High Current Load Tester Specifications
Features:
1). Built-in high-configuration industrial computer, imported 15-inch true color large LCD touch screen operation, no need to connect any auxiliary equipment for testing, fully automatic control, foolproof operation, fast, simple, and convenient:
2). With automatic current stabilization system, equipped with USB, R485, R232 multiple interfaces, easily connect external U disk, printer, and other devices. Can be remotely operated via long-distance transmission.
3). Adopts the latest power electronics technology, imported high-precision sensors, strong anti-interference capability, high output accuracy, up to 0.2 class.
4). Just set the target current, no need for manual monitoring, only need to set the test voltage, current, and step size, eliminating tedious tasks such as manual voltage adjustment, manual recording, and curve drawing, reducing labor intensity and improving work efficiency. After the work is completed, data can be read to the computer for viewing.
5). Equipped with minimum and maximum values for current and temperature, with automatic alarm function when exceeding the limit values. Has reliable self-protection functions such as overcurrent, overvoltage, overheat, and short circuit.
6). Equipped with precision adjustment menu, users can adjust the error value themselves.
7). User-friendly interface, friendly software interface, complete functions, easily complete calibration work, with current and temperature recording and analysis functions, and can store current and temperature waveforms, making it more intuitive to analyze the relationship between current and temperature. All data and test analysis results are clear at a glance.
8). Can display three-phase full current curves, up to 120 temperature curves (according to customer selection). Can be equipped with a micro printer, allowing on-site printing of curve charts and test data at any time.
9). Test modules can be customized according to user requirements, and software is free to upgrade for life.
Precautions:
1. In the current generator control cabinet: connect the output terminal to the input terminals a and x of the current booster; connect the instrument terminal in the control cabinet to the instrument measurement terminal of the current booster.
2. The transformer casing, operation console, and host must be properly grounded.
3. Open the air switch in the cabinet, and the power indicator light will be on. The voltage regulator of the control console automatically adjusts to zero, the zero adjustment indicator light is on, waiting for current boosting. Set the test time (by time setting), current (rotate the current selection switch). Press the start button once, the working indicator light is on, indicating that the current booster has been connected to the control power supply, then press the boost ↑ button to start boosting current.
① The current starts from zero and increases while closely monitoring the indication of the measuring instrument and the condition of the test object.
② This control console is semi-automatic control. After the test time (set by time), open the air switch, first press start then press the boost button to reach the required current. It has functions such as manual boost, buck ↓, automatic timing, and automatic return to zero.
4. Rotate the voltage regulator evenly clockwise, pay attention to the output current indication on the operation console until the required high current is reached. To ensure test accuracy, a standard ammeter can be connected in series at the instrument terminal.
5. During the test, once any abnormal phenomenon is found, immediately cut off the power supply, find out the cause before conducting the test again.
6. After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power supply, and cut off the working power before removing the test wiring to ensure safety.
