DESCRIPTION

The MEU1 series is a new range of ultra miniature

through hole 1W DC/DC converters, available in

a ZIP style pinout. The MEU1 series offers 1W

of available output power over the industrial

temperature range of -40ºC to 85ºC. They are

ideally suited for providing local supplies on

control system boards.

With the added beneﬁt of 1kVDC galvanic

isolation to reduce switching noise and allows

the device to be conﬁgured to provide an isolated

negative rail in systems where only positive rails

exist.

MEU1 Series Isolated 1W Single Output DC/DC Converters APPLICATION NOTES Minimum Load The minimum load to meet datasheet speciﬁcation is 10% of the full rated load across the speciﬁed input voltage range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically 1.25 times the speciﬁed output voltage if the output load falls to less than 5%. Capacitive loading and start up Typical start up times for this series, with a typical input voltage rise time of 2.

MEU1 Series Isolated 1W Single Output DC/DC Converters 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.
