High‑Efficiency Performance for Demanding Environments
These power supplies are built to run efficiently under load, keeping output steady even when temperatures or electrical conditions shift. Their efficiency helps cut down on excess energy use and heat, which in turn eases the strain on downstream equipment and supports smooth system operation.
Global Certifications for Simplified Compliance
Many models meet worldwide standards such as UL, CE and CSA, making it easier to support global machine builds without redesign. This level of standardization can reduce engineering effort and help speed deployment for multinational OEMs.
Integrated Diagnostics & Status Monitoring
Select models include LED indicators, output status and diagnostic functions that can help pinpoint power issues more quickly. These tools give maintenance teams clearer insight into system conditions and can streamline troubleshooting.
Flexible Mounting & Scalable Configurations
DIN‑rail, panel‑mount and on‑machine options give you flexibility across different panel types and machine layouts. This range of installation choices supports both centralized and distributed system designs.
Protection Against Voltage Disturbances
Voltage‑sag protectors help maintain operation during dips and brief outages. Sag events are a common source of industrial interruptions, and added protection can help reduce nuisance resets and system faults.

Control Circuit Transformers
Control circuit transformers provide isolated, stable voltage for control logic, relays and signaling devices. They’re built for industrial use and help maintain consistent operation of low‑voltage control circuits when line‑power conditions vary. With multiple kVA ratings available, they’re a practical choice for machine builders who need code‑compliant control power in a range of applications.
On‑machine power supplies mount directly on equipment, helping reduce panel space and simplify wiring in decentralized architectures. Their sealed construction is built to withstand dust, moisture and vibration, making them a practical fit for harsher operating areas. This approach can shorten installation time, streamline cable routing and support modular machine design.
Switched mode power supplies (SMPS) offer high energy efficiency, compact footprints, and steady DC output across changing load conditions. With wide input ranges, overload protection, and optional redundancy, they support control systems that need flexibility and more dependable performance. SMPS units are a core component for PLCs, sensors and other electronic control devices.
Voltage sag protectors help safeguard equipment during dips, brownouts and brief grid disturbances. By maintaining more stable output power, they can help reduce controller resets, motor faults and other interruptions. They’re a practical fit for facilities with variable utility conditions or equipment that creates high‑impact load cycles.
Our innovative safety products and solutions improve the functional operation of your machinery while helping to increase personnel safety, efficiency and productivity.
How do I choose the right power supply for my control system?
Choosing a power supply depends on load requirements, redundancy needs, mounting location, input voltage and the environmental conditions around the equipment. Switched‑mode supplies work well for compact, efficient DC power, while on‑machine models support more distributed architectures.
When should I use a voltage sag protector?
Voltage sag protectors are useful in environments with grid instability, motor‑starting dips or intermittent outages. These events can reset controllers, interrupt processes or affect sensitive electronics. Sag protectors help maintain more stable output during short‑duration disturbances, giving systems a better chance to ride-through events that last from milliseconds to a few seconds.
What’s the benefit of using switched mode power supplies instead of linear power supplies?
Switched‑mode power supplies (SMPS) offer higher efficiency, generate less heat and take up less space than linear supplies. They’re well‑suited for automation components that need stable DC voltage under varying load conditions. Their wide input range also supports global voltage requirements and can simplify panel design.
Can I mount power supplies outside the control panel?
Yes, on‑machine power supplies are designed for decentralized mounting and use sealed housings with environmental ratings suited for exposed locations. Their tolerance for shock and vibration makes them a practical option outside the enclosure. This approach can reduce enclosure size, simplify wiring and support modular layouts in distributed applications.
How do I size a control circuit transformer?
Sizing depends on the total VA load of the connected devices, their inrush current demands, and any applicable regulatory requirements. It’s important to choose a transformer with enough headroom to handle surge loads from relays, solenoids and contactors. You can reference the control‑transformer portfolio for available ratings and wiring configurations.
