200KW Robust High Power AC DC Power Supply

MTP Series High Power DC Power Supply

Overview

When the output power of the DC power supplies exceeds 100KW, the MTP High Power DC power supplies do not use the popular multi-module paralleling technology, but still insists on using the all-in-one solution to make high-power DC power supplies. We believe that the reliability of high-power AC DC power supplies is the first issue. Although the multi-module parallel system is flexible for operation, when multiple modules are running at the same time to give full-load and high-power DC output, the control balance of multi-power module units cannot achieve 100% complete balance and coordination, especially under high-power DC output. when there is a sudden change with the input or load that requires the power supplies to respond quickly, the integrated DC power supplies design has better stress resistance and better reliability than parallel solution. 

The 120KW ~ 200KW output MTP high-power AC/DC power supplies are made in a 1300*2100*800 double-door industrial-grade cabinet, with casters at the bottom, or floor-standing cabinets without casters, the output voltage ranges from 120Vdc to 1000Vdc. 
The power supplies can be accessed from the front door to facilitate the installation, wiring and maintenance of the power supplies., adopts a 7-inch LCD touch screen for power supplies’ control programming and status monitoring, and also comes with the standard RS485 communication interface following the MODBUS-RTU international protocol makes remote control and monitoring of the power supplies easy and convenient.

The same standard configuration voltage compensation and short-time 2 times rated current overload functions are equipped (except for some large current output models), a discharging unit or reverse cut-off function can also be added. 

At present, this series of high-power DC switching power supplies are mainly used in battery charging testing, DC motor testing, photovoltaic inverter testing, and various cutting-edge applications that require high-power DC output.

Principle Introduction

This series of High-power AC - DC power supplies are equipped with a reliable two-stage conversion mechanism drive logic circuit and a fast control loop optimized by iDealTek-Electronics. Which balances the requirements of low output ripple and fast DC output response speed, making this series of High-power switching power supplies can provide high-precision, low ripple, high-stability and High-power DC output with fast response speed feature of the switching power supply. All MTP series DC power supplies are equipped with a short-term 2 times rated current overload capacity (Except for some high-current output models) to cope with the inductive and mixed load's demand for high-current output at the moment of starting.
