ATS
ATS cabinet is mainly applied to the automatic switch between prime and emergency power, composing an automatic emergency power supply system together with diesel generating sets. It will monitor prime power, When it is cut off, it can automatically switch loads such as emergency illumination, security power and fire fighting equipment to generating sets. Auto start, auto transfer, auto protection, auto power supply
Standard configuration:
Brand: ABB, Schneider, Socome, Suyang, AISIKAI

Parallel distribution cabinet is designed for the parallel running of main power diesel generator sets. The system can operate automatically or be controlled manually.
The system has the functions of automatic frequency detection, synchronizing detection and switch-on.
It is convenient to expand the capacity to satisfy the need of increasing load.
It can be used together with multiple generating sets (32 parallel generating sets max.) to control multiple diesel generating sets for automatic synchronization.
It offers stable frequency and voltage and can bear large-capacity load impact, achieving reliable supply, centralized management and more flexible power allocation.

Load Bank
The purpose of most land banks is used to test of the emergency generator sets, verifying all genset components are in optimal working condition under different loads. Another purpose is working combined with the generator set, to take the load of the generator set is always above 30%
Advantages of Load Bank
Three types of load banks are usually used to genset.
