Phoenix Contact STEP-PS/48AC/24DC/0.5 Switch Mode DIN Rail Power Supply, 43 → 52 V ac / 60 → 80V dc ac,

The single-phase STEP POWER generation of compact power supply units from Phoenix Contact have a high degree of efficiency and the low standby losses make for high power efficiency. The PSU’s are available with 24 V DC output voltage in various performance classes and overall widths as well as special voltages 5, 12, 15, and 48 V DC.

These PSU's (Power supply units) have been designed more specifically for building automation, however, are not limited to explicitly that use. Low idling and maximum efficiency help to achieve higher energy efficiency. Not to mention, these power supplies have a DIN rail notch took out of the housing to allow you effortless install, on a DIN rail. DIN Rail power supply's are great for cable management, having everything in a single cabinet for consistent maintenance and ease of use.

• Easy mounting by snapping on the DIN rail or screwing onto a level surface
• Maximum energy efficiency through small losses
• Reliable power supply thanks to high MTBF (mean time between failures) of more than 500,000 hours and U/I characteristic curve
• Fast commissioning with LED function monitoring
• High operational safety by long power failure under full load
• Worldwide use by wide-range intake and international approval package
• Wide temperature range from -25 ° C to +70 ° C
• Parallel switched to increase performance and redundancy
• Outdoor installation possible
• Energy savings thanks to maximum energy efficiency and incredibly low idling losses

The design of the PSUs makes them suitable for installation distributors and flat control panels. More specifically, these STEP POWER PSU's have been designed to cater for building automation applications.

DIN rail power supplies typically feature an easy install. With the ability to mount it onto a compatible DIN rail, all you usually have to do is slide it onto one. These STEP DIN rail power supply's support NS 35 (EN 60715) rails. Once you've slid your power supply onto your rail, it is then a case of connecting your cables into the relevant inputs and outputs. Wires must be stripped 6.5mm before inserting into the terminal blocks. The terminal blocks are an effortless screw connection, making your install simple.

Effectively, a DIN rail power supply is a power supply, that is designed to be put on a DIN rail. These power supplies cater to the industrial world, rather than consumer electronics. They feature different connection methods such as terminal block connections rather than your typical 3-pin socket power. DIN Rail PSU's are designed to sit inside cabinets and work hand-in-hand with providing higher efficiency for industrial applications.

UL/C-UL Recognised (UL 60950), UL/C-UL Listed (UL 508) approved

This single-phase compact power supply from Phoenix Contact provides a reliable 24V DC power source for your equipment. It's built to compact dimensions, with a width of just 18mm, so saves space in your cabinet. An operating temperature range of -25°C to +70°C makes it suitable for use in harsh indoor environments, and you can also install it outdoors. A mean time between failures of 500,000h means it will offer you a long service life.
This power supply has been designed for use in building automation applications such as lighting control systems and heating, ventilation and air-conditioning equipment. It can also be found in other industrial applications, such as in urban infrastructure.

• Efficiency of more than 81% and very low idling losses save energy
• Ripple and noise of 30mV Pk-Pk to minimise wastage and heat dissipation in the cabinet
• Parallel switched to increase performance and redundancy
• LED function monitoring makes it easy to check the unit's status, even in low light environments
• Line regulation of ±0.1% and load regulation of ±1% means it will deliver a stable supply despite any fluctuations in the input voltage
