Nominal output voltage is achieved at 50% load and output voltage increases/ drops at a rate of: • 48mv per amp for 12V output • 192mV per amp for 24V output MVAC250-12AFD • 800mV per amp for 50V output. Startup of parallel power supplies is not internally synchronized. If more than 250W combined power is needed, start-up synchronization must be MVAC250-24AFD provided by using a common PS_ON signal. To account for ±10% full load current sharing accuracy and the reduction in full load output voltage due to droop, available output power must be derated by 15% when units are operated in parallel. Current sharing can be achieved with or without remote sense connected to the common load. If ORing protection is desired, please contact Murata sales for external ORing FET board or external MVAC250-48AFD ORing FET reference circuit design. Aux (V3) output can be tied together for redundancy but total combined output power must not exceed 10W, external ORing devices must be used. Fan (V2) can be tied together for redundancy but total combined output power must not exceed 12W, external ORing diodes can be used. www.murata-ps.com/support MVAC250.C03 Page 2 of 9 MVAC250 Series 250W 3" x 5" High Density AC-DC Power Supply Converter EMISSIONS AND IMMUNITY Characteristic Standard Compliance Input Current Harmonics IEC/EN 61000-3-2 Class A Voltage Fluctuation and Flicker IEC/EN 61000-3-3 Complies EN 55022 Class B Conducted Emissions FCC Part 15 Class B ESD Immunity IEC/EN 61000-4-2 Level 4, Criterion 2 Radiated Field Immunity IEC/EN 61000-4-3 Level 3, Criterion A Electrical Fast Transient Immunity IEC/EN 61000-4-4 Level 4, Criterion A Surge Immunity IEC/EN 61000-4-5 Level 3, Criterion A Radiated Field Conducted Immunity IEC/EN 61000-4-6 Level 3, 10V/m, Criterion A Magnetic Field Immunity IEC/EN 61000-4-8 Level 3, Criterion A Voltage dips, interruptions IEC/EN 61000-4-11 Level 3, Criterion B EMI CONSIDERATIONS For optimum EMI performance, the power supply should be mounted to a metal plate grounded to all 4 mounting holes of the power supply. To comply with safety standards, this plate must be properly grounded to protective earth (see mechanical dimension notes). Pre-compliance testing has shown the stand-alone power supply to comply with EN55022 Class A radiated emissions. Class B radiated emissions are achievable with a metal enclosure. Radiated emission results vary with system enclosure and cable routing paths. SAFETY CONSIDERATIONS 1. This power supply is a component level power supply intended for use in Class I or Class II applications. Secondary ground traces need to be suitably isolated from primary ground traces when used in Class II applications. 2. When the power supply is used in Class II equipment, all ground traces and components connected to the primary side are considered primary for spacing and insulation considerations. STATUS AND CONTROL SIGNALS – MVAC250-xxAFD ONLY Parameter Models Conditions All models except This signal must be pulled low (sink current >2mA) to +5V_AUX_RTN to turn on the main and Fan (V2) output. The +5V_AUX output is independent as noted below. of the PS_ON signal and comes up automatically when the input AC or input DC voltage is applied within their specified operating ranges. PS_ON This pin is pulled high internally and so all three outputs (main, Fan output and +5V_AUX) come up automatically when the input AC or input DC voltage MVAC250-xxAFT is applied within their specified operating ranges. Pulling this pin low (sink current >2mA) to +5V_AUX_RTN will disable the main and fan outputs. Open collector logic goes high 50-200 msec after main output is in regulation; it goes low at least 6 msec before loss of regulation. Internal 10K pull PWR_OK All models up to +5V_AUX is provided. Applications using PWR_OK signal should maintain a minimum load of 5W on the main or fan output. 1.

Performance derating curves are provided which can be used as a guideline for what can be achieved in a system confi guration with controlled airfl ow at various input voltage conditions. The air fl ow curves are generated using an AMCA 210-99 and ASHRAE 51-1999 compliant wind tunnel with heated inlet air and a controlled CFM providing a duct test section having a calculated average LFM. A correlation between the test setup and the actual system environment is paramount to understanding what can be achieved in an actual system. In a power supply of this density, cooling air moving both through the unit as well as around the unit strongly infl uences local temperatures. The wind tunnel test setup was constructed to produce a fl ow with a slight back pressure to induce both fl ow conditions by providing a small gap between the power supply and duct walls of 0.5" (13mm). The optimal and characterized airfl ow direction is from the input connector to the output connector (see diagram below). The P-Q fl ow curve for this test setup is also shown below.

At elevated temperature the power supply data is taken while it is surrounded by a large vented enclosure to minimize forced cross fl ows inherent in the elevated temperature test system.

For optimum EMI performance, while maintaining Class I safety isolation all 4 mounting holes must be tied to the end product protective earthing terminal. To maintain Class II safety isolation mounting holes MTG1 and MTG2 need to be isolated from protective earth and should use standoffs of non-conductive material. 2. This power supply requires mounting standoffs of minimum 6mm in height. If there is risk of chassis deformation or shorter standoff height is required, an appropriate insulator must be used under the power supply with adequate extension beyond the outline of the power supply.

Protective bonding conductor from the end product protective earthing terminal must be tied to TB1. For optimum EMI performance, while maintaining Class I safety isolation all 4 mounting holes must be tied to the end product protective earthing terminal. To maintain Class II safety isolation mounting holes MTG1 and MTG2 need to be isolated from protective earth and should use standoffs of non-conductive material. 2. This power supply requires mounting standoffs of minimum 6mm in height. If there is risk of chassis deformation or shorter standoff height is required, an appropriate insulator must be used under the power supply with adequate extension beyond the outline of the power supply. In all cases,the applicable safety standards must be applied to ensure proper creepage and clearance requirements are met. 3. The primary heatsink is considered a live primary circuit, and should not be touched. It is recommended that the primary heatsink be kept at least 3.5mm from chassis and 7mm from secondary circuits. In all cases, the applicable safety standards must be applied to ensure proper creepage and clearance requirements are met. 4.
