Overview

Producing reliable power from 1320 kVA to 1750 kVA at 50 Hz, our 3512B diesel generator sets are made to meet your mission critical, continuous, standby and prime applications — an d match your power standards. Each meet ISO 8528-5 transient response requirements and accept 100 percent rated load in one step. Our 3512B generator sets are designed for either low fuel consumption or low emissions. Our integrated control system, including ATS and switchgear keeps power supply consistent and keeps you connected to your fleet with on-site and remote monitoring options. Get management and diagnostics tools in one, with our EMCP 4 control panel options, all designed with a user-friendly interface. You have specific power needs and we have a broad range of accessories and bolt-on system expansion attachments to select from. Flexible packaging options work with your spatial restrictions and climate.
