This generator is designed for operations where uptime is non-negotiable, offering the horsepower and electrical output needed to keep large facilities running through extended outages. Its rugged construction and advanced control system make it a dependable choice for mission critical standby power.

Engine Performance and Fuel Efficiency

The MTU 12V 2000 G45 TD engine runs at a consistent 1800 rpm and produces a gross output of 781 bhp at standby, with a net output of 738 bhp after fan power is accounted for. The ADEC electronic governor works alongside full ECU and CANBus implementation to manage engine control and protection with precision. 

Fuel consumption scales predictably with load, measuring 144.9 gallons per hour at 75% power and 98.4 gallons per hour at 50% power. This efficiency profile helps operators plan fuel logistics accurately during long duration outages or scheduled load testing.

ACBCMU700S-60T2F Alternator and Electrical System

The CGT Stamford HCI 634G alternator is directly coupled to the engine in a single bearing arrangement, which reduces wear points and simplifies long term maintenance. It features a 3-phase, 4-pole winding 311 configuration and is separately excited by a permanent magnet generator, giving it strong motor starting capability and stable output under transient loads. 

An MX 321 AVR maintains voltage regulation within plus or minus 0.5 percent, tighter than many comparable units in this power class. The 24V electrical system supports reliable cold starting even in demanding environments.

Control System and Monitoring

Standard on the ACBCMU700S-60T2F is the BC 7310 Digital Auto Start system, based on the Deep Sea Electronics DSE7310 controller. It provides manual and automatic remote start with LCD digital displays for coolant temperature, oil pressure, oil temperature, engine hours, and battery charge status. 

The system includes under and over voltage protection, over current protection, and full readouts for frequency, kW, kVA, and power factor. Full RS485 telemetry support allows for remote monitoring, while an automatic cool down timer protects the engine after load is removed. Operators needing synchronisation or automatic mains failure functionality can upgrade to the BC 7320, BC 8610, or BC 8620 control systems.

Construction and Site Considerations

Built on a fully welded steel baseframe with integrated lifting and jacking points, the unit rides on heavy duty rubber anti-vibration mountings to minimize noise and mechanical stress during operation. The open set configuration measures 175 inches long, 67 inches wide, and 83 inches tall, making site planning straightforward for most industrial installations.

Reliable Standby Power for Demanding Facilities

Complete with a factory test certificate and full operation and maintenance documentation, the ACBCMU700S-60T2F delivers the scale and reliability that large industrial and commercial sites require from their backup power infrastructure.
