Powered by an AKSA A4CRX47 diesel engine, this 400/230V, 50Hz, 3-phase generator is designed for reliable standby and prime power applications, with DSE6120 control, brushless alternator, integrated fuel tank, easy maintenance access, and optional sound-attenuated canopy configuration.
Brand: AKSA
Product Overview
The AKSA APD55A is a diesel generating set designed for dependable standby and prime power use across small commercial premises, farms, workshops, site cabins, light industrial units, construction sites, and general backup power applications. It delivers 55 kVA / 44 kW standby power and 50 kVA / 40 kW prime power, making it suitable for installations requiring stable 400/230V, 50Hz, 3-phase electrical supply.
Powered by an AKSA A4CRX47 diesel engine, the APD55A uses a 4-cylinder, 4.95-litre, in-line diesel engine running at 1500rpm. The engine is naturally aspirated and water cooled, with direct injection fuel system, mechanical governor control, replaceable fuel, oil and dry element air filters, cooling radiator and fan, starter battery system, flexible fuel connection hoses, industrial exhaust silencer, steel bellows, and a 12/24V DC starter and charge alternator system.
The generator is supplied with a brushless single-bearing alternator with revolving field design, 2/3 pitch stator, flexible disc rotor, Class H insulation, self-excitation, self-regulation, solid-state automatic voltage regulation, and direct-drive centrifugal blower cooling. This supports stable electrical output for standby and prime power loads.
Control and protection are handled by the DSE6120 control panel. The controller monitors mains supply, generator voltage, current, frequency, engine oil pressure, coolant temperature, battery voltage, running hours, alarms, and shutdown conditions. The APD55A is available in open or sound-attenuated canopy configuration depending on installation requirements.
