All-in-one three-phase relay test set for field work
The AK-6 is a three-phase relay test set with AC and DC voltage, high-power current burden and AC/DC auxiliary supplies, in an all-in-one Windows CE design that runs its five test modules without a laptop.
Advantages
Field testing without a laptop
An all-in-one design with built-in Windows CE, a 6.4-inch TFT display, panel keyboard and rotary encoder runs the five test modules — DC, AC, distance, harmonic and frequency — on its own.
High power, high accuracy
The unit provides 4×300 V (4×110 VA at 0-300 V) and 3×35 A (3×450 VA at 0-35 A) for medium-voltage tests, with a guaranteed accuracy of 0.07 % of reading plus 0.03 % of range at 0-130 V.
Full signal control
Amplitude, frequency and phase are independently and continuously adjustable, with a frequency range up to 1000 Hz and 0.001 Hz resolution.
Protected and reliable
Complete self-protection and alarms cover wrong wiring, open or short circuit, overheating and overload.
Built for the field
A compact, lightweight case can be placed vertically to save space, with RJ45 and USB ports for firmware updates and data transfer.
Applications
- Testing of protection relays at medium-voltage level.
- Distance, harmonic and frequency protection testing.
- DC and AC injection with time measurement.
- On-site commissioning and periodic maintenance.
About the product
The AK-6 combines high burden with a compact, lightweight case, an integrated 6.4-inch TFT display, panel keyboard and rotary encoder for full control without a PC, and RJ45 and USB ports for updates and data transfer; it can be placed vertically where bench space is limited.

Frequently asked questions
Does it need a PC?
No. It has a built-in Windows CE system with a 6.4-inch TFT display, panel keyboard and rotary encoder, so it runs standalone.
What test modules does it have?
Five: DC test, AC test, distance test, harmonic test and frequency protection.
How much can it inject?
4×300 V (4×110 VA at 0-300 V) and 3×35 A (3×450 VA at 0-35 A) for medium-voltage level tests.
Can it be used vertically?
Yes. The compact, lightweight case can be placed vertically to save space on site.
How are results transferred?
Through the RJ45 Ethernet and USB ports, which also handle firmware updates.
