To meet customer requirements for higher power PSs, Myrra came with three new families of 20W (4722x), 40W (4723x) and 60W (4726x) compact-sized switched mode power supplies with output voltages of 3.3, 5, 9, 12, 15, 18 and 24VDC. Input voltages are in the range of 85VAC-264VAC/47-63Hz or 120VDC-370VDC.

The very low Stand-by Power Consumption of only 0,1W meets the requirements of Energy Star and EC Code of Conduct. The encapsulated design ensures high reliability and isolation strength.

All used materials for encapsulation are UL94-V0 compliant, which is an important requirement for electronic equipment. With a very low level of conducted and radiated emissions, these power supplies conform to EN55014 CLASS B, EN55032 CLASS B and FCC Part 15.

Wide operation temperature range allows using the 472Xx family of power supplies in harsh environments of up to 50°C without derating and up to 80°C with power derating.
DC Output characteristics are also exceptional with ±3% output voltage accuracy, ±3% output voltage line regulation accuracy and max 20mV p-p ripple and noise figure.

Other characteristics include overcurrent protection, output short circuit protection, and MTBF at 200k Hours minimum. Dielectric strength (Primary to Secondary) is 4kVac/5mA, max 3sec.
