Space-Saving DIN-Rail Mount Surge Suppressors

Protect equipment in tight spaces such as crowded control panels. These surge suppressors are more compact than standard size models. They have a built-in mechanical fault indicator that shows at a glance when the suppressor needs replacement. Screw-terminal connections allow you to tighten wiring with a tool for a more secure hold that won’t loosen with vibration.

Low-Profile DIN-Rail-Mount Power Supplies

Power Supply on DIN

Rail

Less than 2 _1/2" 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 Peak-to-Peak—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 @ Voltage—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.

Voltage-Monitoring Relays

Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage. These relays continuously monitor your AC or DC power supply and trip when the voltage is outside a set range. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

Monitoring Relays

With Spring-Clamp Terminals—Relays with spring-clamp terminals connect and disconnect to wire without screws. Because there’s no screw, these connections are less likely to loosen over time, even in high-vibration environments.

Knob Adjustment—Relays with knob adjustments have knobs right on the front where you can set your trip voltage. You can see that they're wired correctly and when they're actuated based on the LED indicators. If you want to mount these relays to a surface instead of DIN rail, they have mounting holes.

AS-Interface-Network DIN-Rail-Mount Power Supplies

Send both electrical and data signals to equipment on AS-interface networks. These power supplies briefly boost power to 150% of their maximum operating current for starting motors, actuating 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.

Mount these power supplies to a DIN rail in your industrial cabinet or electrical panel. To monitor sudden voltage drops, wire them to a panel light or alarm, or connect them to a PLC (Programmable Logic Controller).

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, they protect both the power supply and the connected equipment. These power supplies also meet the voltage requirements for use in a SELV (separated extra low voltage) circuit.

Rated IP20, they prevent your fingers from touching internal components and accidentally shocking yourself. They're also UL and C-UL listed, UL recognized, and CE marked so you know they meet stringent safety standards.

Power Factor @ Voltage—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.

Status-Indicating DIN-Rail-Mount Power Supplies

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.

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 and C-UL Listed, TUV Rheinland 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.

Output Peak Current—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.
