Uninterrupted Power Supplies (UPS) provide critical backup power and surge protection for industrial control systems, automation equipment, and sensitive electronics, ensuring continuous operation during power disturbances or outages. Designed for harsh environments and mission-critical processes, industrial UPS systems stabilize voltage, prevent data loss, and protect equipment from damage caused by sags, spikes, and brownouts. Available in online, line-interactive, and standby configurations, UPS units are essential for maintaining uptime, safety, and productivity in manufacturing, utilities, and process industries.
General industrial power supplies deliver stable, regulated electrical power to automation equipment, instrumentation, control panels, and safety systems in harsh and demanding environments. Designed for reliability and efficiency, these units convert AC to DC voltage with tight tolerances to protect sensitive components from voltage fluctuations, surges, and electrical noise. Available in DIN rail, enclosed, and modular formats, industrial power supplies are essential for ensuring uptime, maintaining system integrity, and supporting mission-critical operations across manufacturing, processing, and utility sectors.
Centro offers a wide range of electrical accessories used to enhance the functionality, safety, and efficiency of electrical systems. These accessories include items such as connectors, terminals, wire management products, fuses, circuit breakers, and protective devices like surge suppressors and grounding equipment.

- Selecting the right pneumatic cylinder starts with defining the four core parameters of your application. Define four core parameters: bore size (force output = pressure × piston area, plus a 25–50% safety factor), stroke length (match to required travel, avoid excess), mounting style (fixed, flange, or pivot to suit your mechanical arrangement), and environment (standard, washdown, or food-grade seals). Speed is controlled by external flow valves, not cylinder selection. For precise positioning, consider a guided or rodless cylinder with position sensing rather than a standard unit.
- A soft starter ramps voltage at startup to limit inrush current and reduce mechanical shock, then steps aside once the motor reaches full speed. Use one when smooth starting is your only requirement. A VFD controls motor speed continuously throughout operation, making it the right choice whenever the process needs variable speed — conveyors, pumps, fans — and it delivers significant energy savings in centrifugal applications. If you only need a gentle start, use a soft starter. If you need speed control at any point during operation, invest in a VFD.
- PLCs are purpose-built for industrial environments — they tolerate heat, vibration, and electrical noise while executing control logic in deterministic millisecond scan cycles. They replace hardwired relay logic with reprogrammable software, making process changes fast and inexpensive. Built-in diagnostics centralize fault visibility and cut troubleshooting time. Modern PLCs integrate with HMIs, SCADA, and enterprise networks via standard protocols, enabling real-time data collection. Modular architecture means the system scales as the application grows.
- Start with the NEMA or IP rating: NEMA 1 for basic indoor use, NEMA 4/4X for washdown and outdoor exposure (4X adds corrosion resistance), NEMA 7/9 for hazardous classified locations. Size the enclosure with 20–30% spare interior space for future additions and adequate heat dissipation. Choose material based on environment — painted steel for standard indoor use, stainless for washdown or chemical exposure, fiberglass for highly corrosive areas. Verify any required certifications (UL, CSA, ATEX) before specifying.
- Solenoid valves are electrically actuated and can be triggered instantly by a PLC or control system, making them essential for automated, repeatable, or high-cycle applications. Manual directional control valves require a person to physically shift the valve and are appropriate for infrequent operations, manual overrides, or applications with no control system. In practice, most automated systems use solenoid valves for normal operation with a manual override built in for setup, maintenance, and emergency use. If the valve must respond to a signal, cycle repeatedly, or operate unattended, solenoid is the correct choice.
