CoolX600 power supplies now feature PMBus communication

March 31, 2017

Cork, Ireland. Excelsys Technologies, a manufacturer of modular user-configurable and single-output power supplies, announces that its CoolX600 Series 600-W convection-cooled modular power supplies are now available with a PMBus (Power Management Bus) communication option. In addition to being a PMBus adopter, Excelsys is a member of the System Management Interface Forum (SMIF).

PMBus is an open-standard power-management protocol that offers system builders a standard way to communicate with power converters over a digital communications bus by providing a full set of commands and data structures required by power control and management components. The CoolX Series PMBus interface facilitates the communication of operating parameters, such as output voltage, output current, and internal temperature, with other PMBus-enabled devices. It also provides the remote adjustment of parameters, such as output voltage level and current limit as well as control features, such as power supply and individual output enable/inhibit.

The convection-cooled CoolX600 Series is the latest user-configurable modular power supply from Excelsys Technologies. It delivers 600-W of output power without fan-assisted cooling from a compact 8.5 x 4.5 x 1U package. Typical efficiency is greater than 93%, and it offers a typically 25% longer lifetime than competitive power supplies, the manufacturer said. The supply comes with a five-year warranty.

Enhanced thermal performance for the CoolX Series may be obtained with system fans or additional external conduction cooling, resulting in even higher system reliability. Other features include 4-kV input surge immunity and the ability to withstand input voltages of up to 300 VAC. Additional features include SEMI F47 compliance and operation at 5000-m altitude. A 25-W standby power output—offering, effectively, another output for system intelligence, cooling fans, displays etc.—is a standard feature.

The CoolX600 is available with full safety certifications to UL/EN60950 and UL/EN60601 3rd and 4th Edition (EMC) for both industrial and medical applications. Medical features include BF rating (Body Floating), dual fusing, 2 x MOPP, <300-μA leakage current.

The CoolX600 can be populated with up to four CoolMods, providing up to four isolated DC outputs ranging from 3.0 V to 58.0 V. Outputs can be configured to the required set point voltages and connected in parallel for higher output current and/or higher output voltages. Mounting options include base, side and DIN rail alternatives.

Dermot Flynn, sales director of Excelsys Technologies, said, “Adding PMBus communication to the already exceptional CoolX power supply allows medical, industrial, and defense systems developers the option of deploying intelligent 600-W, high-reliability, silent-in-operation power solution. Our revolutionary designs and feature sets continue to keep us ahead of our competitors.”

Typical applications include medical clinical diagnostic equipment, medical lasers, dialysis equipment, radiological imaging, clinical chemistry, industrial test and measurement, industrial machines, automation equipment, printing, telecommunications, audio equipment, high-reliability harsh industrial electronics, and radar.

Other products in the Excelsys range include the UltiMod and Xgen user-configurable modular power supplies and single-output Xsolo power supplies, which are suitable for applications including industrial, medical, laser, communications, IT, wafer fabrication, optical inspection, wire bonding, and automated test equipment.
