PEM Rogowski coil CWT Mini300 mini series current transformer pulse probe 60KA (conductor diameter 3.5 mm)

PEM CWT Mini and MiniHF are produced by the globally renowned Roche current probe brand PEM,

CWT Mini series Roche current coils feature a smaller form factor and nearly zero insertion impedance.

CWT Mini & MiniHF Main features:

• Traceable calibration data (including certificates)

• non-contact measurement has no effect

• on the circuit under test no magnetic material means excellent linearity

• completely isolates DC current, allowing testing of small ripple currents on large DC

currents

• Long-term voltage withstand up to 5kV (2kV withstand for CWT Mini 3.5mm wire diameter)

• Overcurrent range will not cause damage (not exceeding the absolute maximum di/dt)
