High-Power Converters in Industry

Typical modern industrial processes need a variety of power conversion equipment - high power AC/DC and DC/DC converters, battery chargers/conditioners and power factor correction front ends. RECOM and its subsidiary Power Control Systems as specialist for customised solutions, has long experience of providing high-quality and reliable single- and three-phase battery chargers with output power ratings of 3.2kW up to 11kW and even higher with cascaded products. Battery conditioning functions can be included and standalone power factor correction ‘front ends‘ are available up to 4kW rating. Some parts are bi-directional for charge balancing. A range of 250W DC/AC inverters is also available. The following designs are intentionally developed as platform solutions, which enable RECOM to modify fast, easily and cost efficient these solutions to different customer needs.

Industrial AC/DC Converters

Three-phase AC input battery chargers are available from RECOM with ratings at 3.2kW (SA3200 series) and 5kW (SA5000 series) which can be cascaded up to 20kW. The SA3200 series also operates with DC inputs up to 800V. Outputs from both series are available suitable for for 24Vnom up to 110Vnom (and all in between 36/48/72/96).

A unique part, the SD2800 series, operates at nominal 44V or 24V three-phase AC input and provides 28V or 14V respectively at 2.8kW and 1.4kW. The product is also available with DC inputs, nominal 44V, 48V, 60V or 80V.

The SAB10000 series provides 10kW of battery charging from three-phase AC (20VDC output) or 600VDC nominal input (24VDC output) but is also bi-directional so that battery charge can be returned to the AC, or optionally 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.

Industrial High-power DC/DC Converters

The SD1200 series of 1.2kW DC/DC converters is available from RECOM with flexible input/output voltage levels. With railway application approvals, the product is also suitable for general industrial use, with five DC input ranges available covering 16.8V to 170V and three DC output variants, nominal 24V, 48V and 110V.

The SD2800 series is a non-isolated 2.8kW DC/DC converter with a selection of nominal input/output combinations. The product can also optionally be powered from three-phase low voltage AC.

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 power supplies generates optionally 24V or 48V from the high voltage battery and is rated at 4kW with high efficiency. The 19“ rack product can be baseplate- or liquid-cooled.
