Reliable and service-free buffer module for 24V-systems

The new capacitor buffer module UF40.241, from Puls, is a supplementary device which can bridge voltage dip or loss for regulated DC 24V power supplies. The already successful 20A module is now also available for 40A applications. The UF40.241 can seamlessly bridge failures of the DC voltage supply system and can also extend the hold-up time after loss of the AC mains voltage.Depending on the output current the minimum hold-up time can be 160ms at 40A and goes up to several seconds at lower loads. Especially in regions with poor mains quality, the buffer module can help to uphold the supply voltage so process data can be saved and processes can be completed in a controlled…

Diode redundancy module increases supply reliability

The new, cost-effective diode redundancy module (PIRD20.241) in the PIANO range from manufacturer Puls allows users to build reliable 1+1 or N+1 systems and ensure their operational reliability. The module can be used in either a 2x 10A or 1x 20A configuration, ensures safe decoupling of parallel connected power supplies and is quickly integrated into the system. The input voltage is permitted to be between 9V and 35V and power supplies with both constant current and hiccup overload behaviour are permissible. The wide temperature range of -40°C to +55°C without derating and the narrow width of 39mm permit problem-free use in a wide range of application areas. The PIRD20.241 is the perfect supplementary…

New White Paper: Efficient redundancy for power supplies

Puls engineers worked out a genius MOSFET decoupling solution for redundancy modules. It secures a reliable system availability in case of short-circuit and highest efficiency. The White Paper tells you more about ten criteria that are essential for optimal redundant systems. Standard epitaxial or Schottky diodes can not fulfil all of these criteria - e.g. the need for minimal no-load losses.You will also learn more about the parallel-use mode and the fascinating „hot swapping“ technology that enables you to replace a power supply or a redundancy module while the system is running. Efficient redundancy Reliable system availability in case of short-circuitEfficient redundancy for power supplies Redundancy modules guarantee reliable system availability, even if a…

DIN-RAILway power supplies – a new standard in the railway sector

Proven Industry Technology on Rails For those of you who have sat waiting on a train due to technical problems, you know only too well that more reliable technology on the railway should be the highest priority. A modern train composition is technically highly complex and nothing moves without a reliable power supply. A DIN-RAILway power supply is the answer from Puls for a more robust and reliable DIN-Rail power supply on the railway. Of course, there have been specialised power supplies for the railway for many years. The demands are high and in several areas: Failures cannot occur, even with high mechanical shock in an even broader temperature range. In general, fans…

Efficient redundancy through MOSFET technology

The new and extremely space-saving DIN rail MOSFET redundancy modules from Puls are now available for N+1 and 1+1 redundant systems. Available output voltages include: 12–18V for 2x20A and 2x40A redundancy and 24-56V for 2x20A redundancy.A unique feature of the YR40.245 module adds a Hot-Swappable connector which enables the power supply or redundancy module to be exchanged even during operation. The Puls MOSFET redundancy modules are extremely energy efficient with only 1.7W no-load losses at nominal load and symmetrical current distribution in redundancy mode (max. 2.9W). A special emphasis has also been placed on a very low voltage drop between input and output, which lies between 49mV and 80mV for 1+1 redundancy operation…
