Check phase sequence
The ergonomic phase sequence tester Sonel TKF-12L is a proven measuring tool, whose main task is to control 3-phase electrical installations. Phase sequence tester signals compatible or opposite connection. The instrument is suitable for a wide range of phase-to-phase voltages (operating range is from 35 to 690 V, frequency from 10 to 70 Hz) in distribution circuits. The device signals compatible or opposite connections in the electrical installation and, in addition, indicates the symmetry of voltages in each phase. Sonel TKF-12L is characterised by a simple and ergonomic design. Enclosed in a robust and sealed IP 42 casing, the tester ensures high durability and resistance to damage. The measuring instrument guarantees efficient operation in a wide temperature range from -10°C to +45°C. Double insulation according to EN 61010-1 ensures a high level of safety during testing.
- indication of phase sequence in networks with voltage 35...690 V AC
- operation in networks with 10...70 Hz frequency
- voltage indication light
- wired indication of motor rotation
The unique TKF-12L tester is designed to control 3-phase electrical installations in a wide range of phase-to-phase voltages (35… 690 V, frequency up to 70 Hz) in distribution circuits. The indication of the rotating field and the direction of motor shaft rotation is performed.
Aplication of TKF-12L
Measure easily and accurately 16-, 32- and 63-amps industrial sockets with optional AGT-16, AGT-32 and AGT-63 adapters.
Standard accessories, included in the kits, allow for quick verification whether the shaft rotates in the correct direction after the motor is connected. Otherwise, the engine or the equipment driven by it may be damaged.
Intuitive, trouble-free connection
Various colored cables, crocodile clips and test probes allow you to connect the device to the tested object - quickly and without any problems.
Thanks to the innovative technology in the TKF-12L, we have achieved a record range of nominal phase-to-phase voltages: indication of voltage presence is displayed from 29 V AC.
