Convection cooled 600W power supplies add PMBus communication
PMBus 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 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, current limit as well as control features such as power supply and individual output enable/inhibit.
The convection-cooled CoolX600 Series provides 600W without fan assisted cooling from a compact 8.5 x 4.5 x 1U package. Typical efficiency is greater than 93% and the thermal performance offers typically 25% longer lifetime than other systems with a five year warranty.
Enhanced thermal performance may be obtained with system fans or additional external conduction cooling resulting in even higher system reliability. Other features include 4KV input surge immunity, and the ability to withstand input voltages of up to 300VAC making it ideal for use in remote locations and those subject to input voltage disturbances. Additional features include SEMI F47 compliance, and operation at 5000m altitude. A 25W 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. Stand-out medical features include BF rating (Body Floating), dual fusing, 2 x MOPP and under 300μA leakage current.
The CoolX600 can be populated with up to 4 CoolMods, providing up to 4 isolated DC outputs ranging from 3.0V to 58.0V. Outputs can be configured to the required set point voltages and connected in parallel of series for higher output current and/or higher output voltages.
PMbus offers system integrators analogue and digital management and is user field configurable with Plug and Play power. All outputs are isolated and may be connected in series or parallel to achieve higher output voltages or currents. Mounting options include base, side and Din Rail alternatives
“Adding PMBus communication to the already exceptional CoolX power supply allows medical, industrial and defence systems developers the option of deploying intelligent 600 watt, high reliability, silent in operation power solution,” Dermot Flynn, Sales Director of Excelsys Technologies.
Typical applications include medical clinical diagnostic equipment, medical lasers, dialysis equipment, radiological imaging and clinical chemistry. The suppliers are also used in industrial test and measurement and automation equipment.
