DC Power Supplies for Electromagnets
DC power supplies are available in four types with various levels of output to control electromagnetic forces with precision. They are used with compatible electromagnets where the application requires constant output, reversing output, variable output, or both variable and reversing control.
NEMA 12-J.I.C. oil tight, industrial type enclosures are standard. Pilot lights, control switches, and other control options are available depending on the application requirements.

DC Power Supply Options
Use the sections below to compare fixed output, reversing output, variable output, and variable plus reversing output DC power supplies. Each chart has been converted from an image into a real HTML table for easier filtering and reading.
Fixed Output DC Power Supply
Provides rectified voltage for constant power. This is common for all other power supply styles.
| Part No. |
Input (VAC) |
Output (VDC) |
Watts | H x W x D |
|---|---|---|---|---|
| E010-4020 | 115/230 | 12/24 | 200 | 12" x 10" x 5" |
| E010-4025 | 115/230 | 90 | 250 | 12" x 10" x 5" |
Reversing Output DC Power Supply
Provides the feature of inducing a reversing current to help eliminate residual induction for release of small parts. Designed to be controlled by PLC.
| Part No. |
Input (VAC) |
Output (VDC) |
Watts | H x W x D |
|---|---|---|---|---|
| E010-4120 | 115/230 | 12/24 | 200 | 12" x 10" x 5" |
| E010-4125 | 115/230 | 90 | 250 | 12" x 10" x 5" |
Variable Output DC Power Supply
Provides adjustable voltage from zero to full rated voltage. Fine tuning capability makes this style useful for lifting single thin gauge parts from stacks without lifting two or more parts.
| Part No. |
Input (VAC) |
Output (VDC) |
Watts | H x W x D |
|---|---|---|---|---|
| E010-4220 | 115/230 | 0-12/24 | 200 | 12" x 10" x 5" |
| E010-4225 | 115/230 | 0-90 | 250 | 12" x 10" x 5" |
Variable and Reversing Output DC Power Supply
Provides two features for maximum operation control and application flexibility. This style can help when the system needs both adjustable holding force and reversing current for part release.
| Part No. |
Input (VAC) |
Output (VDC) |
Watts | H x W x D |
|---|---|---|---|---|
| E010-4320 | 115/230 | 0-12/24 | 200 | 16" x 10" x 5" |
| E010-4325 | 115/230 | 0-90 | 250 | 16" x 10" x 5" |
Sourcing Note
DC power supply selection should be based on the electromagnet voltage, wattage, required control style, part release requirements, PLC integration needs, and enclosure requirements. Review the complete application before selecting a power supply based only on voltage output.
Frequently Asked Questions
What does a DC power supply do for an electromagnet?
A DC power supply provides the direct current needed to energize the electromagnet. The selected power supply affects how the magnet is turned on, controlled, adjusted, and released.
What is the difference between fixed and variable output?
Fixed output provides constant rectified voltage. Variable output allows the operator or control system to adjust the output from zero to full rated voltage for finer control of magnetic force.
Why would I need reversing output?
Reversing output can help reduce residual magnetism and improve release of small parts after the electromagnet is turned off.
When should I use variable and reversing output together?
Variable and reversing output is useful when the application needs both adjustable holding force and improved part release. This gives the most control and flexibility among the listed power supply types.
Can Storch help match a power supply to an electromagnet?
Yes. Electromagnet voltage, wattage, duty cycle, control method, release requirements, and application details should be reviewed before final selection.
