Eaton Inverter Drive, 37kW Power, 72A Current - 197497 DA1-34072FB-B20C


This Eaton DA1 Series inverter drive controls three-phase motors by varying frequency and voltage for industrial applications. It operates from 380 to 480 V supplies and supports speeds from 0 Hz up to 500 Hz, enabling high-frequency operation and four-quadrant control. The unit is intended for vertical panel mounting and incorporates internal brake chopper and DC link components to assist in dynamic braking and motor control within standard electrical switchgear.

Features and Benefits:


• 37 kW power rating provides consistent torque for heavy loads
• 72 A current rating supports high-demand industrial motors
• 500 Hz output frequency enables extended-speed applications
• 97.2% efficiency reduces energy losses during continuous operation
• IP20 protection and vertical mounting simplifies panel integration

Applications


• Suitable for variable-speed conveyors and material-handling systems
• Used with hoists and lift drives requiring four-quadrant control
• Ideal for pump and fan speed regulation in plant systems
• Can be used for extended-speed testing rigs and motor benches

What temperature range can it operate within?


It operates between -10°C and 50°C under normal ambient conditions.

How long can motor cables be when connected?


Maximum permissible motor cable lengths vary by screening and chokes — up to 200 m with a motor choke.

What communications does it support for integration?


It supports Modbus RTU and CANopen and offers optional DeviceNet, EtherNet/IP, PROFIBUS, PROFINET and Modbus-TCP modules.

What braking capability is provided?


It includes a brake chopper with a 12 Ω braking resistor rating and adjustable DC braking torque to 100% with an external resistor.

What environmental or EMC provisions are fitted?


It includes a radio interference suppression filter, additional PCB protection and a DC link choke for EMC performance.
