KDHG-A is a multifunctional CT/PT analyzer featuring MBC power control technology with single AC220V input for both control and power circuits. It automatically performs excitation tests, displays the volt-ampere characteristic curves, and calculates inflection point values without manual step setting. The unit outputs pure sine wave (50-60Hz) up to 1000V, stores 1000 test records, and supports USB data export and on-site printing in a portable design.

1. Safe and reliable: MBC power control technology with single AC220V input for both control and power circuits (eliminates safety risks of separate 380V inputs);
2. Compliant with maintenance standards: pure sine wave output (50-60Hz) with reliable voltage and current values;
3. High output capacity: 0-1000V from single 220V input, ideal for field use;
4. Comprehensive functions: CT/PT excitation, ratio, polarity, 5%/10% error curves, primary current injection, and demagnetizati;
5. Simple wiring: single power input port for safe and easy field connections;
6. Wide test range without external boosters or current generators;
7. Fast thermal printing: automatically selects typical data for on-site comparison;
8. Large FLASH storage: saves 1000 test sets with non-volatile memory;
9. USB interface for U disk data storage;
10. Compact and lightweight for easy portability.
