PULS: PIANO PIM Series – Power Supply Solutions
July 8, 2026
Compact PIANO Mini (PIM) Creates More Space in Your Systems or Machines & Allows for Flexible Planning
The PULS PIANO product family is designed for users who need reliable, easy-to-use, and cost-effective DIN rail power supplies. The most important characteristic of all PIANO devices is their focus on the core features of a power supply: efficiency, lifetime, reliability and 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.
The compact PIANO Mini (PIM) power supplies are available with 36 W, 60 W or 90 W. These power supplies create more space in your systems or machines and allow you a flexible planning. Furthermore, you can choose between push-in and screw terminals for the PIM60 (60 W) and PIM90 (90 W).

Your Benefits – Simplicity without Compromises
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.
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.
Secure Your System: Redundancy Module with Basic Functionality
Secure your system with the PIRD20.241. This redundancy module with basic functionality perfectly complements our PIANO DIN rail power supplies. It allows you to build cost-effective 1+1 redundant power supply systems.
