According to Murata, the 50 watt IRS-Q48 series from Murata Power Solutions offers ‘market-leading’ efficiency using technology for fixed frequency switching power supply architectures, in an ‘industry standard’ 1/16th brick pinout.
Murata’s IRS-Q48 series is designed to provide basic insulation with 2250 Vdc input-to-output isolation and a fully regulated DC output. The IRS series includes modules with outputs of 3.3, 5 and 12 Vdc with up to 50 watts of output power.
Murata says that the universal Vin range of 18 – 75Vdc meets the requirements of EN50155 for nominal input voltages of 37.5Vdc and 48Vdc including brown out and transient conditions.
The IRS-Q48 series is available with an option for a standard or a flanged baseplate for various conduction cooling configurations including cold wall mounting.
