The PIANO product family from PULS has been designed for customers who need reliable, easy-to-use and cost-effective and future-proof DIN rail power supplies.
The focus of the product family is on providing basic functionality without making compromises on 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 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.
Compact housing
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. 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.
The DC-OK signal - and a relay contact for remote monitoring facilitate maintenance and increase availability. The 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.
Two product lines are offered, the PIANO PIM power supplies (PIM36, PIM60, PIM90) with AC input 100 – 240 V and DC output 24V 1.5 A, 2.5 A, 3.8 A and DC 12 V 5 A, output power 36 W, 60 W or 90 W in compact size with low power losses, even in standby (< 0.5 W), push-in or screw terminals, 60 W and 90 W NEC Class 2 versions. The PIANO PIC power supplies (PIC120, PIC240, PIC480) offer AC input 100 – 240 V or 200 – 240 V, DC output 24 V 5 A, 10 A, 20 A and 48 V 10 A, output power 120 W, 240 W or 480 W with high efficiency up to 95.7 %, outstanding reliability (MTBF) up to 1.72 million hours in light-weight, compact and very robust housing.
