Ngi N6900 120V 300A 3000W Programmable Eload DC Electronic Load

NGI N6900 120V 300A 3000W Programmable Eload DC Electronic LoadN6900 Series Distributed High Power DC Electronic Load Product IntroductionN6900 series is developed based on NGI's years of experience in testing for power supply, battery, generator and supercapacitor. It is with high accuracy, high reliability and high cost performance.According to the features of high voltage & power DC electronic loads with complex structures, harsh operating environments, high reliability requirements, and inconvenient maintenance, NGI has made a number of optimization based on the international advanced technology.Application Fields1.Generator2.Charging station3.Industrial/server power supply4.Communication power supply5.Battery pack6.Capacitor module7.High current relay8.Energy storage systemMain Features*Power range: 1-50kW*Voltage range: 120V/600V/1000V/1200V, customization available*Multiple protection: OCP, OVP, OTP, OPP and reverse polarity warning*Comprehensive MOS protection to avoid blow-up*Operation modes: CC/CV/CR/CP*Charging & discharging control function, convenient for battery and super capacitor test*Built-in DCIR test function(Optional)*Easy power expansion by increasing power modules*Analog programming interface(APG), current monitoring interface, and remote/local trigger function*CR/CP function supported by hardware*Short-circuit simulation*Transient over-power loading capability*High power density, minimizing space occupation*Convenient OCP test*Dynamic mode up to 20kHz, editable rise and fall slew rate*Editable Von/Voff, reducing test accidents*LCD screen for data display Intelligent fan control*Built-in auto test function*Standard 19-inch 3U, available for rack installation*Distributed design and flexible power modules*Multiple communication interfaces: LAN/CAN/RS232/GPIB(optional)High reliability designN6900 series has a comprehensive MOS protection circuit. No matter how much MOS is damaged, it will not cause short-circuit between the positive and negative polarity or the positive polarity and the control circuit. The damage of some MOSs does not accelerate the damage of others, which can be used continuously.By distributed design, it is easy to replace or add power modules and is convenient for maintenance and power expansion.N6900 is designed with power limit circuit and has fast response, which can prevent the load from being damaged due to over power.N6900 adopts shielding technology, which has wide adaptability to harsh test environment, and improves the anti-interference ability.Short-circuit simulationN6900 series supports two modes for short circuit: manual and lock.Manual: N6900 will be short-circuited when Short button is pressed. It will stop short-circuiting when button is released. Manual mode is suitable for debugging or R&D, avoiding measurement accidents due to misoperation.Lock: N6900 will keep short-circuiting when Short button is pressed. It will stop short-circuiting when the button is pressed again. Lock mode is suitable for long-time short-circuit test.Auto test functionThe auto test can be used to simulate waveform. This function can improve the test efficiency and can be achieved by SEQ function on the menu. Up to 100 sequence files editing is supported. Each file can support 50 steps.OCP( over current protection) testDuring OCP test, N6900 will load under CC mode and check whether the DUT voltage is lower than cut-off voltage. If lower, N6900 will record the present loading current as the test result and shut the input to stop the test. If the DUT voltage is higher than cut-off voltage, N6900 will increase the loading current until the DUT voltage is lower than cut-off voltage or it reaches the Max. loading current.Remote sense to improve measurement accuracyRemote sense is also know as four-wire sense. When N6900 is working, it will cause a voltage drop in the leads between the DUT and terminals of N6900, which will affect the voltage measurement accuracy of the load.When working under CV, CR and CP modes, to ensure accurate measurement, it is recommended to use remote sense. During remote sensing, terminals S+ and S- are directly connected to the output of the DUT, eliminating the voltage drop in the leads.Charge& discharge testUsers can set different conditions on the front panel to meet their test demands. For example, when battery voltage is lower than initial voltage, N6900 internal counter will start counting. The counter will stop working until the battery voltage drops to cut-off voltage.Exhibitions    For more specifications, please contact us.
