4500W Rack-mount AC/DC power supply system with Hot-pluggable 1500W Modules

The 4.5kW system is built with three, heavy-duty 1.5W (PFC 1K5) power supply modules assembled on a 3U x 19” rack-mount cradle. The cradle is constructed with high-grade stainless steel and mechanical features that allow for easy insertion of the 5” x 5” x 12” PFC 1K5 units. The modules are hot-pluggable and can be inserted or removed without powering the system down.



The 1.5kW modules each accept universal ac-input voltage (95-264Vac) and are available in several different output configurations including 24Vdc/60A, 48Vdc/30A, 54Vdc/27A, 110Vdc/13A or 125Vdc/12A. Customer specified input and output voltages are available. A built-in redundancy diode allows for parallel connection to increase current available to the load, as well as for N+1 redundant operation.



The PFC 1K5 units are each equipped with an AC-module fail alarm (Form C) and a diagnostic output ON LED. They have generous design headroom and are rated for operation over a 0ºC to 50ºC temperature range without de-rating. Each unit is cooled by a high quality built-in fan.



The modules comply with EN61000-3-2 and EN61000-3-12 directives for low input harmonic distortion as well as EN/UL60950 and equivalent industrial safety standards. They are filtered to meet EN55022 Class A EMI standards with large margins. Efficiency at full load is typically 80%. Protection features include 4300Vdc input to output isolation, output current limiting with non-hiccup type short-circuit protection and thermal shutdown with self-resetting.
