High-performance 500W AC/DC power supply for medical devices and industrial test equipment

Designed to solve a multitude of power challenges for next-generation medical devices and industrial test equipment, SL Power Electronics has unveiled the MINT1500 AC/DC power supply. The high-performance MINT1500 meets design engineers’ requirement for a highly-efficient 500W power supply that offers a flexible horizontal or vertical configuration in a compact 3.3 x 7 x 1.5 package - ideal for space-constrained applications. Power dense and highly efficient, the units feature a universal AC input of 90 to 270VAC and DC output range from 24V to 56V. The small form factor allows the MINT1500 to fit easily into a 1U or 2U chassis and provides 350W for convection cooling, higher than any power supply in its class, or 500W with moving air. They are approved to AAMI ES/CSA C22.2/EN/IEC60601-1, third edition with 2x Means of Patient Protection (MOPP) isolation. Input and output monitoring alarms plus 12V/0.8A fan output and 5V standby voltage are standard features of the MINT1500 family. To better meet the specific needs of medical and industrial applications, AC and DC connections are placed on opposite sides of the power supply. “The superior 350W convection performance, 93% efficiency and approval to IEC60601-1 3rd edition, EN60950 2nd edition standard make our new MINT1500 the go-to internal power supply for medical devices as well as industrial applications such as test and measurement,” said Maggie Nadjmi, product manager for SL Power Electronics. “In addition, the horizontal or vertical mounting gives designers a flexible approach to power and eliminates the need for a second model to meet a configuration challenge. Another benefit is that the MINT1500 offers current share for system redundancy or a path for higher power application all with only one SKU.” With an efficiency rating of 93%, the MINT1500 provides a lower heat signature, reducing end users’ energy costs and helping to advance customers’ green power initiatives. Moreover, further costs are reduced through the power supply’s forced current share that provides a higher power architecture - eliminating the need for an external circuit. This frees up valuable circuit board space and saves considerable money in design and development. The MINT1500 power supply operates from -10C to 70C and all models are fully self-protected against short circuit, overload, and over-temperature conditions. Protected by a three-year warranty, the RoHS compliant power supplies meet stringent EMC requirements for applications requiring Class B conducted. In addition, the models are rated at 500,000 hours of calculated mean time between failure (MTBF), says the company.
