Units VDC GΩ GENERAL CHARACTERISTICS Parameter Switching frequency PRODUCT OVERVIEW The MEV3 series is a new range of high performance 3W DC/DC converters, offering 3W of available output power in a previously rated 2W package capable of operation over the full industrial temperature range of -40ºC to 85ºC. Available in an industry standard SIP package, with a pin compatible power upgrade path from the 1W NMV/MEV and 2W NMK series’, they are ideally suited for providing local supplies on control system boards with the added benefit of 3kVDC galvanic isolation.

The tolerance envelope is the maximum output voltage variation due to changes in output loading. TECHNICAL NOTES ISOLATION VOLTAGE ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation. Murata Power Solutions MEV3 series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 3kVDC for 1 minute. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” For a part holding no specific agency approvals, such as the MEV3 series, both input and output should normally be maintained within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages and the part should never be used as an element of a safety isolation system. The part could be expected to function correctly with several hundred volts offset applied continuously across the isolation barrier; but then the circuitry on both sides of the barrier must be regarded as operating at an unsafe voltage and fu.
