General Introduction

 

the ADZ280-26 series 400Hz generators are specially designed for aviation applications. the products range from 90kVA to 250kVA, with the 26 poles and 1846rpm operation speed.

All products have been designed in strict accordance with IEC60034, ISO8528, MIL-STD-704F & China military standards GJB1213-91, as well as other international and domestic standards. Due to the optimized designs and the strict quality control, the products have the first-rank performance and best reliability, suitable for both linear loads and non-linear loads.

Comparing to other existing products in the industry, the ADZ280-26 generators have the distinct technical advantages in the following aspects:

1) the products have the minimum frame no., dimensions and weight among the same rating products in the industry.

2) the products have the best voltage waveform with the minimum harmonic distortion; therefore they provide the clean 400Hz power supply to the load to ensure the best operation status.

3) the products have the best performance in both steady state and transient state, which makes them the ideal power supply for all dynamic loads and non-linear loads.

4) the products have the minimum full load temperature rise, which ensures them high operation reliability and long service life.
