DC-DC Transformator

A transformer is required which transforms from 1000 V DC down to 48 V DC.

Minimum requirements
- Transform 1000 V DC to 48 V DC.
- 7 kW output in the 48 V DC network (approx. 146 amps)
- Fluctuations in the 48 V DC network: 45 to 55 volts
- Designed for 300 days of use per year and 12 hours of use per day.
- Efficiency > 90 %
- Lighter 3 kg
- Smaller than 300 x 300 x 150 mm
- Communication and discussion with the client as to why something smaller, lighter and better is not possible
- Circuit diagram
- Parts list and component order list
- Estimated price


Desired requirements
- Efficiency > 97 %
- Fluctuations in the 48 V DC grid: 47 to 51 volts
- Lighter than 2 kg
- Smaller than 180 x 180 x 100 mm
- XT90 plug connection
- 10 kW output in the 48 V DC grid (approx. 200 amps)
