TKF-12 Phase sequence tester with test declaration WMGBTKF12

The tester is designed to check three-phase power installations in a wide range of phase-to-phase voltages from 100V to 600V
Indication of the presence of voltages of all phases:
- all indications via LEDs (3 indicate the presence of voltages, 2 direction),
- symmetry control of all voltages - lack of voltage in one of the phases is signaled by turning off the appropriate LED,
- indication of the spin direction,
only if all phase conductors are connected and symmetrical voltages,
Internal thermal protection
- self-switching off of a device left under voltage for too long.
Power supply from the measured installation.
