Specifications

Power factor

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

Assessment

Rating is at sea level and a 5% - 10% derating must be allowed if the unit operates at any altitude above 1500MASL (must consider whether the engine is Turbo or Naturally Aspirated)

VAC

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

Prime Power (PRP)

Sound Attenuating Canopy - SAT

• The sound-attenuating canopy produced by plasma and CNC towers not only meets the requirements of residential sound control, but also ensures the correct cooling aeration required for normal operation. Generator sets can be installed outdoors to save space.
• Modular design for ease of maintenance and access.
• Special high temperature flame retardant sound insulation foam.
• Door hinge and handle.
• Mild steel plate with powder coated surface finish is used for the construction of the upper cover.
• Soundproofing foam ranges from 40mm to 100mm depending on the degree of attenuation required.
• Standard attenuation noise level: 75~80dB within 1m; 72~75dB within 7m.
• The Silencer is installed inside the soundproof cover within a specially manufactured fire compartment.
• The control panel is installed inside the cowl and has an ATS mounted assembly

Our AMF control panel uses a deep water control module

The Module is an automatic mains failure controller for generator set applications. The AMF panel is used where the local mains supply is backed up by an appropriately sized generator set. The AMF panel monitors the local supply; if this supply fails or falls outside pre-set limits, the AMF panel controls the preheat, fuel solenoid and generator set starting via relays and contacts or via the engine ECU if available.
