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) .
