Product Overview：

Product Features: ​ 

1.The three-phase CNC sine wave inverter delivers output with soft-start and soft-stop functions, ensuring fast testing speed and high accuracy.

2.Testing functions for the transformation ratios, types, and polarities of three-phase transformers, single-phase transformers, PTs, CTs, and Z-type transformers. 

3.The three-phase test features line-to-line voltage ratio, line-to-phase voltage ratio, turn ratio, vector diagram, and group connection testing functions.

4.Features angular difference testing capability during single-phase testing.

5.The tap position range can be tested up to 99 positions.

6.Wide measurement range, up to over 2000.

7.High/Low Voltage Connection Reversal Warning.

8.Output short-circuit alert.

9.CNC constant-current source with DSP-controlled power supply for higher efficiency.

10.Can measure the DC resistance of inductive components in the windings of single-phase and three-phase transformers.

11.Automatic test termination, discharge, and wiring removal prompts.

12.A temperature sensor can be configured to measure the transformer temperature, or it can be entered manually.

13.The clock and date display remain functional when power is off; data is stored locally with 100 test records available for transfer to a computer (PC).

14.Thermal printer printing function.

15.Compact size and lightweight design for easy portability and use.
