IT8511A+ : โหลดอิเล็กทรอนิกส์กระแสตรง, 150V, 30A, 150W, มาพร้อมฟังก์ชั่นทดสอบแบตเตอรี่, ทดสอบอัตโนมัติ,
ทดสอบ OPP test, ทดสอบ OCP test Single Channel DC Electronic Load IT8500+ series is a single-channel programmable electronic load . With power ranges from 150W to 3000W . The user can perform online voltage measurements and adjustments or simulate short circuit test using the simple keypad on the front panel . It also offers a full - featured battery mode for discharging test . IT8500+ series DC loads are a versatile instrument for static and dynamic testing of power supplies , batteries , DC - DC converters , battery chargers , provides user the best testing solution. Features ▪ Highlight VFD display ▪ Dynamic mode:up to 10kHz ▪ Resoulution of voltage and current: 0.1 mV / 0.1 mA ▪ Four working modes: CV/CC/CR/CP ▪ Remote sensing function ▪ Battery test,automatic test, OPP test, OCP test funcitions. The load will default in the specified mode when turn it on. ▪ Storage for 100 sets ▪ Short-circuit function ▪ Test function ▪ Current monitoring funciton ▪ Power off memory function ▪ With rotary coding switch to make an easy operation ▪ Portable strong case equipped with non-slip feet ▪ Intelligent fans cooling ▪ Built-in Buzzer function Constant Current(CC) In CC mode, the electronic load will sink a constant current regardless of the changes of input voltage. Constant Voltage(CV) In CV mode, the electronic load will attempt to sink enough current to control the source voltage to the programmed value. Constant Resistance(CR) In CR mode, the module will sink a current linearly proportinal to the input voltage in accordance with the progrmmed resistance. Constant Power(CP) In CP mode, the electronic load will dissipate power in accordance with the progammed value. If input voltage increase, input current will decrease. Transient Mode Transient operation enables the module to periodically switch between two load levels, as might be required for testing power supplies . Transient operation can be turned on and off from the front panel ( shift + numeric key”2”) . Before you turn on the operation , you should set the parameters associated with the transient operation. The parameters include: A level, B level, frequency, duty cycle and transient testing modes. There are three different transient testing modes : continuous, pulse, and toggle. Continuous Mode In continuous mode, the electronic load generates a repetitive pulse stream that toggles between two load levels. Load could switch the state between two value settings, A/B. Pulse Mode In pulse mode, the electronic load generates a transient pulse of programmable width when pulse transient operation is in e ffect. Th e load will automatically switch to A level after maintaining A width time. Then it will switch to B level. The load will not switch to A level again until the instrument receives the pulse signal. Toggle Mode In toggle mode, the electronic load will switch between A level and B level when receiving a trigger signal after the transient operation is enabled. The following picture shows the current waveform in toggle transient operation. Automati c Test Function The automatic test function of the IT8500+ series electronic load is useful for simulating various tests and allows the user to edit up to 10 groups of testing files. Each file has 10 steps and up to 100 files can be edited and saved into the EEPROM. User can also set the default power-up mode to be automatic test. It improves the productivity and automatically judge the product quality. List Mode List mode allows you to generate a complex current sequence. Moreover, the mode change can be synchronized with an internal or external singal, to accomplish dynamic and precise test which can save cost for users. Users can edit step value, pulse width and slope sequence and meet a complex test request. A list file includes following parameters: file name step counts (range 2-84), time width of single step (0.00002s-3600s), step value and slope. The edited list file can be recalled easily. The DC load provides 7 nonvolatile regisers to save list files setting for recall later. In the list mode, the DC start to run the list file once receiving a trigger signal, continue to run until end of the operation or receiving another trigger. Remote Sense When working in CC, CV, CP and CR mode, if the electronic load consumes a very large current, it will cause a voltage drop in the leads between the connected device and terminals of the electronic load. In order to ensure testing accuracy, the electronic load provides a pair of remote sensing terminals in the rear panel where users can sense the output terminal voltage of the connected device. Users should set the electronic load in REMOTE SENSE mode before using this function. By eliminating the effect of the voltage drop in the load leads, remote sensing provides greater accuracy by allowing the electronic load to regulate directly at the source's output terminals. Battery Mode A battery test mode is provided that will measure the ampere*hour (A *hr) characteristic of a battery. It measures the time it takes for a battery voltage to drop to a specified value while drawing a constant current from the battery. There are three stop conditions for IT8500+ series loads: Time, capacity and voltage. In addition, user can make any combination of stop conditions to achieve “ An d ”, “ Or ” relationship. When one or more stop conditions are satisfied, the test is ended and the discharging time, capacity in ampere*hours (A*hrs) of the battery is calculated and displayed on the front panel.
