## **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.

|Parameter|Models|Conditions|

|PS_ON|All models except<br>as noted below.|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<br>of the PS_ON signal and comes upautomaticallywhen the input AC or input DC voltage is applied within their specif ed operatingranges.|
||MVAC250-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 voltage<br>is applied within their specif ed operatingranges. Pullingthispin low(sink current >2mA)to +5V_AUX_RTN will disable the main and fan outputs.|
|PWR_OK|All models|Open collector logic goes high 50-200 msec after main output is in regulation; it goes low at least 6 msec before loss of regulation. Internal 10K pull<br>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. Noise and ripple is measured at an oscilloscope jack on the output, 20MHz bandwidth, and with 

- 0.1μF ceramic and 10μF aluminum electrolytic capacitors across the output pins. 

2. Unless otherwise specifi ed all measurements are taken at 120Vac input and 25°C 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. See current sharing option section for droop characteristics. 

7. No load Input power varies by model and by input line. Measurement is diffi cult 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 transient undershoots outside of the spec limits.

## ~~OO~~ **THERMAL CONSIDERATIONS** 

System thermal management is critical to the performance and reliability of the MVAC series power supplies. 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.

The natural convection data is obtained from a horizontally mounted power supply with un-obstructed fl ow at room temperature. 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.

## SAFETY CONSIDERATION NOTES: 

1. 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. This product is subject to the following operating requirements and the Life and Safety Critical Application Sales Policy: Refer to: - 

http://www.murata ps.com/requirements/ 

5. Used only in non-tropical conditions. 

6. Double pole/neutral fusing. 

Dimensions: 3.0" x 5.0" x 1.4" (76.2mm x 127mm x 35.6mm)
