiles.
Q: How does 8I64T401100.00X-1 inverter manage electromagnetic interference?
A: The 8I64T401100.00X-1 inverter includes a built-in EMC filter to suppress conducted noise. The filter is disconnectable to accommodate IT-network compatibility or insulation monitoring.
Q: Why is 4.5 Nm terminal torque specified for 8I64T401100.00X-1 inverter?
A: The 8I64T401100.00X-1 inverter uses a 4.5 Nm torque setting to ensure reliable electrical contact. Under-tightening risks heat buildup, while overtightening can damage terminals.
