MTP Series Switching DC Power Supply
Overview
MTP series High Power DC power supply is a family of DC switching power supplies with wide output power ranging, high output accuracy, high efficiency and low output ripple performance.
The output power of this series of DC power supplies ranges from 3KW to 2MW, and the output voltage ranges from 30V to 1500V, providing users with a complete product selecting scope.
MTP series of power supplies use full - bridge phase - shift soft - switching technology, which makes this series of DC power supplies have up to 88% working efficiency and 20ms transient response time.
This series of DC power supplies has a two-stage conversion circuit structure and dual closed-loop control circuit system to ensure power supply with high stability and good output accuracy.
All the MTP series power supplies have perfect protection functions, which can ensure long-term & reliable operation of the power supply.
The MTP - 0200 - 0075T is a product with 15KW rated output power in the MTP series power supply family. It uses a 5U 19 - inch standard chassis and is compatible with power instrumentation system integration requirements.
The output voltage ranges from 0 to 200V and the output current ranges from 0A to 75A, which can meet the testing needs of various power electronics industries, electronic equipment industries, new energy motor industries and power battery industries.
