TDK Corporation announces the development of the TDK-Lambda brand of isolated DC-DC converter TEP200-280, which supports wide range high voltage inputs from 300 to 1000 VDC. The new product satisfies customers&lqquot& needs as a step-down converter that converts high voltage obtained from renewable energy sources into an input voltage for standard power supplies used for general industrial devices. TDK-Lambda Corporation will start receiving orders in April 2018.

The TEP200-280 is an isolated board type DC-DC converter that can accept a wide range of high voltage inputs from 300 to 1000 VDC. It converts high voltage obtained from renewable energy to 280 VDC, the input voltage for standard power supply for general industrial devices. As the output voltage (280 VDC) is a general input voltage for our standard power supplies, it can be easily converted to the required voltage with our standard switching power supply at the subsequent stage.

This product does not require a fan and employs a convection cooling method. Although the rated output power is 200 W, the power can be increased by parallel operation. This product can be optimally used as an interface for standard power supplies used in equipment that handles high voltages, such as power supplies for power conditioners, BMU* power supplies for high-voltage lithium ion batteries and power supplies for high-voltage secondary battery systems.

*BMU: Battery Management Unit
