Excelsys XSolo Power Supply Features PMBus Communication

Xsolo Modular Power Supply

  • I2C PMBus™ Communications Available
  • SEMI F47-0706 Compliant
  • Industry leading 5 year warranty

Excelsys Technologies, recognised as a technology leader in high efficiency modular power supply design, offers system builders the option of PMBus communication on its Xsolo family of 1U high, ultra-compact single output power supplies. The high efficiency XSolo is available in two package types delivering a market leading convection cooled 504W in an open-frame U-channel form-factor and up to 1008W in an enclosed fan cooled chassis. Both models carry a 5 year warranty.

The Xsolo may be specified with an I2C digital communications bus over which industry standard PMBus protocols may be used. PMBus is an open architecture method for communicating with power supplies and interfaces with all types of power converters.  It is owned by The System Management Interface Forum (SM-IF) to which membership is royalty free and open to all. The open architecture of PMBus ensures that any communication software will work seamlessly with power converters from any manufacturer.

The XSolo platform is MIL810, SEMI F47 Compliant, provides nominal output voltages of 24V, 36V and 48V with wide adjustment ranges and user defined set-points and ultra-high efficiency up to 92%. System integrators can take advantage of a host of other features including; variable fan speed, 12V/300mA isolated bias supply, remote ON/OFF, power good signal, output voltage control, OR-ing Diodes for N+1 redundancy and parallel operation for higher power applications. Maximum dimensions are 1U x 238mm x 128mm.

The XSolo power supply can also be provided with conformal coating and ruggedised for use in harsh environments. With convection cooled power capability of over 500W the XSolo is ideal for use in Hi-Rel MIL-COTS applications as well as acoustic sensitive laboratory and medical equipment.

To simplify product selection and inventory control the XSolo range has dual safety agency certification; EN60950 for industrial applications and EN60601-1 2nd and 3rd Edition for medical applications, fully meeting the stringent creepage and clearance requirements, 4KVAC isolation and <300uA leakage current. The XSolo is also compliant with the semiconductor manufacturing standard SEMI F47, fully meeting the voltage dips and interruption requirements. The Excelsys XSolo range is compliant with all relevant EMC emission and immunity standards.

Other products in the Excelsys range include the UltiMod and Xgen user configurable modular power supplies suitable of applications including, industrial, medical, communications, IT, wafer fabrication, optical inspection, wire bonding, and automated test equipment.
