Power Conversion & Protection

Shop products used to convert, regulate, condition and protect electrical power in industrial, commercial and control-system applications. Available product families include transformers, industrial power supplies, uninterruptible power supplies, power conditioners, surge protective devices and related accessories.

Browse by product type to compare products from multiple manufacturers. Selection factors may include input and output voltage, phase, frequency, power rating, output current, mounting method, enclosure type and the type of power disturbance or load being addressed.

Selecting Power Conversion and Protection Equipment

Electrical equipment may require voltage conversion, regulated DC power, temporary battery backup or protection from disturbances on the incoming power line. The correct solution depends on the source power, connected load, operating environment and the specific electrical problem that must be addressed.

Transformers change voltage levels and can provide electrical isolation. Industrial power supplies convert incoming AC power into regulated DC power for control devices and automation equipment. UPS systems provide temporary backup during power interruptions, while power conditioners and surge protective devices address different types of voltage disturbances.

Major Product Families

• Transformers: Convert voltage, provide isolation or adapt electrical power for control, distribution and equipment loads.
• Industrial power supplies: Provide regulated DC output for PLCs, sensors, relays, communication equipment and control systems.
• Uninterruptible power supplies: Support connected equipment temporarily during power interruptions and selected voltage disturbances.
• Power conditioners: Regulate or condition incoming voltage for equipment sensitive to power-quality problems.
• Surge protective devices: Help limit transient overvoltage reaching connected equipment.

Important Selection Factors
