IMO Precision Controls DIN Rail Power Supplies

IMO Precision Controls DIN Rail Power Supplies

Choose Reliable DC Power Without Oversizing Your Control Panel

Match the incoming supply, required DC voltage, continuous load and peak demand to an IMO power supply from 10W to 480W.

⚡ What is an IMO power supply for?

An IMO DIN rail power supply creates the stable DC power that a control panel needs from the available AC or DC input. It mounts directly on the DIN rail and supplies sensitive automation equipment with consistent voltage, helping prevent unreliable operation caused by an undersized or poorly matched power source. The right model is selected according to the panel's input power, required output voltage, continuous load and short-term peak demand.

Size a DIN Rail Power Supply in 4 Checks

Work from the load back to the incoming power. This prevents voltage mismatch, nuisance shutdowns, or unnecessary cabinet space.

1️⃣

Confirm the input

Identify phase count and voltage first. Standard single-phase models accept universal low-voltage input; WPS accepts 180–550VAC; selected LPS models accept 340–550VAC three-phase input.

2️⃣

Match DC voltage

Use the exact voltage required by the loads. Available models include 5VDC, 12VDC, 24VDC and 48VDC outputs; 24VDC is the broadest selection.

3️⃣

Add continuous load

Add the current draw of every device powered at the same time. Convert amps to watts with W = V × A.

4️⃣

Allow operating margin

Target about 20–25% reserve capacity for normal expansion and load variation. Check inrush separately; HPS can supply 150% rated power for 3 seconds.

Compare IMO Power Supply Series

Start with the series that solves the hardest requirement, then select the voltage and wattage.

HPS • PEAK PERFORMANCE

For inrush and short peak loads

Choose HPS when motors, actuators or capacitive loads create a brief demand above the normal operating load.

  • 120W, 240W and 480W models
  • 12VDC, 24VDC, and 48VDC options
  • 150% peak power for 3 seconds
  • Single-phase universal input

LPS • BROADEST RANGE

For general machine control

Choose LPS for common panel loads and the widest selection of output voltage, wattage and input phase.

  • 10W through 480W on this page
  • 12VDC, 24VDC, and 48VDC models
  • Single- and three-phase options
  • Plastic or metal housing by rating

SPS • MODULAR

For compact modular enclosures

Choose SPS for narrow DIN rail layouts, building automation and control circuits that benefit from a modular plastic housing.

  • 12W through 150W
  • 5VDC, 12VDC, and 24VDC options
  • Class II isolation
  • IP20 modular design

WPS • WIDE INPUT

For high-voltage input systems

Choose WPS when the available power is 180–550VAC or 254–780VDC and the control circuit requires 24VDC.

  • 60W, 120W and 240W models
  • 24VDC output

IMO Power Supply Model Selector

Use the output current as the maximum connected load at the rated voltage. Open any model to review its complete specifications before ordering.

🧮 Quick Sizing Example

Add the 24VDC loads

PLC: 0.7A
HMI: 0.8A
Sensors and relays: 1.5A
Total: 3.0A

Add 25% reserve

3.0A + 25% (0.75A) = 3.75A
Using W = V × A, the required capacity is:
24V × 3.75A = 90W

Select the next rating

A 120W, 24VDC, 5A model provides the required continuous output and leaves room for normal expansion.

🏭 Typical Industrial Automation Uses

Machine ControlPower PLCs, I/O, relays and operator interfaces from one regulated DC source.
Process SystemsSupply transmitters, controllers and panel instruments that require stable low-voltage DC.
Building AutomationUse compact SPS models for controllers, sensors and auxiliary circuits in modular enclosures.
High-Voltage PanelsUse WPS wide-input models where 180–550VAC power is available and the controls require 24VDC.

✅ Pre-Order Checklist

☐ Input voltage and phase match the panel

☐ Output voltage matches every connected load

☐ Rated current exceeds simultaneous load

☐ Inrush or peak demand has been checked

☐ Temperature derating is included

☐ DIN rail space and ventilation are available

☐ Branch protection and wire size are correct

☐ Required approvals are verified for the application

Final selection and installation should follow the product datasheet, applicable electrical codes and the requirements of the connected equipment.

IMO Power Supply FAQ

Which IMO power supply is best for a PLC panel?

For a typical 24VDC PLC panel, add the current of the PLC, HMI, I/O, sensors and relays, add operating margin, then choose an LPS or SPS model with adequate current. Use HPS if the load has a short high-current peak.

When should I use an HPS model?

Use HPS when the load requires short-duration power above its steady-state demand. HPS models provide up to 150% of rated wattage for 3 seconds, subject to the model specifications.

What is the difference between LPS and WPS?

LPS covers more output voltages, wattages and phase configurations. WPS is the direct choice for 24VDC loads supplied from a wide 180–550VAC or 254–780VDC input range.

How much spare power capacity should I allow?

A practical starting point is 20–25% above the calculated continuous load. Increase the margin when future expansion, ambient temperature, voltage drop or repetitive inrush affects the design.
