PULS PIANO easy-to-use and cost-effective DIN-rail power supply range

Cost-efficient, basic DIN-rail power supplies from 36-480 W with high efficiency, long lifetime and compact size.

PIANO products help customers achieve more with less.

The PIANO product family from PULS, a technology and market leader in DIN-rail power supplies, has been designed for customers who need reliable, easy-to-use and cost-effective DIN rail power supplies. PULS PIANO power supplies are a future-proof and cost-effective investment for systems integrators, these basic power supplies will permanently reduce system costs.

The focus of the PIANO product family is on providing basic functionality without making compromises on PULS’ renowned qualities of efficiency, lifetime, reliability and small size. Additional and more complex features – such as power reserves – have deliberately omitted. This provides a cost-oriented design with no compromises on PULS’ designed-in high quality.

The growing PIANO product family includes more than 17 different DIN rail power supplies offering a range of specifications, such as the input voltage range. This gives customers the opportunity to choose only what is actually required by the specific application.

Regional versions are available to cater for systems to be installed exclusively in Europe, China or India (e.g. in a building) where a wide range input (AC 100-240 V) is not required. PIANO versions marked with “C” at the end of the part number (e.g. PIC240.241C) feature an AC input voltage of only 200-240 V and have a cost saving simpler circuit design with fewer components.

The PIANO Mini-series (PIM), offers users 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.

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 end systems. Due to the basic functionality and smart design of the PIANO power supplies, a lower number of components are required, all of which can be placed on a single printed circuit board. This means lower cost of production and testing which is reflected in the price of the PIANO units. The high efficiency values (90.5 to 95.7% at full load) reduce heat losses, make the power supplies more durable and reduce energy costs for system cooling.

PULS PIANO power supplies are perfectly suited for a wide range of cost sensitive applications, while more demanding applications can be realised with the fully featured DIMENSION products.

Key features of these compact DIN-rail power supplies include:

• 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 which is relevant for the MTBF calculation, the PIANO devices stand out in terms of very high reliability.
• DC-OK signal – and a relay contact for remote monitoring facilitate maintenance and increase availability.
• 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.
• 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 flammability.
