Power supply product300-1000VDC input, isolated DC-DC converter TEP200-280
 High voltage and wide input voltage range (300 to 1000 VDC)
 Isolated type Convection cooling method
 Parallel operation for increased power
April 16, 2018
TDK Corporation announces the development of the TDK-Lambda brand of isolated DCDC converter TEP200-280, which supports wide range high voltage inputs from 300 to 1000
VDC. The new product satisfies customers' needs as a step-down converter that converts
high voltage obtained from renewable energy sources into an input voltage for standardpower 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 rangeof high voltage inputs from 300 to 1000 VDC. It converts high voltage obtained fromrenewable energy to 280 VDC, the input voltage for standard power supply for generalindustrial devices. As the output voltage (280 VDC) is a general input voltage for ourstandard 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 equipmentthat 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-----Main applications
 Interface Power supply for general high-voltage devices, 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
Main features and benefits
 High-voltage and wide input voltage range (300 to 1000 VDC)
 Output voltage (280 VDC) is the general input voltage for standard power supplies
 Isolated type Convection cooling method
 Parallel operation for increased power Board coating and plastic cover are equipped as standard
