Excelsys Technologies announces the availability of PMBus communications on its Xsolo series of 1U, single output PSUs. Xsolo units equipped with an optional I2C digital interface can be remotely monitored by system supervisory equipment utilising industry standard PMBus protocols. 

The XSolo family is offered in a both convection-cooled 504W open-frame U-channel form-factor model and an enclosed, fan-cooled chassis model that delivers up to 1008W. Capable of achieving 92% efficiency, these ultra-compact and rugged PSUs meet the exacting requirements of medical, industrial, IT and military COTs applications. Additionally, both models carry a five-year warranty.

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, 4kV ac. isolation and less than 300uA leakage current requirements. The XSolo family also meets the voltage dip and interruption requirements of SEMI F47, as well as the environmental conditions per MIL-STD-810. In addition, the products are compliant with all relevant EMC emission and immunity standards.

The XSolo platform offers system integrators with a host of standard features, including variable fan speed, 12V/300mA isolated bias supply, remote ON/OFF, output voltage control and parallel operation for higher power applications. Nominal output voltages are 24 and 48V with wide adjustment ranges and user-defined setpoints.

“The addition of PMBus capabilities to our Xsolo platform is an answer to customer requests for connectivity at a systems level,” said Gary Duffy, Excelsys, CEO. “The remote monitoring of system power supply voltage, current and temperature can provide system status and remote health monitoring functionality for our customers’ end products.”
