Product Description TD2010 DC high Current Standard Source *Reference only.1. SummaryTD2010 is a set of DC high current standard source equipment, using modular design, multiple current output units in parallel can directly generate a maximum of 15 kA of high-precision DC high current. The device has high accuracy, good stability, high reliability, and supports continuous 24 hours of work. It also supports optional sensor test work to form a DC current sensor test system, can also be equipped with a special bracket and secondary voltage measurement module, easy to access DC shunt for testing. 2. FeaturesSupport multiple module source superposition output, current output up to 15 kA; Accuracy: class 0.01, class 0.02, class 0.05 Typical peak stability is 15 ppm/h and variance stability is 6 ppm/h; Built-in precision DC voltmeter, no need to attach a digital multimeter for voltage measurement; 24-hour work RS232 interface 3. Applications☆ Detection of DC shuntSupports standard source method calibration and testing of DC shunts. Built-in precision DC voltmeter to measure the output voltage value of the shunt. Support docking with the user's automated test system (or customized software) to achieve automatic testing. ☆ Detect current sensorThe standard source method is used to calibrate and measure the current sensor. The user can choose the sensor test fixture to measure the power supply and secondary signal of the sensor. Support docking with the user's automated test system (or customized software) to achieve automatic testing. 4. Characteristics☆ High stability 24-hour stability typical: 0.003 % (class 0.01), 0.005 % (class 0.02). It can effectively ensure good repeatability and consistency of sensor and shunt detection. ☆ Low ripple contentThe current ripple content of the instrument is less than 0.5 %, which can effectively reduce noise interference and ensure the accuracy of test results and avoids surge voltage or current caused by strong ripple to ensure the safety of equipment operation. ☆ Module source combination outputThe instrument supports DC high-current output in combination mode of multiple module sources, up to 15 kA; The instrument supports adjusting multiple source outputs, improving the current sharing coefficient, and ensuring stability and accuracy under high-current output. 5.
