ABSOPULSE Electronics’ PFC 4K5-3U19 Series modular, rack-mount AC-DC power supply system with PFC input delivers 4500W or 3000W with N+1 redundancy.
This system is built with three heavy-duty 1500W PFC 1K5 power supply modules assembled on a 3U x 19” rack-mount cradle (the CR 3U-3). 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, which contributes to seamless servicing of the system in the field.
The PFC 1K5 modules each accept a 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. Custom input/output voltages are available. A built-in redundancy diode allows for parallel connection and N+1 redundant operation. The redundancy diode also allows for the option of a battery to be connected to the output for back-up purposes. The units are each equipped with a Form C module fail alarm as well as 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 PFC 1K5 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 EN55032 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.
The series is suitable for operation in power utility, industrial control and telecommunications environments.
ABSOPULSE offers an extensive range of these heavy-duty, modular, power systems which can readily be adapted to customer requirements. We also provide fully-custom solutions with short delivery times and low set-up costs. We would be pleased to discuss the power conversion requirements of your next project.
