Product Description

1. Summary
The TH0500 Precision Current Transformers based on the principle of the current comparator, it can produce an output current or voltage that varies directly with the input current from 0.1A to 20 kA. By the connection of a reference shunt burden on the output terminal when outputting an current or directly measuring the voltage when outputting an voltage the primary current can be deduced from the measured voltage .2. Features
(1)Supports two current access modes, through core and direct connected type respectively.
Direct connected type with the input current of 0.1 A…200 AThrough core type with the input current of 500 A…20 kA
(2)Secondary output signal is optional for current (I / I) or voltage (I/ V)
I/I:Optimum uncertainty of 0.2ppmI/V:Optimum uncertainty of 10 ppm
(3)Optional digital display function, support for digital signal output
3. Applications
(1)Establish DC / AC current precision measurement system
(2)Calibrate the DC / AC current source or ammeter
(3)Calibrate the DC current ratio standard (current comparator)
(4)Calibrate the DC current transformer / sensor
(5)Calibrate the DC current I/V transformers
