Product Overview

The TA300 from Pico Technology is a 40A AC/DC current probe with 100KHz bandwidth. It is a precision probe for smaller currents, rated for use up to 300V CAT III on uninsulated conductors. Overvoltage Category III covers the equipment making up the electrical installation within a building, including distribution boards, circuit breakers, junction boxes, switches, fixed socket outlets and industrial equipment such as permanently connected stationary motors. The TA300 uses hall effect to measure AC and DC currents. Connect the TA300 to the required channel of the PicoScope 4444 via the D9 connector. The oscilloscope will identify, power and activate the probe automatically. The output zero offset of the probe may change due to thermal shifts and other environmental conditions. Offset is controlled via the PicoScope 6 software.
  • Nominal current is 40A AC peak or DC
  • Resolution is ±1mA
  • Nominal 5V power supply via PicoScope 4444
  • 25mm conductor diameter
  • 2m long screened cable terminated with D9 plug
  • Operating temperature range from 0°C to +50°C
  • Safety standards EN 61010-1, EN 61010-2-032
