Ultra-mini AC Current Probe

28 May 2013 - Power Electronic Measurements Ltd. has made significant improvements to its CWT Ultra-mini AC Current Probe whilst maintaining its small form factor that allows it to be easily fitted between the legs of a TO-220 device. 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.

The probe now boasts:

• Extended temperature range from -40°C to +125°C.
• Increased Bandwidth: up to 30MHz (-3dB)
• Improved peak di/dt up to 80kA/µs

The probe will be available from late August 2013.
