1. Kingsine KFA310 protection relay testing equipment marks the world’s smallest protection relay tester with 7.0-inch LED touch screen. Easy to carry, iPad-sized, and weighing only 3.7 kg, it outputs up to 50A with high precision and can continuously output 3x10A conditions.

2. Extremely simple design for its internal structure, ensures high quality and reliability.

3. Innovative “Plug and Play” technology enables this mini handheld secondary injection test set to make after-sales service very easy and efficient, within 20 working days.

4. Main functions

▪ AC/DC test, Ramping, State Sequence, Harmonic, Distance, Overcurrent

▪ Oscillate Test: This secondary injection test set can be used for customizing superimposed oscillation waveform simulation testing.

▪ Frequency test (df/dt, ROCOF)

▪ 3-Phase standard Power source

▪ Energy meter calibration

▪ Double-device synchronous test (up to 6 current channels for differential test)

▪ 8 Channels Low-Level outputs (0 – 8Vrms)

5. With its high-precision output, this mini handheld secondary injection test set can be used as a standard source.
