AC current source

  • Product No:CC11
  • Manufacturer:Calmet Ltd.

Current source (phantom load) type Calmet CC11 together with electricity meter tester (type Caltest, Calport and other) is dedicated to test all types of single and three phase electricity meters. Function of load current change enables to test electricity meters on site independent from actual load. Current source can be also used to test devices such as: ammeters, RCD leakage circuit breakers, current transformers, clamps and clamp meters using additional coils.

The CC11 is single phase AC current source in range up to 5A accuracy class 0.2 with signal frequency equal to 50/60Hz like the supply voltage frequency and with phase shift 0° or 180° relative to the supply voltage.

The CC11 enables:

  • rough and fine increasing and decreasing of current without necessity to disconnect tested meter and end user from circuit,

  • digital measurement of current injected in current circuit of meter,

  • rough and fine setting and measurement of current in current circuit of tested devices such as: ammeters, current transformers and other.

Features:

  • Loading of single and three phase electricity meters

  • Current setting range from 0.005 to 5.000A

  • Digital measurement of output current

  • Silent operation and no heating

  • No need to disconnect meter and end user from circuit during electricity meter testing on site

  • Powering directly from measurement circuit

  • Galvanically isolated output

  • Accuracy class 0.2 for testing of AC current devices
