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.

Murata Power Solutions MEU1 series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The MEU1 has been recognised by Underwriters Laboratory for functional insulation, 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 further isolation/insulation systems must form a barrier between these circuits and any user-accessible circuitry according to safety standard requirements. REPEATED HIGH-VOLTAGE ISOLATION TESTING It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materials, construction and environment. The MEU1 series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enamelled wire. While parts can be expected to withstand several times the stated test voltage, the isolation capability does depend on the wire insulation. Any material, including this enamel (typically polyurethane) is susceptible to eventual chemical degradation when subject to very high applied voltages thus implying that the number of tests should be strictly limited. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from specified test voltage. This consideration equally applies to agency recognised parts rated for better than functional isolation where the wire enamel insulation is always supplemented by a further insulation system of physical spacing or barriers. SAFETY APPROVAL The MEU1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for functional insulation, file number E151252 applies. The MEU1 Series of converters are not internally fused so to meet the requirements of UL 60950 an anti-surge input line fuse should always be used with ratings as defined below. MEU1S03xxxC: 0.50A MEU1S05xxxC: 0.50A MEU1S12xxxC: 0.25A All fuses should be UL approved and rated to at least the maximum allowable DC input voltage.

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 2.2μs and output capacitance of 10μF, are shown in the table below. The product series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.
