Industrial Power Conversion Products

Three-phase AC input battery chargers are available from RECOM Power Systems with ratings at 3.2kW (RMOC3200 series) and 5kW (RMOC5000 series), which can be cascaded up to 20kW. The RMOC3200 series also operates with DC inputs up to 800V. Outputs from both series are available suitable for 24Vnom up to 110Vnom (and all in between such as 36/48/72/96V) systems.

Chargers/conditioners are also offered at 2kW single-phase AC (MA2000 series) and 11kW three-phase AC (MA11000 series). These products can be programmed to charge and discharge batteries for test and conditioning for optimum battery life-time and availability. Both series can operate with a very wide range of battery voltages. The SAB10000 series provides 10kW of battery charging from three-phase AC (20VDC output) or a 600VDC nominal input (24VDC output) but is also bi-directional so that battery charge can be returned to the AC, or optionally the DC supply for energy balancing applications.

Modular stand-alone power factor correction ‘front ends’ are available at 800W, 1600W, and 3200W (single-phase AC input) and at 4kW (three-phase AC input). Products are available in 19“ rack, open frame, or chassis formats, or to customer specification. These PFC modules are key for improving power quality and efficiency in demanding industrial equipment.

In industry, fork-lift trucks and other materials handling equipment often use traction batteries rated from 320V to 600V. The SD4000 series of on-board DC/DC converters generate optionally 24V or 48V from the high voltage battery and are rated at 4kW with high efficiency. The 19“ rack product can be baseplate- or liquid-cooled, making it suitable for rugged environments. These traction battery power supplies offer a reliable power source for vehicle control systems and auxiliary functions.
