CWT Ultra Mini series

The CWT Ultra-mini has an extremely thin, clip-around Rogowski coil of typically 1.6mm cross-section. Such a thin coil enables currents to be measured in the most difficult to
reach parts of a power electronic converter with negligible disruption to the circuit under test.

Technical data:
Measure range do 6kA
Output signal ± 6V dla prądu max
Bandwidth kilka Hz do 30MHz
Positional accuracy typically ± 2%
Linearity ± 0.05% pełnej skali
Operating temperature range -40°C...+125°C
Supplier operating temperature 0°C...+40°C
Output BNC
