Specifications

Power factor

Partner 4-pole alternators are designed to operate between 0.8 and 1 power factor. The alternator will be disqualified when operating below 0.8 power factor.

Assessment

Rating is at sea level and a reduction of 5% - 10% should be allowed if the unit operates at any altitude greater than 1500MASL (consideration should be given to whether the engine is Turbo or naturally aspirated)

VAC

380-400-415V/220-230-240V (50Hz)

• The Silencer is installed within the soundproof cover within a specially manufactured fire compartment.
• The control panel is installed inside the hood and has an ATS assembly

Our AMF control panel uses a deepwater control module

The Module is an automatic network failure controller for generator set applications. The AMF panel is used where the local grid supply is supported by an appropriately sized generator set. The AMF panel monitors local power; If this supply fails or falls outside preset limits, the AMF panel will control preheat, fuel solenoid, and generator set starting through relays and contacts or through the engine ECU, if available.
