TI2000 DC High Current Standard Source
1. Summary
TI2000 is a series of DC high current standard sources for industrial detection. It adopts a modular design and can be used as a single source or as a combination of multiple sources to adapt to application scenarios with different current specifications.
2. Features
• Multiple module sources are available: 300 A, 600 A, 1 kA.
• Single current range, no need for relay shifting, high reliability.
• Supports combined output of multiple module sources, up to 10 kA.
• Accuracy: class 0.02 or 0.05.
• The typical value of short-term stability is better than 0.005%/h.
• The unipolar source can be connected to an external commutator (accessory) to achieve current commutation.
• Bipolar source (optional) generates positive and negative currents directly through the circuit.
• The maximum load voltage of constant current output reaches 3.5 V.
• The output ripple coefficient of constant current output is less than 0.5%.
• Communication interface: LAN, RS232.
• Large current rises and falls slowly, reducing current surges, and it can also rise and fall quickly according to needs;
• Optional DC voltmeter to build a DC shunt detection system.
• Optional sensor power supply and output tester are available to build a current sensor detection system.
3. Applications
☆ Calibration of DC shunt |
|
• Supports calibration and testing of DC shunts using the standard source method (an external voltmeter is required). • The maximum load voltage is 3.5 V, which is suitable for testing multiple shunts at the same time in the production line. (Note: The number of simultaneous connections is related to the load size of the shunt being inspected.) • Support docking with the user's automatic test system (or customized software) to achieve automatic testing. • Support the following test: basic error test, error consistency test, error stability test, measurement repeatability test, shunt thermal balance test, overload test, etc. |
☆ Calibration of Current Sensor |
|
• The standard source method is used to calibrate and measure the current sensor. • It is also suitable for the simultaneous detection of multiple current sensors in production lines. (Note: The number of simultaneous access is related to the load size of the sensor being inspected). • Support docking with the user's automated test system (or customized software) to achieve automatic testing. • Supported detection items include: basic accuracy error, zero output error, full-scale output error, linearity error, return difference, repeatability error, zero drift, thermal zero drift (with temperature control box), thermal sensitivity drift (with temperature control box), overload capacity, power influence, the rate of change of load (with load box), etc. |
