Product Overview
The AKSA APD1250C is a heavy-duty diesel generating set built for dependable high-capacity standby power use across commercial, industrial, infrastructure, construction, data centre, agricultural, and critical backup power applications. It delivers 1250 kVA / 1000 kW standby power, making it suitable for sites that require large-scale 50Hz, 3-phase electrical supply.
Powered by a Cummins KTA38G9 diesel engine, the APD1250C uses a 12-cylinder, 37.8-litre, V-type diesel engine running at 1500rpm. The engine is turbocharged and aftercooled, with direct fuel injection, electronic governor control, replaceable fuel, oil and dry element air filters, water cooling, radiator and fan assembly, and 12/24V DC starter and charge alternator system.
The generator is supplied with an HCI634K alternator, offering brushless single-bearing operation, 4-pole construction, Class H insulation, self-excitation, self-regulation, solid-state automatic voltage regulation, and 2/3 pitch stator winding for improved harmonics. This helps provide stable output for high-capacity standby loads.
The APD1250C is available in open or enclosed canopy configuration. The generator set includes a heavy-duty base frame, anti-vibration mounting, fuel tank options, flexible fuel connection hoses, manual oil sump drain valve, industrial exhaust silencer, steel bellows, starter battery with rack and cables, and service-friendly access for routine maintenance.
