Isolated CONVERTER for LOW VOLTAGE measurement: 0 to 1mV into 0 to 10V

Analog converter, fast and precise, of gain 10000, for very low level signals.

Ideal, in “DC current transducer” mounting, for easy measurement, with very low losses, of currents up to 250A. When mounted as DC current transducer, inputs can be connected (with screw or clamp) directly on the lead portion that drops up to 1mV when supplied with current up to 250A.

This high performance mini-module transmits, at scale 10,000 and within 200 microseconds, “0 to 1mV” applied on its input.

This analog converter was initially intended for the monitoring, on very low resistance shunts (of a few µΩ), of DC currents with rapid fluctuations.

Description

Input: 0 to 1mV ; impedance: 10 kΩ

Output: 0 to 10V, on load ≥ 2 kΩ

Accuracy: better than 0.3%

Regulation: < 5.10-4, with load varying from 2kΩ up to 100kΩ

Ripple: < 100 mV

Response time: ≈ 200 µs (can be increased upon request)

Isolation: triple, with input/output, input/supply and output/supply: 3kV

Power supply voltage: standard, 24V DC ± 10% /  <  40 mA / load 2 kΩ

Possible load: ≥ 2kΩ

Protections:

  • against inverted connections on input and power supply
  • against accidental overvoltage on input: 1V
  • against overloads and short-circuits
  • isolations 3000V
  • against vibrations, and tropicalisation: with moulding
  • sealing iP67, except connections
  • elimination of the faulty-contact risk (no DIL switch)
  • negligible temperature rise (high performance conversion)

Standards: CE ; RoHS ; EN 60905-1

Temperatures:

  • coefficient: < 2.10-4 / °C
  • operation: -20°C to +60°C
  • storage: – 40°C to + 90°C

Three modules:

  • DIN rail mounting (RD)
  • wall mounting with external connector and 2 M3 screws (P)
  • mounting on printed circuit, connecting pins Ø 1mm (CI)

Optional: all-aluminum case
