中频电源
GMC-IntermediateFrequency Conventionalityl(General Features)
400Hz军用静态变频电源
400Hz Solid State Frequency Converter
品功能与特点:
Features & Advantages:
体积小、重量轻、噪音低:
采用脉宽调变技术(PWM)使体积缩小、重量也相对减轻。
Small, Light & Space Saving:
Typically, 1/4 size of motor-generator sets of the same power output rating.
省安装费:
体积仅传统马达发电机组(中频电源机组)的1/4,节省搬运、运输费用。噪音小,不需另设一空间存放或做隔音处理。免避震工程,节省安装费用。
High Efficiency, Optimum Stability, Superior Heat Dissipation.
Economical Cost of Ownership:
Modular design permits quick and easy replacement. High efficiency features reduce operating costs through 25% and upward utility savings compared to motorgenerator sets.On-site repairs are easily accomplished.Motorgenerator sets quite often must be removed from LOCAIION for repairs, resulting in costly construction charges. Olid State design eliminates the need for a concrete pad for mounting.
模组化设计:
维修简便快速。 【马达发电机组(中频电源机组)一故障,经常得从现场拆卸修护,既浪费金钱又延荡修复时间,欠缺时效性。】
Low Noise:
Solid State frequency converters have no moving mechanical parts generating a loud racket, it can be located close to the equipment they serve. Its low audible noise level eliminates the need for expensive sound insulation.
效率高,稳定度佳,散热效果佳(省电;省能源;省钱):
采用新型绝缘闸双极电晶体(IGBT)组,能推动大工作输出电流,提升品质稳定度,减少电力损耗及干扰。
Low Harmonic Distortion:
Total harmonic distortion at 3% max.
纯净化输出电源品质:
双重电力转换,提供纯净可靠的正弦波电力输出。
Pure Output Power Quality:
Double Conversion. It provides clean and consistent sine wave output.
输出电压10%可调。 两段式输出频率:
400Hz固定频率,300Hz~800Hz可变。(可接受特殊频率订制)
10% Output Voltage Adjustable.
输出电表:
提供四位数之数位电压表、频率表及电流表
暂态反应速度快:
对100%的除载/载入,输出负载稳压率在反应时间1ms以内,便可稳定在±0.5% (线性负载)。
异常保护功能:
具过电流、过电压、过高温、短路保护及告警装置。遇异常状况时,本机的电子线路会自动感应并立即跳脱,同时发出警鸣通知使用者做紧急状况处理。
Abnormal Protection:
Electronic circuits for fast detection and trip off protection for Over current, overvoltage, over temperature,short circuit and Alarm system.
过载能力强:
120%时持续1小时,150%时1分钟,200%时为15秒。【本数据是依据25%工作周期(duty cycle)测试所得】。
Strong Overload Capability:
120% - 1 hour, 150% - 1 minute, 200% - 15 seconds at 25% duty cycle.
Individual Phase Regulation at Output:
Excellent voltage regulation under 100% unbalance load.
三相独立:
可忍受三相不平衡负载。
Output Isolation Transformer,
capable to sustain CEMF (counter-electromotive force).
具输出隔离变压器,可以忍受负载端的反电动势。
符合MIL-STD-704航空电源规范
MIL-STD-704 compliant.
选项:
输入电压36VAC或依顾客要求规格制作。
可接受军用静态变频器和28VDC直流电源供应器一机成型。
Option:
36VAC input voltage or acc. to customer’s specifications.
"Add on module" of Solid State frequency converter and 28VDC power supply.
