Sprint Electric 1220 DC Drives Series
The Sprint Electric 1220 series provides compact, DIN-rail-mounted DC motor control for industrial applications requiring adjustable speed, controlled acceleration, and dependable operation. With a maximum continuous armature current of 12.2 A and a nominal power rating of up to 1.8 kW on a 220-264 V AC, these controllers are suited to small and medium-duty DC motor systems where control-panel space and straightforward installation are important considerations.
Industrial Motor Warehouse supplies Sprint Electric 1220 DC drives for maintenance, equipment upgrades, and new machine builds. The range includes non-isolated, isolated, and regenerative controller options. It allows engineers to select a configuration that matches the motor, electrical installation, and operating requirements.
Technical Overview of the Sprint Electric 1220 Series
The Sprint Electric 1220 range is designed for brushed permanent-magnet and wound-field DC motors, with selected models also supporting universal motors. Its compact DIN-rail mounting format simplifies integration into industrial control cabinets, while accessible adjustments allow engineers to configure motor response without requiring a large, complex drive assembly.
The standard 1220 is a single-quadrant controller with non-isolated electronics. The wider range also includes isolated models and four-quadrant regenerative variants, providing additional options where electrical isolation, reversing, or regenerative operation is required.

Selecting the Appropriate Sprint Electric 1220 DC Drive
Picking up the correct Sprint 1220 DC drive needs more than matching the nominal power of the motor. Engineers should verify armature voltage, continuous current, supply voltage, feedback requirements, and the operating quadrant needed by the application.
The standard 1220 is appropriate for conventional single-direction speed control. Where the application needs isolated control electronics, the 1220i may be a better fit. For applications requiring four-quadrant operation and regenerative capability, the 1220XRi offers a different control configuration. Low-voltage variants are also available for compatible DC motor systems.
DIN Rail DC Motor Controller for Better Space Orientation
A DIN rail DC motor controller can simplify installation in compact control panels, particularly where conventional chassis-mounted equipment would consume valuable enclosure space. The Sprint Electric 1220 uses a narrow mounting profile with plug-on screw terminals and accessible adjustment points, helping reduce installation complexity during machine builds and replacement projects.
The standard 1220 measures approximately 105 x 45 x 120 mm. This compact footprint is useful in equipment cabinets containing contactors, overload protection, terminal blocks, and other motor-control components. Engineers must still allow adequate clearance, wiring access, and ventilation in accordance with the installation instructions from the manufacturer.
The controller’s adjustable parameters also support application-specific commissioning. Minimum and maximum speed settings establish the operating range, while acceleration ramp and current-limit adjustments help configure motor response for the connected load.
What Are 12.2 A and 1.8 kW Ratings?
The 12.2A DC motor controller rating refers to the maximum continuous armature current specified for the 1220 family. The maximum nominal power depends on the incoming AC supply and the corresponding armature-voltage rating.
On a 200-264 V AC supply, the standard 1220 is rated for a typical maximum armature voltage of 180 V and nominal motor power up to 1.8 kW. On a 100-130V AC supply, the corresponding figures are 90V and 0.75 kW.
A 1.8kW DC motor controller should therefore be selected only after checking the nameplate of the motor and the exact drive model. A motor’s power rating alone does not confirm compatibility: armature current, voltage, duty cycle, ambient temperature and starting-load requirements must also be considered.
For applications involving frequent starts, high inertia or sustained operation near rated current, engineers should review the manufacturer’s overload characteristics and thermal requirements before finalising the installation.
Feedback, Speed Regulation, and Commissioning
The Sprint Electric 1220 supports switch-selectable armature-voltage feedback (AVF) or tachogenerator feedback, depending on the configuration and application. These feedback methods affect how the drive responds to changes in motor load and speed demand.
Armature-voltage feedback: AVF provides a practical control method for applications where a tachogenerator is not needed. Adjustable IR compensation helps improve speed regulation as motor load changes, although the achievable regulation depends on the motor and operating conditions.
Tachogenerator feedback: Where a compatible tachogenerator is fitted, tach feedback provides a speed signal that can support more direct speed regulation. Correct feedback polarity, signal scaling, and wiring are essential for stable operation.
At the time of commissioning, set the permitted minimum and maximum speed, acceleration ramp, current limit, and compensation parameters in accordance with the manufacturer’s instructions. Verify motor direction, feedback operation, and protective arrangements before placing the machine into service.
Which One to Choose: 1220, 1220i, and 1220XRi?
The Sprint Electric 1220 range includes multiple control configurations rather than one universal drive for every DC motor operation.
| Model | Control Configuration | Selection Criteria |
|---|---|---|
| 1220 | Non-isolated, single-quadrant | Straightforward single-direction DC motor speed control |
| 1220i | Isolated, single-quadrant | Applications requiring isolated control electronics |
| 1220XRi | Isolated, four-quadrant regenerative | Applications needing reversing and regenerative operating capability |
| LV Variants | Model-dependent low-voltage configurations | Compatible systems using a 30-60 V AC supply |
The isolated 1220i and 1220XRi models offer additional features, including overload protection and push-button reversing. The 1220XRi’s four-quadrant control supports motoring and braking in both directions, subject to the installation and application requirements.
The standard 1220 should not be treated as interchangeable with these models. In particular, single-quadrant control does not provide the same reversing and regenerative capabilities as a four-quadrant drive.
Sprint Electric 1220 Series: Industrial Applications
The 1220 series is suited to equipment using compatible low-to-medium-power brushed DC motors, where applicable speed and compact control hardware are required. Potential applications include:
- Conveyor systems: Adjustable motor speed for compatible light-duty material-handling equipment.
- Packaging machinery: Speed adjustment for auxiliary drives and small machine mechanisms.
- Production equipment: DC motor control in legacy machinery and specialist manufacturing systems.
- Laboratory and test equipment: Controlled motor speed in suitable test rigs and mechanical assemblies.
- Retrofit installations: Replacement of compatible DC controllers without automatically redesigning the entire machine control system.
