Highlights of The Mini Universal Relay Tester KFA320: Minimalist Design, Maximum Performance

Based on the R&D philosophy of "full functional coverage, handheld lightweight design, and no external power required," KINGSINE adopts an innovative software-defined hardware architecture to proudly present the next-generation handheld digital-analog integrated protection relay tester - KFA320.

Full-Function Software Modules

• Built-in 20+ professional test modules covering "simulation-testing-verification" demands, including:

- Overcurrent/zero-sequence section, multi-zone distance protection simulation

- Millisecond-precision differential protection testing

- Complex logic verification (e.g., underfrequency/undervoltage load shedding)

- General modules (e.g., state sequence, synchrocheck tests)

- Setting verification (e.g., power frequency variation, overcurrent with voltage restraint)

- IEC61850 digital testing (GOOSE tripping, SV sampling synchronization test)

• Operates offline or via PC software for remote control

• One-click import of test templates (Schneider, ABB, Siemens, etc.) and report export

Handheld Portability & Lightweight Design

• Total weight: 3.8kg (includes high-capacity battery)

• Compact dimensions: 288×185×95mm with a 10.1" HD touchscreen

• Ergonomic design with anti-slip rubber edges for easy one-handed operation

No External Power Required

• 26.4Ah battery supports 6×20A continuous output per full charge

• 1×350V adjustable auxiliary DC source (0.15A continuous / 0.5A transient for 200ms)

• 100W PD/QC fast charging (Type-C): 10-minute charge for a standard test cycle

All-Scenario Applicability

• Smart substations: Closed-loop protection testing, MU synchronization verification

• Renewable energy plants: LVRT, negative-sequence voltage protection

• Rail transit protection systems: AC/DC hybrid simulation, high-harmonic conditions, fast fault clearance

• Industrial power systems: Motor protection testing, transformer differential protection verification
