Eaton’s PowerXL™ DE1 variable speed starter offers the advantages of both a motor starter and a variable frequency drive in a single device. The DE1 is a compact and easy-to-use device with the ability to change the speed of the motor with the simplicity of a contactor starter. With 14 basic parameters, SmartWire-DT® connectivity and an intuitive configuration module, the DE1 setup and commissioning is easy for any panel builder and MOEM. The DE1 was designed for customers who have concerns of the complexity of a VFD but still require variable frequency and advanced motor protection. Models rated at 480 volts, three-phase, 50/60 Hz are available in sizes ranging from 0.5 to 10 hp. Models rated at 230 volts, single-phase in/ three-phase out, 50/60 Hz are available in sizes ranging from 0.33 to 3 hp.

Why use Eaton PowerXL DE1 series variable speed starter?
Variable speed starters are a new device category that is positioned between conventional motor starters and compact variable frequency drives. This enables them to combine the advantages of three different device categories at the same time: motor starters, soft starters, and variable frequency drives.
Advantages:
- Same ease of use as a motor starter.
- Starting current reduced to rated operational current at full torque from the start.
- Variable motor speed.
- Integrated motor protection.
1 to 1 replacement for contactors.
- 1 to 1 switch from contactor to DE1 without parameter configuration
- Same low wiring complexity
Plus:
- Variable motor speed
- Fixed motor speed at starting current = rated operational current
- No control voltage circuit required (already integrated into DE1).
1 to 1 replacement for motor starters/soft starters.
- 1 to 1 switch from motor starter to DE1 without parameter configuration
- Same low wiring complexity.
Plus:
- Variable motor speed
- Fixed motor speed at starting current = rated operational current
- No control voltage circuit required (already integrated into DE1)
- No separate motor protection required (motor protection integrated into DE1).
1 to 1 replacement for reversing starters/soft starters.
- 1 to 1 switch from reversing starter to DE1 without parameter configuration
- Same low wiring complexity.
Plus:
- Variable motor speed
- Fixed motor speed at starting current = rated operational current
- No control voltage circuit required (already integrated into DE1)
- No separate motor protection required (motor protection integrated into DE1)
- No reversing contactor required (significantly smaller size in terms of width).
Eaton variable frequency drive PowerXL DE1 series – one device, all the advantages.
Ease of use and reliability or variable motor speed and improved energy efficiency? Why not both? Eaton's new device category is closing the gap between conventional motor starters and variable frequency drives. It combines all the benefits in one device: The new PowerXL™ DE1 variable speed starter, now available in version DE11 for machine building applications as well.
Eaton adjustable speed starter PowerXL DE1 series commissioning.
No special knowledge of drives is required for the new DE1 Variable Speed Starter – either for installation or commissioning. The compact Variable Speed Starter is as easy and convenient to use as a conventional motor starter. The device is unpacked and simply wired like a motor starter – that's it. The DE1 Variable Speed Starter is ready to go. It couldn't be easier! In addition, the "out-of-the-box comissioning" reduces the chances of installation faults to a minimum and at the same time it makes installation faster and more cost-efficient!
Saving time and costs.
The new PowerXL DE1 Variable Speed Starter compared to conventional variable frequency drives. The ErP Directive and the increasing levels of automation in machines are pushing the need for variable frequency drives even for simple applications. The DE1 Variable Speed Starter is the ideal solution in all cases where a variable motor speed is required but where a variable frequency drive would be too complex and its expansive functionality would be definitely oversized. It is ideally suited even for fixed speed applications:
- Reduced starting current at full torque
- For constant speed motors, where the required frequency does not correspond to the line frequency (e.g. high speed motors)
- No thermal overload at a high frequency of starts.
