Product Details

STEP POWER Single Phase Power Supplies

The new STEP POWER generation of compact power supply units is particularly suitable for installation distributors and flat control panels thanks to its design. Their high degree of efficiency and the low standby losses make for high power efficiency.

Features and benefits:

Easy mounting on the rail and wall
Maximum energy efficiency through small losses
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

Typical applications:

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.

How to install a DIN Rail Power Supply?

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.

What is a DIN rail power supply?

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.
