KPM KFA320

KPM KFA320
World's Smallest Protection Relay Tester
Portable. Precise. Powerful. Engineered for the field.
IEC61850 ReadyBattery Powered3.8 kg
iPad-Sized. Substation-Ready.
The KPM KFA320 redefines portability without sacrificing performance. At just 3.8 kg and the footprint of an iPad, it fits in a standard carry-on — yet delivers full relay testing capability in the field.
10.1" LED Touch Screen
High-resolution display for clear on-site readings
3.8 kg Total Weight
Lightweight design for single-person field deployment
Replaceable Batteries
2 × 47.52 Wh for extended field operation
Output Power & Precision
Class 0.05 High Precision
The KFA320 delivers Class 0.05 accuracy, qualifying it for use as a standard reference source in calibration workflows. With 4×300V voltage outputs and 6×20A current outputs, it handles complex multi-phase testing scenarios. Peak current reaches 60A, with continuous output capability at 3×10A and 200 VA/phase output power.
No external calibration required after module replacement — true Plug and Play accuracy.
IEC 61850 & Digital Substation Ready
Full support for modern digital substation protocols — SMV, GOOSE, and synchronized end-to-end testing.
SMV & GOOSE Simulation
3×100 + 1×1000 Mbit fiber ports for IEC61850 Sampled Values and GOOSE messaging
Synchronized Testing
Built-in GPS, IRIG-B, and IEEE-1588 for precise end-to-end synchronized test execution
LPIT & Transducer Support
Low-level output, LPIT simulation, energy meter testing, and transducer calibration built in
Software & Test Management
KRT Test Management Suite
The fully-featured KRT software streamlines every stage of the testing workflow:
Graphical test modules with template organization for rapid setup
Auto result assessment and report generation
Xrio/Rio import/export for seamless test file compatibility
Transient playback up to 3 kHz for dynamic fault simulation
Free software upgrades included for the product lifetime
Built-In Safety & Reliability
Anti-Clipping Detection
Real-time monitoring prevents signal distortion during high-output tests
Wrong Wiring Alarm
Automatic detection of incorrect connections before test execution
Overload & Overheat Protection
Self-protecting circuitry ensures safe operation under demanding field conditions
Binary I/O Flexibility
4 binary inputs (dry contacts or 9–300V potential); 2 fast + 2 relay binary outputs
Innovative Plug & Play Architecture
The KFA320's internal structure is intentionally simplified — enabling module-level replacement without specialized tools or calibration. After assembly, the unit is ready for immediate use.
