Standby and Continuous Power Ratings
The GDW35P/FNE generator set offers an emergency standby power (ESP) of 33 kVA and 26.4 kW, designed for up to 200 hours per year during power outages, with an average output limited to 70% of this rating over 24 hours. Its prime power (PRP) rating stands at 30 kVA and 24 kW for continuous operation under variable loads with unlimited annual hours, also adhering to the 70% average output cap, operating at 400/230 volts, 50 Hz, three phases, and a power factor of 0.8.
Engine Mechanics and Cooling
Equipped with a Perkins 1103A-33G engine, the unit runs at 1500 rpm with water cooling and natural aspiration controlled by a mechanical speed governor. It includes three in-line cylinders displacing 3300 cm³, delivering gross engine powers of 31 kWm in ESP mode and 28.2 kWm in PRP mode, supported by 8.3 liters of oil capacity with maximum lube oil consumption at 0.15% of fuel, and 10.2 liters of coolant.
Alternator Design and Efficiency
The Mecc Alte ECP28 VL4 C alternator features brushless operation with four poles and series star winding connections, providing 400 volts at 50 Hz across three phases with a power factor of 0.8. It supports a standby rating of 33 kVA at 27°C and a continuous rating of 30 kVA at 40°C, achieving 87.9% efficiency at full load, along with 1% voltage tolerance, class H insulation, and IP23 protection.
Fuel Consumption and Tank Configurations
This diesel-powered generator uses 5.27 liters per hour at 75% PRP and 7.00 liters at 100% PRP, with a specific consumption of 214.5 g/kWh at 75% PRP. Fuel tank options range from an 80-liter internal plastic tank offering 15.18 hours autonomy at 75% PRP, to metal tanks from 65 liters (internal, 12.33 hours) up to 500 liters (sub-base mounted, 94.88 hours), with larger tanks adding extra dimensions and weight such as up to 323 mm length, 354 mm height, and 216 kg for open versions.
Electrical Setup and Protection
Operating on a 12-volt battery and electric start system, the generator delivers 400/230 volts at 50 Hz over three phases with a power factor of 0.8. It handles a maximum current of 48 amps and nominal of 43 amps, safeguarded by a 50-amp circuit breaker, and meets standards including ISO 8528-5:2013 G2 class load acceptance, plus EC directives for safety, compatibility, voltage limits, noise, and emissions where applicable.
Control Panel Choices
Available panels include the manual remote start (MRS) with automatic mains failure, three-phase measurements, protections, running hours display, and logging for 50 events. The automatic control panel (ACP) provides auto mains failure functionality, full monitoring, and optional remote or I/O modules. The modular parallel panel (MPP) supports up to 32 units in parallel with mains or multi-gen applications, event logging, and communication options, all powered through circuit breakers or terminal bus bars, plus extras like external terminal boards or differential protection.
Enclosure Variants and Handling
Configurations include open, canopy, and extra silent canopy models, with the open version at 1875 mm long, 1000 mm wide, 1186 mm high, and 746 kg, featuring a welded steel baseframe, anti-vibration mounts, and crane handling hole. The standard canopy measures 2200x1020x1292 mm at 959 kg with galvanized weatherproofing and lockable doors.
