PIANO PIC power supplies

PIANO.
Reliable power supplies with basic functionality.

The product family PIANO is designed for users who need reliable, easy-to-use and cost-effective DIN rail power supplies .

The focus of the PIANO product family is on the basic functions without making compromises on PULS’ renowned qualities: efficiency, lifetime, reliability and small size. Additional and more complex features - such as power reserves - were deliberately omitted. This allows a cost-oriented design and high quality at the same time.

The PIANO power supplies are perfectly suited for a wide range of economical applications. More demanding applications can be realised with the fully-featured DIMENSION products.

Reduced system costs

High efficiency values

The PIANO power supplies are a future-proof and cost-effective investment for your system. With these basic power supplies you will permanently reduce your system costs.

The high efficiency values (90.5 to 95.7% at full load) lead to lower heat losses, make the power supplies more durable and reduce your energy costs for cooling your system.

Compact power supply

The modern circuit design of the PIANO DIN rail power supplies fits into a very compact housing. This enables a small width and depth which allows space-savings in your system.

Single-board design

Thanks to the basic functionality and smart design of the PIANO power supplies, a lower number of electronic components is needed. Therefore, all components can be placed on only one printed circuit board. This means lower costs for the production and testing process of the devices, which are reflected in the price of the PIANO units.

Increase system availability

High reliability

PIANO power supplies are characterised by a high MTBF (Mean Time Between Failures) of up to 1.72 million hours. Thanks to the low failure rate in phase B (see diagram), which is relevant for the MTBF calculation, the PIANO devices stand out in terms of a very high reliability.

DC-OK

The DC-OK signal and the relay contact for remote monitoring facilitate maintenance and increase availability (except in the PIM series and PIC120.242C ) .

Don't worry about safety issues

High immunity

The PIANO power supplies can withstand powerful input transients up to 230% of the nominal input voltage. This electrical robustness is assured throughout the entire load range.

Robust housing

The high-grade polycarbonate housing enables a light-weight design. Polycarbonate is a very durable material which has passed all stress tests (shock, vibration, temperature) without any problems. All units also comply with the V0 class of inflammability.

Stay flexible

14+ different devices

The growing PIANO product family includes more than 14 different DIN rail power supplies. The devices differ in certain details, like the input voltage range. This gives you the opportunity to choose only what you really need.

Regional versions

If you operate your systems exclusively in Europe, China or India (e.g. in a building) you do not need a wide range input (AC 100-240V). So you can choose the PIANO versions marked with "C" at the end of the order number (e.g. PIC240.241C ). These units feature an AC input voltage of only 200-240V and have a simpler circuit design and less components. This will save you costs.

Push-in or screw terminals

With the PIANO Mini-series (PIM), users have the choice between push-in and screw terminals. Push-in terminals allow time-saving installation without tools and are very robust against shock and vibration.
