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:

  • Control option switch, transfer option switch, emergency stop, buzzer, voltmeter, ammeter, meter, controller, ATS Switch, breaker.
  • Multiple input/output functions can be customized.
  • Standard Capacity: From 20A-3200A


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

  • Confirming the gensets output capabilities as opposed to just starting it up on occasion.
  • Finding problems, instead of when an emergency arises, savings costs and prevents future breakdowns.
  • Helps to avoid wet-stacking and cleans out any carbon deposits.
  • Confirms that the engine cooling system will work efficiently under load.
  • Makes sure that the Genset will work properly when needed.


Three types of load banks are usually used to genset.

  • Resistive
  • Reactive
  • Intelligence
