Modular High Performance DC Power Supplies
Today the rationalization of infrastructure and energy expenditure without compromising performance has become a major issue. From this perspective, JEMA has developed the MOSAIC modular high performance power supply system.

ModularThree base modules: the CIME AIR 10kW module, the CIME H2O 20kW module and the system control module provide a modular solution that performs well and is flexible to power requirements, from a few kW to several hundred kW. |
Efficient95%: With productivity able to exceed 95%, a mixed cooling system and an excellent power factor, also of 95%, CIME modules minimise the constraints on infrastructure (electrical installations, air conditioning...) |
FlexibleMade-to-measure systems, standard elements: each comprising up to 4 independent insulated outputs. The same modules can attain very different tension/current/power characteristics simply by placing them in series or in parallel, on the same module as well as across modules. |
High performanceOptimal control: integrally controlled by DSP, the modules and controller incorporate optimised control algorithms that govern most of the performance factors for the power circuits, both in terms of stability and dynamics. |
CompactA quarter of the volume: in relation to a classic product of equal power, the modular approach allows a significant cut in volume of around three quarters - with a major impact on the dimensions of power supply rooms and their climate control systems. |
IntelligentOptimised, user-friendly and interactive: Accessible via a local touch screen as well as through various communication buses, the controller give full access to all working parameters and system diagnostics. |
AvailableOperational in 15 minutes: The easy replacement of standard modules allows for quick interventions for preventative or corrective maintenance, thus minimising the amount of time for which the machine must be stopped. |
