Product Description

TH0460   Coaxial Shunt Multiplexing Unit
TH0460 Coaxial Shunt Multiplexing Unit

 

1. Summary
TH 0460   is a precision and high-efficiency coaxial shunt multiplexing unit device. It adopts ultra-sensitive, high-efficiency, polarization-sealed relay technology, which can well eliminate the influence of the relay itself. The built-in coaxial shunt is very suitable for calibrating multiple AC and DC current ranges.

  2. Working Frequency:   DC  ~ 100 kHz
  3. AC / DC Difference:   ≤ 30 ppm @53 Hz
  4. Optimal Phase Displacement:   5  μ rad
  5. Nominal Output Voltage :  1 V ( customizable)
  6. Support External Voltage Input(Max  ≤ 1.2 V)
  7. Multiple voltage output channels, support Type-N type and banana head two wiring methods .
  8. Ability to withstand instantaneous current shock .
  9. Has greater current carrying capacity.
  10. Built-in buffer to reduce output impedance (1mA, 10mA)
  11. extremely low temperature coefficient, power coefficient, good heat dissipation structure .
 

3. A pplication

Note [1] :The initial deviation refers to the deviation between the measured resistance value and the nominal resistance value after the rated DC current is applied for 10 minutes under the calibration temperature environment;
[ 2] :The initial deviation of the DC resistance has included the power factor influence error under the nominal current. When measuring other non-nominal current values, additional measurement uncertainty should be introduced. The calculation formula is:
