Emerson Network Power has unveiled the µMP4, which is the company's latest configurable ac-dc power supply that claims to rival the cost of non-configurable power supplies, while providing market-leading density, efficiency, reliability and agency approvals.

Available now, starting at 202 US Dollars per unit in production quantities, the low-profile 1U (1.75 inch) µMP4 offers a power density of 13.9 W per cubic inch and operating efficiency of up to 91 percent typical at full case load. The case can deliver up to 600 W of output power with no minimum load requirement. In addition, users can mix-and-match up to four modules with outputs ranging from 0.9 V to 60 V, enabling nearly limitless output power configurations.    

Designed to ensure high efficiency and reliability – even in extreme environmental conditions – the µMP4 is rated for performance at temperatures from -40 to 70 degrees Celsius. The device can withstand a shock/vibration of more than 50 G, contributing to a high demonstrated mean-time between failures of more than 550,000 hours at full load. Conformal coating is also available as an option.    

The µMP4 accepts a wide input voltage range of 85 Vac to 264 Vac and is equipped with active power factor correction rated at 0.99 typical to minimize input harmonic current distortion.     

Microcontrollers integrated into the case are supported by Emerson Network Power's intuitive GUI-based PMBus control software, which can be downloaded free from the company's web site. The software provides OEMs with superior flexibility, including real-time input voltage, current and temperature monitoring to provide at-a-glance performance confirmation for the entire power supply.     

The µMP4 is pre-certified with a host of safety specifications – including UL, CSA, VDE, BABT, BSMI, CB, and CE certifications – to ensure rapid, cost-effective power provisioning off-the-shelf and enable shorter design-to-manufacture timelines. The µMP4 power supply meets EMI Class B and EN61000 standards for conducted noise and Restriction of Hazardous Substances (RoHS) directives. The power supply is also equipped with full EN60601 medical safety approvals, making the µMP4 ideal for certain medical applications, as well as industrial, process automation, robotics and telecommunications OEMs.
