Special statement：

1. The technical data are based on natural gas with a calorific value of 10 kWh/Nm³ and a methane no. > 90%

2. The technical data indicated is based on standard conditions according to ISO8528/1, ISO3046/1 and BS5514/1

3. The technical data is measured in standard conditions: Absolute atmospheric pressure：100kPa Ambient temperature：25°C Relative air humidity：30%

4. Rating adaptation at ambient conditions according to DIN ISO 3046/1.The tolerance for the specific fuel consumption is + 5 % at rated output.

5. Dimension and weight above are just for standard  product and may be subject to change. As this document is used only for presale reference, take the specification supplied by Smart Action before ordering as final. The applicable ambient temperature is -30 ° C ~ 50 ° C; when the ambient temperature exceeds 40 ° C, the rated power is reduced by 3% for every 5 ° C increase in temperature. Applicable altitude is less than 3000 meters; when the altitude exceeds 500 meters, the rated power is reduced by 5% for  every 500 meters of height.

[2] The oil standard refers to factors such as local ambient temperature and air pressure.

Alternator compliance withGB755, BS5000, VDE0530, NEMAMG1-22, IED34-1, CSA22.2 and AS1359 standard. 

In case of nominal mains voltage variations by ± 2%, an automatic voltage regulator (AVR) must be used.  

SAC-200 Control system

Programmable control system is adopted with touch screen display , and various functions, including: engine protection and control, paralleling between gensets or gensets and grid, as well as communication functions. etc.

Main advantages

→ Premium gen-set controller for both single and multiple gensets operating in standby or parallel modes.

→ Support of complex applications for power production in data centres, hospitals, banks and also CHP applications.

→ Support of engines both with electronic unit – ECU and mechanical engines.

→ Complete control of the engine, alternator and controlled technology from one unit provides access to all measured data in a coherent and time corresponding way.

→ Wide range of communication interfaces allows smooth integration into local monitoring systems (BMS, etc.)

→ Internal built-in PLC interpreter allows you to configure customised logic to meet demanding customer requirements on your own without extra programming knowledge and in a fast way.

→ Convenient remote control and service  

→ Enhanced stability and safety
