The Revolutionary High-power, High-precision, Multi-functional, Mini relay tester
KFA310 has been designed with a compact interior, similar in size to an iPad, Powered by batteries. It weighs only 3.7 kg and offers 4x300V and 3x20A outputs, Its maximum current can reach 50A, the output power reaches 130VA.
It focus to Maintenance and Testing of Distribution and Medium-Low Voltage Protection Devices in Non-Electrified Environments.
Description
1. The world's smallest relay tester with 7.0-inch LED touch screen,, easy to carry in a iPad size, 3.7kg, high current up to 50A, high precision, can continuously output with 3x10A conditions.
2. Extremely simple design for its internal structure, ensure high quality and reliability.
3. Innovative “Plug and Play” technology enable 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: 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. High precision output, can be used as a standard source.
Key Points
Innovative“Plug and Play ”After-sales Service Advantages:
▪ Simple structure, beginners can achieve independent installation.
▪ Reduced after-sales costs.
▪ Shortened after-sales time.
▪ Goal: Complete after-sales within 20 working days.
The KFA310 handheld mini relay tester, which utilize innovative technology, module design, and a simple internal structure, ensuring a higher level of product quality and providing assurance for a three-year warranty commitment. Besides, it also contributes to achieving the quality objective of a 15-year product service life.For after-sales maintenance, only module replacement is required, and there is no need for accuracy calibration after module replacement. Once assembly is complete, it can be used directly, truly achieving "Plug and Play".
Public disclosure, the internal structure is visualized as shown in the following diagram:
