General Introduction
The ADG250-4 series 50/60Hz generators are designed for general purpose applications. The products range from 150kVA to 300kVA, with 4 poles and 1500 / 1800rpm operation speed.
All products have been designed in strict accordance with IEC60034, ISO8528, NEMA MAG1 & China national standards. Due to the optimized designs and the strict quality control, the products have the world-class performance and best reliability, suitable for both linear loads and non-linear loads, as well as both static and dynamic loads.
Comparing to other existing products in the industry, the ADG250-4 generators have the distinct technical advantages in the following aspects:
1) The products have the minimum frame size., 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 high quality 50/60Hz 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 kinds of dynamic loads and non-linear loads.
4) The products have the ultra-low full-load temperature rise, which ensures them high operation reliability and long service life.
The ADG250-4 generators can also be connected with 3-phase, 6-phase or 12-phase rectifiers (with 3-phase, 6-phase or 12-phase stator winding designs) to realize the high-quality DC outputs.
