Power Supplies Deliver 1.8-kW Punch

Excelsys Technologies’ CoolX1800 intelligent, modular power supply platform delivers 1800W of output power in 10.6 in. x 5 in x 1U package. With conversion efficiencies of up to 93%, the component offers PMBus digital communications and control and can be populated with up to six CoolMods, providing up to 12 isolated dc outputs ranging from 2.5V to 58V. A 24W, medically isolated, auxiliary supply is available as a standard feature, offering another output for system intelligence, control, and displays.


The CX18S is available with full safety certifications to IEC60950 2nd edition and is certified to the upcoming IEC62368-1 standard for industrial applications. The CX18M carries both the IEC60601-1 3rd edition and IEC60601-1-2 4th edition (EMC) standards for medical applications.

Medical features include body floating (BF) rating, dual fusing, 2 x MOPP and <300 µA leakage current. The CoolX1800 provides higher input surge protection for operation in harsh environments, reverse energy protection without the use of external blocking diodes and is also safety certified operation at altitudes of up to 5000m. Additionally, the CoolX1800 can withstand input voltages of up to 300 Vac, making it suitable for use in remote locations and those subject to input voltage disturbances.


The intelligent CoolX1800 platform offers flexibility with analog and digital control. In addition, outputs can be configured to the required set point voltages and connected in parallel/series for higher output current and voltages. CoolPacs can be paralleled for higher power and N+1 redundancy applications. The CoolX platform is user configurable, providing customers with the capability to configure and reconfigure in the field without voiding warranty or affecting safety approvals.
