High-power power supplies

These are compact high density, high power supplies and power supply sub-assemblies, made for integration into your technically advanced product. One of the most difficult parts of a power supply over 1kW is to design a reliable PFC front-end (Power Factor Correction). We have proven board sets with demonstrated MTBF of 500,000 to > 1 million hours. Let our designers assist you with the integration of our high performance isolated or non-isolated PFC bulk converters into your design. We can accommodate special input power cycling requirements and unusual dynamic load profiles.

We can provide your system with a low voltage bus (12 to 56VDC) for RF power modules, battery charging, telecom back planes, house keeping or high voltage bus (100 to 400VDC) for motor controllers, UPS battery charging, or the bus voltage before the high voltage step-up circuit to power RF or X-ray tubes.

Other features include: paralleling supplies to 10’s of kilowatts of output, hot plug modules, N+1 redundancy, full universal input range, low ripple & noise, wide operating temperature range, and standard compact case sizes of 5 x 3RU, 5 x 2RU and 5 x 1 RU. Supplies and board sets are designed to meet all international safety & EMI standards.

Our Intelligent Controller uses a built-in Micro-Controller Chip and is used with our Intelligent Power System. This Controller embedded as part of the individual power shelves and is capable of controlling and monitoring up to six rectifiers in a 3U-23” standard shelf. This can also be designed into a power supply or battery charger, making it a standalone Intelligent Power Supply or an Intelligent Battery Charger.

This allows users to remotely configure, control and monitor all parameters of the power and battery back-up system via RS232 or by other standard communication protocols. Multiple shelves with built-in controllers can be paralleled for high-power applications. In multiple configurations, the controller is set up in an active and passive scheme to provide full system and battery control and monitoring.

Easy to use commands are implemented to configure the system controls and alarms. Using the command editor, the user can program parameters such as battery low voltage disconnect, battery float voltage temperature compensation, battery charge current and equalize battery. Additionally, the use can remotely query the status of the rectifier system. All alarms are programmable as minor or major alarms.
