High reliability. Very attractive price.
With the new PIANO series, PULS-quality DIN-rail power supplies are now available for even the most cost oriented user. Through a fresh and innovative approach, the intrinsic properties of a PULS power supply (high reliability and long service lifetime) have now been introduced into a product that also has significant price advantages. PIANO prices are 20 to 40% below previous model prices.
Despite our low cost requirements, an MTBF of more than 1.4 million hours and efficiencies of 90.5 to 95.2% have been achieved. This innovation was made possible by a clever single-board design, cost-saving polycarbonate housing and a design team that was focused on an intelligent design for manufacturability.

hours service life.
To ensure that your application continues to function properly, PIANO includes a DC-OK signal, an operational temperature range of up to +55°C (without derating) and large input and output terminals all within a light and compact housing. The 24V/10A unit, with a width of only 49mm, is the same size as the smallest “new to market” high-end products from other vendors.
The efficiencies of the PIANO series are between 90.5 and 95.2% at 230V and thus very high, especially for devices in this price range.
All users can appreciate the advantages and savings of the unit’s high efficiency and low heat generation which in turn makes the high reliability, long service lifetime and compact design all possible.
The stylish housing of the PIANO series is made of a high quality polycarbonate. This material is characterized by its high strength, impact toughness and hardness, which is why this material is most commonly used in sophisticated products like SLR cameras, smartphones and laptops. The design has been extensively and rigorously tested and passed with significant safety margins.
The sleek housing promotes a striking first impression and its quick installation and resistance to corrosion upholds this sentiment. The light weight design is especially advantageous against high mechanical shock and vibrational stresses.
Best-in-class service lifetime
The Service lifetime of the new PIANO-series is remarkably high when compared to similar products on the market. The outstanding service lifetime was achieved by the highly efficient and sophisticated thermal design of the PIANO but also by choosing to use high end components with long service lifetimes (e.g. electrolytic capacitors).
High reliability | MTBF
A high MTBF value expresses the outstanding reliability of the PIANO series. These high reliability figures are attributed to the unit’s low internal temperatures (thermal design) as well as an intelligent design that uses fewer and unstressed components.

Small size. light weight
With a width of only 49mm, the 24V / 10A unit is small but definitely worth noticing. It is the same size as the smallest and “newest to market” high-end products from other vendors. The 120W devices weigh between 350-370g and the 240W units weigh a maximum of 550g.
Space on the DIN-rail is always precious and therefore a smaller power supply can provide a solution. The low weight reduces stress on the DIN-rail and makes the device sturdy, even at high shock and vibration levels.
The single board concept in conjunction with the polycarbonate housing leads to easier manufacturing and testing procedures while increasing the process reliability.
Lower production costs means that the savings are passed on to the customer.
Easy to use
Conductor cross-sections of up to 6 mm² for solid wires and 4 mm² for stranded wires are easily assembled. The large screws promote easy and comfortable wire fixation which can prevent unsafe connections.
Fast, easy and safe wiring.
DC-OK signal output with relay
All PIANO power supplies have a DC-OK LED. They also have the ability to report the DC-OK signal via a floating relay contact with the exception of a further cost-reduced version. A mechanical relay was used due to its ease of use when compared to a semiconductor relay.
Increased system reliability is achieved through a simple monitoring function.
