Protect sensitive and critical electronic equipment—these uninterruptible power supplies (UPS) do not suffer a loss of power when switching from your power source to the UPS during an outage. They also protect against frequency variation and waveform distortion. All have USB and DB9 connections with cords so you can save data and safely shut down an unattended computer during outages. Choose a power output that is equal to or greater than the power your equipment requires.

These units raise or lower current to keep it at a stable level during dips and surges. Choose a power output that is equal to or greater than the power your equipment requires. Determine your required volt-amps by multiplying the amp draw of your equipment by 120V AC.

Install these conditioners in standard 19" wide electronics racks. They raise or lower current to keep it at a stable level during dips and surges. Choose a power output that is equal to or greater than the power your equipment requires. Determine your required volt-amps by multiplying the amp draw of your equipment by 120V AC.

Less than 3" deep, mount these power supplies to a DIN rail in shallow enclosures and control panels, such as those used in building automation systems. They briefly boost power above their maximum operating current to start motors, actuate solenoid valves, and other applications that require a higher starting current than their operating current. All of this means you get a more powerful power supply in a compact size.

These power supplies use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot.

If your power supply exceeds the maximum voltage or load, these power supplies protect both the power supply and the connected equipment. Some also protect against excessive temperatures. All meet the voltage requirements for use in a SELV (separated extra low voltage) circuit.

Rated IP20, these power supplies prevent your fingers from touching internal components and accidentally shocking yourself. They have also passed strict U.S., Canadian, and European Union safety standards.

Maximum output noise is also known as ripple noise. The lower the value, the less interference the power supply creates. For most applications, a value over 100mVpp isn’t a problem. However, when using to power extremely sensitive electronics, such as audio equipment and high- precision measuring and testing equipment, you’ll want an output noise around 5mVpp or less.

Efficiency describes how good a power supply is at converting the AC power it draws from your main electrical supply into DC power. High-efficiency power supplies cost less money to operate and produce less heat, meaning cooler temperatures in your electrical cabinet.

Monitor voltage, current, remaining life, and other maintenance data from your PC, PLC, or by glancing at the digital display. There's no need to inspect these power supplies with multimeters or other test equipment. They also connect to your network, so you can view and analyze data remotely. Like other power supplies, they convert AC to DC voltage to power electronic equipment. Mount these power supplies onto DIN rails, which are commonly found inside industrial cabinets and electrical panels. All have spring-clamp wire terminals for quick connections that hold firmer than screw-style terminals.

Download the free software to view readings, save historical data, and analyze performance over time. Having all of your data in one place means you can troubleshoot and create predictive maintenance plans without needing to walk the floor and open enclosures to perform inspections. Saving historical data reduces maintenance costs because you can better predict when equipment should be replaced. Set alarm conditions, so you're alerted if a particular reading is too high or low. All power supplies are compatible with common Ethernet communication standards—check on them from anywhere without additional measuring equipment or sensors.

All of these power supplies use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. They’re also SEMI F47 compliant, so they meet standards for maintaining output voltage when input voltage dips. This is commonly known as voltage sag immunity.

If you exceed the maximum voltage, temperature, or load, these power supplies protect both the power supply and the connected equipment. They also meet the voltage requirements for use in a PELV (protected extra low voltage) circuit.

Rated IP20, these power supplies prevent your fingers from touching internal components and accidentally shocking yourself. They're UL, C-UL, and TUV certified and CE marked so you know they meet stringent safety standards. With an NEC Class 2 and LPS output, if something fails inside the power supply, these limit the risk of electrical shock. All are rated for use in environments that are not normally hazardous, but where concentrations of combustible gases may occur infrequently.

Maximum output noise is also known as ripple noise. The lower the value, the less interference the power supply creates. For most applications, a value over 100mVpp isn’t a problem. However, when using to power extremely sensitive electronics, such as audio equipment and high-precision measuring and testing equipment, you’ll want an output noise around 5mVpp or less.

Power factor shows how effectively a power supply draws AC power from the main electrical supply. The higher the power factor—up to a maximum score of 1—the lower your operating cost.

Efficiency describes how good a power supply is at converting the AC power it draws from your main electrical supply into DC power. High-efficiency power supplies cost less money to operate and produce less heat, meaning cooler temperatures in your electrical cabinet.

Power supplies with an output peak current briefly boost power above their maximum operating current for starting motors, actuating solenoid valves, and other applications that require a higher starting current than their operating current.
