Nominal output voltage is achieved at 50% load and output voltage increases/drops at a rate of: * 30mv per amp for the 12V output* * 120mV per amp for the 24V output * 500mV per amp for the 50V output. Startup of parallel power supplies is not internally synchronized. If more than 400W combined power is needed, start-up synchronization must be 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, use the AFR model or if the AFD model is selected please contact Murata sales for external ORing FET board or external ORing FET reference circuit design (also see Applications Note ACAN-42). 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 com load must not exceed 12W, external ORing devices must be used. www.murata-ps.com/support MVAC400.B03 Page 2 of 3 MVAC400 Series 400W 3" x 5" High Density AC-DC Power Supply Converter EMISSIONS AND IMMUNITY Characteristic Standard Compliance Input Current Harmonics Voltage Fluctuation and Flicker IEC/EN 61000-3-2 IEC/EN 61000-3-3 EN 55022 FCC Part 15 IEC/EN 61000-4-2 IEC/EN 61000-4-3 IEC/EN 61000-4-4 IEC/EN 61000-4-5 IEC/EN 61000-4-6 IEC/EN 61000-4-8 IEC/EN 61000-4-11 Class A Complies Class B Class B Level 4, Criterion 2 Level 3, Criterion A Level 4, Criterion A Level 3, Criterion A Level 3, 10V/m, Criterion A Level 3, Criterion A Level 3, Criterion B Conducted Emissions ESD Immunity Radiated Field Immunity Electrical Fast Transient Immunity Surge Immunity Radiated Field Conducted Immunity Magnetic Field Immunity Voltage dips, interruptions E 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. MI CONSIDE 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. IONS STATUS AND CONTROL SIGNALS Parameter Models PS_ON Conditions MVAC400-xxAF This pin 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 of MVAC400-xxAFD the PS_ON signal, and comes up automatically when the input AC or input DC voltage is applied within their specified operating ranges. MVAC400-xxAFR MVAC400-xxAFT 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 MVAC400-xxAFJT voltage 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. PWR_OK All Models Open collector logic goes high 50-200ms after the main output is within regulation; it goes low at least 6msecs before loss of regulation. Internal 10K pull up to +5V_Aux is provided. Applications using the PWR_OK signal should maintain a minimum load of 5W on the main or fan output. 1. Noise and ripple is measured at an oscilloscope jack on the output, 20MHz bandwidth, and with 0.1F ceramic and 10F aluminum electrolytic capacitors across the output pins. 2. Unless otherwise specified all measurements are taken at 120Vac input and 25C ambient temperature. 3. Fan (V2) regulation band applies from 0.1A to 1A load with a minimum of 10W load on the main (V1) output. 4. Fan (V2) has overvoltage protection (tracking V1) and short circuit protection. Overloading the Fan (V2) output can result in permanent damage to the unit. 5. 24V and 50V models may exhibit up to 5% turn on overshoot for loads less than 4% of full load. 6. Load regulation for droop version models (MVAC400-xxAFD and MVAC400-xxAFR) is based the calculated droop voltage 1.5% (see current sharing section for droop characteristics). 7. No load Input power varies by model and by input line. Measurement is difficult to make due to burst mode operation. Please contact Murata sales if additional information is required. 8. All three output returns are isolated from each other (see isolation characteristics section); the returns may be tied together externally. 9. Load steps beginning from combined loads on the main and fan outputs of less than 5W may result in a transient undershoot outside of the specification limits. 10.For MVAC400-xxAFR models only: Measured with 220F capacitance across main output.

Performance derating curves are provided which can be used as a guideline for what can be achieved in a system configuration with controlled airflow at various input voltage conditions. The air flow 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 influences local temperatures. The wind tunnel test setup was constructed to produce a flow with a slight back pressure to induce both flow conditions by providing a small gap between the power supply and duct walls of 0.5" (13mm). The optimal and characterized airflow direction is from the input connector to the output connector (see diagram below). The P-Q flow 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 flows inherent in the elevated temperature test system.

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.
