Electronica visitors invited to test custom power supply performance
1 min read
Emerson Network Power has launched a range of configurable power supplies which it claims can match the performance of equivalent multi-output custom power supplies. The µMP, iMP and iVS families on show at electronica are part of the range of medium to high power supplies from the company's Embedded Power business and cover the power load range up to 3kW and DC voltage outputs up to 60V.
The iMP and iVS power supplies allow users to change output voltage and current through programmed configuration settings, without any hardware change. The entry level µMP range can be configured to the user's specifications before shipping and In each case, power outputs can be altered.
According to Emerson, the advanced design of the µMP, iMP and iVS devices means that they can match the performance of custom multi output supplies, without the limitation of fixed specification, inflexible hardware.
Chris Jones, marketing director of the Embedded Power business of Emerson Network Power, said: "This latest generation of power supplies has crossed the performance threshold such that multi output custom designs no longer offer any material performance advantage over the off the shelf configurable equivalent. So confident are we in our configurable power supplies that we are asking visitors to our stand at Electronica 2010 (B2.461) to take our Custom v. Configurable Challenge. If they bring their custom multi output power supply design to the stand, we will show them a configurable power supply that can match its specifications in terms of efficiency, power output and density."
The most recent addition to the company's configurable power supplies is the µMP1. The low profile, 1U (1.57in) µMP1 has six available expansion slots, enabling users to mix and match modules for up to 12 outputs ranging from 0.9 to 60V. It offers a power density of 13.9W per cubic inch and operating efficiency of up to 91% typical at full case load. The case can deliver up to 1200W of output power with no minimum load requirement. The µMP1 accepts an input voltage range of 85 to 264Vac and is equipped with active power factor correction rated at 0.99 typical to minimise input harmonic current distortion.
