PSUExcelsys Technologies (Cork, Ireland) introduced its XSolo family of 1U-high, single-output switching power supply units (PSUs). The XSolo family is offered in a convection-cooled 504-W open-frame U-channel form-factor model (6.8 W/ and an enclosed, fan-cooled chassis model that delivers up to 1008 W (13.6 W/ Capable of achieving 92 percent efficiency, these PSUs meet the exacting requirements of medical, industrial, IT and military COTs applications. The XSolo family features dual safety agency certification: EN60950-1 for industrial applications and EN60601-1, 2nd and 3rd edition for medical applications—fully meeting the stringent creepage and clearance, 4-kV AC isolation and <300-uA leakage current requirements. The family also meets the voltage dip and interruption requirements of SEMI F47, as well as the environmental conditions per MIL-STD-810. The XSolo platform offers system integrators standard features such as:

  • Variable fan speed
  • 12-V/300-mA isolated bias supply.
  • Remote ON/OFF, output voltage control.
  • Parallel operation for higher power applications.
  • Nominal output voltages of 24 V and 48 V with wide adjustment ranges and user-defined setpoints.
