Sprint Electric E Range Enclosed DC Drives
The Sprint Electric E range provides compact, enclosed DC motor control for industrial applications requiring dependable speed regulation, adjustable acceleration, and straightforward commissioning. Designed around proven Sprint Electric single-phase DC controllers, these enclosed drives combine the controller, protection, and operating controls within a practical panel-mount enclosure.
The range covers DC motor applications from fractional-kilowatt requirements through to 1.8 kW and 12 A, making it suitable for machinery where accurate DC motor speed is needed without the complexity or cost of a larger industrial drive system.
Industrial Motor Warehouse supplies Sprint Electric drives to OEMs, maintenance engineers, machine builders, and industrial users throughout the UK, with technical support and fast UK delivery options.
What Are Sprint Electric Enclosed DC Drives?
Sprint Electric enclosed DC drives are complete drive assemblies that are designed to simplify the installation of a DC motor controller. Instead of installing a standalone controller and separately sourcing the necessary enclosure and basic operating hardware, the E range packages the drive within an aluminum enclosure.
The standard E models are single-quadrant, non-isolated DC drives intended for forward motor operation. The range incorporates controllers from the Sprint Electric 370, 400, 800, and 1200 families. Sprint Electric specifies these enclosed drives for DC motors up to 1.8 kW, with continuous armature-current ratings extending from 3.7 A to 12 A depending on the model.
For applications needing reversing, the corresponding ER variants are available, including the 400ER, 800ER, and 1200ER.
Sprint Electric E Range Models
| Model | Continuous Armature Current | Typical Motor Power | Operation |
|---|---|---|---|
| Sprint Electric 370E | 3.7 A | Up to 0.55 kW | 1Q, Forward |
| Sprint Electric 800E | 8 A | Up to 1.1 kW | 1Q, Forward |
| Sprint Electric 1200E | 12 A | Up to 1.8 kW | 1Q, Forward |
Technical Features of E Range
The E range is engineered around practical industrial control requirements rather than unnecessary complexity. Depending on the model, key features include:
- Single-phase 110-240 V AC supply compatibility
- Single-quadrant forward operation
- Adjustable acceleration and deceleration
- Adjustable minimum and maximum motor speed
- Adjustable motor current limit
- IR compensation for improved armature-voltage-feedback regulation
- Switch-selectable tachogenerator or armature-voltage feedback
- Electronic soft start
- Integrated AC supply fuse
- Graduated speed potentiometer
- Drive run input
- Zero-speed signalling
- Motor overload output
- 0-20 mA and 4-20 mA loop input capability on applicable models
- Torque-control input for basic tension or winding applications
The 400E, 800E, and 1200E models additionally use Sprint Electric’s micro-analogue processor technology in order to provide improved control functionality in a compact analogue-driven platform.
Why Choose an Enclosed DC Drive?
An enclosed drive can reduce panel-building work by integrating the controller and essential operating components into a single assembly. This can be specifically advantageous for replacement projects, machine upgrades, and OEM equipment where installation space and commissioning time are important considerations.
The E range is also well suited to DC motor retrofit applications. If an existing machine still uses a reliable DC motor but its controller has become obsolete or unreliable, replacing the drive rather than the complete motor-and-drive system can provide a more practical upgrade path.
Typical applications include:
- Conveyors and materials handling
- Packaging machinery
- Printing equipment
- Machine tools
- Winding and tension-control applications
- Process machinery
- Small production machines
- OEM machinery
- DC motor replacement and retrofit projects
E Range vs. ER Range
The standard E models are forward-only 1Q drives. Where an application needs electrical reversing, Sprint Electric’s ER versions add an armature reversing module. Sprint Electric specifies the ER range with features including zero-speed interlocked reversing and dynamic braking.
This difference is important when selecting a replacement drive. A motor that must operate in both directions should not simply be matched to a standard E model without assessing the required reversing architecture.
Selecting the Correct Sprint Electric E Drive
Selecting the appropriate controller starts with the DC motor’s armature voltage, continuous armature current, motor power, supply voltage, and feedback arrangement.
As a general selection guide:
- Choose the 370E for lower-current DC motors up to the applicable 3.7 A rating.
- Choose 800E where up to 8 A continuous armature current is required.
- Choose the 1200E where the application needs up to 12 A and approximately 1.8 kW motor power.
- Choose an ER model if controlled electrical reversing is required.
Motor nameplate data should always be checked against the drive’s complete technical specification before ordering.
