- summary: The Testec TT-CC 550 is a precision AC/DC current probe designed for oscilloscopes and digital multimeters (DMMs), offering dual measurement ranges (5 A at 0.2 V/A and 50 A at 0.02 V/A) with a bandwidth of DC to 500 kHz. Part of the TT-CC series, which includes models like the TT-CC-220 (300 kHz) and TT-CC-990 (1.5 MHz), the 550 variant balances performance for mid-frequency applications such as motor drives, power electronics, and switching circuits.
Engineered for safety, it meets CAT II 600 V / CAT III 300 V standards, making it suitable for industrial and building installation measurements. Its hybrid Hall effect and current transformer design ensures ±3% DC accuracy, enabling precise tracking of both steady-state and transient currents. The probe includes a BNC-to-banana plug adapter for compatibility with DMMs and features an overload indicator to prevent damage during high-current events.
Powered by a 9 V battery or the included AC adapter, the TT-CC 550 eliminates downtime in prolonged testing scenarios. For engineers requiring higher bandwidths, consider the TT-CC-770 (1 MHz) or TT-CC-990 (1.5 MHz). Compact and rugged, this probe is ideal for troubleshooting inverters, SMPS, and embedded systems where accuracy and safety are non-negotiable.
