PULS Power has introduced new models in its PIANO series of DIN-Rail AC/DC converters. The PIANO-PIM family has been designed for use in industrial applications which only require a basic power supply, avoiding the need for users to pay for unnecessary control and communication facilities, says the company. The new series offers a 100-240V AC range input; 24V DC output units are available in three versions: PIM36 (36W), PIM60 (60W) and PIM90 (90W). With these additions to its range PULS now provides users with a complete and cost-oriented product family with outputs from 30W to 480W. At ambient temperatures between -10 °C and +55 °C, the devices work at full power without derating. The PIM90 is also available as an NEC Class 2 version for the US market.
The PULS PIANO-PIM single PCB design uses a reduced number of components, lowering cost, and is said to simplify manufacture and improve reliability. PULS claims that the PIM90 is currently the smallest 90W DIN-Rail power supply on the market. The high-efficiency synchronous rectifier design based on MOSFET technology (90W PIANO achieving over 93.8 per cent at full load and +40 °C ambient temperature) reduces the need for system cooling and further increases reliability according to the company: the units offer very low losses even in idle or standby mode at < 0.5W.
High efficiency and optimised thermal design allow polycarbonate housings to be used, reducing weight and providing a robust impact resistant enclosure. The use of a plastic housing means the small, low power PIANO power supplies can be operated without grounding, saving additional installation time and cabling costs. The PIM60 and PIM90 power supplies are available with either screw terminals or time saving push-in terminals and PULS devices are optimally prepared for automated wiring processes. The PIANO-PIM range meets all international safety agency approvals and are CE marked.
