Simple Function Model AC-DC Unit Type Power Supply, High Power Model of RWS-B Series	

March 30, 2017

TDK Corporation has developed new high power models in the RWS-B Series, the small, simple function AC-DC high efficiency power supply, in the TDK-Lambda brand: 1000W output model (RWS1000B) and 1500W output model (RWS1500B). These two models have been added to the lineup that ranges from 50W to 600W output model, and have been sold since October 2013 to meet the demands for high power and small size for customers’ equipment. TDK-Lambda Corporation will begin sales of these models in March.

The RWS-B Series is a simple function power supply with its basic performance maintained and additional functions optimized. In addition, the small and high efficiency power supply will improve efficiency under light loads and reduce power consumption at standby mode, thereby contributing to the reduction of the environmental burden from low power consumption to high power consumption.

RWS1000B/RWS1500B has an expected product life of more than five years, which follows the product concept of the RWS-B Series and maintains the same reliability in a severe environment. In addition, this model is compliant with Class B noise regulations, which achieves simple noise reduction for customers’ equipment.

In addition to the standard type, the ME option items compliance with medical safety standard and other options are available.
