MTP Series High Power DC Power Supply

Overview

The MTP series DC power supplies are High-power Switching power supplies developed by iDealTek-Electronics based on IGBT semiconductor components, adopting AC/DC power processing topology with full-bridge phase-shift soft-switching technology.

The 3KW model is the only one in this series of High-power DC power supplies that adopts single-phase 220Vac input with output power at 3KW with output voltage ranges from 30Vdc to 600Vdc.

It integrates the main control part and IGBT drive part of the power supplies and uses high-quality miniaturized single-phase input semiconductor devices and customized miniaturized heat dissipation to make the 3KW Switching Power Supply into a 19-inch standard 2U rack-mounted chassis for convenient system integration and installation, while ensuring the high-precision, low-ripple and high-efficiency output characteristics of this series of DC power supplies, the power density and dynamic response speed of the 3KW High-power power supply are improved.

Some models of MTP – 3KW DC power supplies still retain the unique 2 times rated current overload capacity (except for high-current output models), which can cope with inductive and mixed load requirements for high-current output at the moment of starting.

At present, this series of high-power DC power supplies are mainly used in the testing of small brushless motors, the power electronics industry, and the electronic device industry.

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.

Key Technology Introduction

Air duct design

Full-sealing independent "Chimney" type air duct design adopted, the inner circuit uses independent cooling fan to improve the product heat dissipation effect, and the air inlet has dustproof measures, which greatly reduces dust and debris entering the power supply. The radiator and fan can be cleaned and maintained separately. 
The heat dissipation system undergoes rigorous simulation and actual testing, and is designed with reliability in consideration of national standards and enterprise standards to ensure that the device with low temperature rise and long life. 

Modular design

The power supply follows the modular design concept and requirements. According to the analysis of product characteristics and functions, each subsystem will use components with independent functions. By the Laminated busbar structure and the use of standardized long-term verified power units, the loop sense is effectively reduced, and the reliability of the product operation is greatly improved. 

Core components

The key and important core devices are all internationally renowned brands, and high-quality devices to ensure the stability and reliability of product operation. 

Installation Environment

l  Ambient temperature: Please have the power source working in safe temperature range (0℃ ~ 45℃) or it would affect life of power source. 

l  Please install the power source at least 50cm distant from surroundings to have better ventilation. 

l  Please install the power source away from vibration (less than 0.6G), especially equipment like puncher. 

l  Keep the power source away from direct sunshine, humidity or place with water globule. 

l  Keep the power source from corrosive, flammable & explosive gas.
