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) 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.

Nominal output voltage is achieved at 50% load and output voltage drops at a rate of 30mv per amp for 12V output, 120mV per amp for 24V output, and 500mV per amp for 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, please contact Murata sales for external ORing FET board or external 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 MVAC400.A04 Page 2 of 6 MVAC400 Series 400W High Density AC-DC Power Supply 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 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. Radiated emission results vary with system enclosure and cable routing paths. STATUS AND CONTROL SIGNALS Parameter Conditions PS_ON This signal must be sinked low (>2mA) to +5V_AUX_RTN to turn on the main and Fan (V2) output. The +5V_AUX output is on when AC is applied. PWR_OK 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 up to +5V_AUX is provided.

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. P-Q CURVE, DUCTED FLOW 13mm [0.5in] all sides Air Flow 0.0100 * Ambient Temperature Measurement Static Pressure (in. w.g.)

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.

TOLERANCE IS 0.65MM [0.025IN] NOTES: 1. Protective bonding conductor from the end product protective earthing terminal must be tied to TB1. For optimum EMI performance, 4 mounting holes must be tied to the end product protective earthing terminal. 2. This power supply requires mounting on standoffs 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. Also, the primary and secondary heatsinks must be separated with reinforced insulation. 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.
