Kingtech Electrical Co., Ltd.   

Product introduction overview of MK-80 series DC power supply is intelligent, modular of a new generation of high frequency switching DC power supply, is the foundation of our company in the development and production of DC power supply for many years of experience, the new product of careful development combined with the latest technology, the. The product is suitable for middle and small power plants, substations, substation as enterprises, closing the DC operation power supply of high voltage circuit breaker, as well as the relay protection, control signal and emergency lighting uninterrupted DC power supply. The company development and production of DC power supply has twenty years of history, has accumulated rich experience, marketing products throughout the country and exported to Asia, Europe and other countries and regions, enjoy a good reputation. This series product has obtained ISO9001:2008 quality management system certification, so in the product design, development, production process, external parts inspection, product inspection and after sale service, in strict accordance with the quality management system standards. Product design reasonable, reliable quality, convenient use and maintenance, welcomed by the majority of customers. DC power supply products of the company's standard configuration (basic configuration) can meet the user's normal use, and options can be configured to meet the special requirements of users. The basic configuration of the product configuration and features of MK80 series of high frequency switching DC power supply by the charging module and monitoring device; MOS series charging module using MOS soft switching technique is advanced, for 220V DC system, a charging module were superior in the efficiency and reliability of the traditional. It has the advantages of small volume, high switching frequency and input power factor high, all the output characteristics of parallel flow and is equipped with high reliability, at the same time with a variety of automatic protection function. Modules can be charged access or exit, convenient use and maintenance. IGBT series of charging module uses the model of large capacity IGBT power devices, and use the PWM pulse width modulation technology is advanced, has the features of high power output. The serial charging module provides 110V and 220V output for the user to choose. A single IGBT charging module can provide up to 40A of output current, support multi machine parallel, general double charging module in parallel can satisfy most users requirements. IGBT charging module adopts a unique structure, so that the charging current and control bus load changes, at the same time on small capacity battery can achieve stable constant current charging, not overcharge or less charge. Has a voltage and current stabilizing precision and good, to ensure safe use of electricity and prolonging the service life of the battery. Modules can be charged access or exit, convenient use and maintenance. Performance parameters of altitude: not more than 1000 meters (1000 meters above, need expansion) environment temperature: -20 to +50 DEG C relative humidity is less than or equal to 95% (no condensation) indoor use, good ventilation. The operation place no explosive and inflammable dangerous, no gas is enough to destroy the insulation and corrosion of metal, no conductive dust. Installation place no violent vibration and impact. 产品主要技术参数 输入电压：三相四线制AC380V±20% 频率：50Hz±10% 功率因数: ≥0.9 输入过压告警: AC418～456V 输入欠压告警: AC323～342V 输出电压：198～286V（220V系列）；99～143V（110V系列） 浮充电压: DC243±3V（220V系列）；DC122±2V（110V系列） 均充电压: DC254±3V（220V系列）；DC127±2V（110V系列） 稳压精度：≤±0.5% 稳流精度：≤±0.5% 纹波电压：≤0.1% 均流不平衡度:≤5% 输出过压保护: DC231～242V（220V系列）；DC116～121V（110V系列） 输出欠压保护: DC198V～209V（220V系列）；DC99～104V（110V系列） 效率: ≥90% 绝缘电阻: 10MΩ 绝缘耐压: ≥2kVA 噪声: ≤45dB注意事项1.若使用大电流合闸机构且要考虑铅酸免维护电池瞬时放电电流时，一般请按电池容量的2倍计算（视不同厂家电池而略有不同）。 2 in the maintenance free lead-acid battery capacity under normal load current, if the accident is 0.6 times the capacity of the battery, can maintain about 1 hours; if the accident load current is 0.2 times the capacity of the battery, can maintain about 4 hours. The 3 series MK-80 DC power supply under normal circumstances, charging and control bus load is provided by the charging module (two way alternating power outages, by the battery to the control bus load power supply), so please selection gives control bus often load current value, we will with the charging current value into account, choose charging module capacity and the appropriate number of charging module. Other descriptions of various matters to inquire, welcome. The transaction that matters to inquire, welcome.
