Select Units

Overview

The 3512 diesel generator sets have been developed to meet your mission critical, continuous, standby and prime applications. Producing reliable power from 1000 to 1400 kVA at 50 Hz, each generator set is designed to meet ISO 8528-5 transient response requirements and accept 100 percent rated load in one step. And each is designed for low fuel consumption reducing operating costs. Our integrated control system, including Cat® UPS, ATS and switchgear, secure your power supply and keep you connected to your fleet through on-site and remote monitoring options. The EMCP4 control panel provides a flexible control platform, with an easy-to-use display — it's your single source for management and diagnostics tools. The EMCP 4.4 controller provides multi-generator set paralleling capability, giving you the ability to add generator sets to match your growing power requirements. It's not just quality that matters but customization, choose from a broad range of accessories and bolt-on system expansion attachments. Discover our flexible packaging options to work with your spatial restrictions and environmental conditions. Our 3512 generator sets are developed for such prerequisites, so that you can meet your specific power needs.
