  • PEM Rogowski coil CWT Mini3 mini series current transformer pulse probe 600 A (conductor diameter 3.5 mm)

PEM Rogowski coil CWT Mini3 mini series current transformer pulse probe 600 A (conductor diameter 3.5 mm)

Brand: PEM

Origin: UK

Mini coil series, up to 20 MHz, conductor diameter 3.5 mm, withstand voltage 2 kV/5 kV optional
Overview

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 performance parameters:

  • peak current: 30A - 30kA peak current

  • output: ±6.0V (full scale)

  • bandwidth (3dB): 30MHz

  • accuracy (typical): up to ±0.2% at the center position

  • of the coil
  • operating temperature range: 0°C to +40°C (integrator);

                        –40°C to +125°C (CWT MiniHF coil);
                       –20°C to +100°C (CWT Mini coil).

  • coil length: 100 or 200mm (customizable length

  • ).
  • coil insulation: 2kV peak (3.5mm wire diameter); 5kV peak (4.5mm wire diameter)

  • lead length: 1m, 2.5m, or 4m (customizable length

  • ).
  •  Power supply: AA battery, 12V DC power adapter

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)
