Hahn & Sohn HDE313RSP3-3 diesel generator
The diesel generator Hahn & Sohn HDE313RSP3-3 represents a reliable source of electrical energy for demanding applications. The unit is designed in accordance with the ISO 8528 standard and complies with the EU Stage 3A emission standard.
- The heart of the machine is a six-cylinder in-line engine PEZAL PD6128ZICRA2 with a displacement of 11.8 l, featuring electronic speed control and Common Rail fuel injection, delivering up to 307 kW (PRP according to ISO 3046). The engine operates at 1500 rpm and is liquid-cooled.
- The alternator section consists of a synchronous brushless unit PEZAL PPA313-250V with PMG excitation, insulation class H, protection rating IP23, and electronic voltage regulation AVR (±1 %). Low harmonic distortion (THD < 2.5 %) ensures safe power supply for sensitive equipment.
- The unit is housed in a robust, soundproofed steel enclosure with powder coating and equipped with a microprocessor control panel ComAp InteliLite IL4 AMF25 with a graphic display and Czech language menu.
- Thanks to the integrated fuel tank with a capacity of 750 liters, it allows approximately 11 hours of operation at 100% load.
