Electric Power Generation

3512A (50 Hz)

Producing reliable power from 1000 kVA to 1400 kVA ekW at 50 Hz, our 3512 diesel generator sets are engineered for your mission critical, continuous, standby and prime applications. Each meet ISO 8528-5 transient response requirements and accept 100 percent rated load in one. 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. Our EMCP4 control panel provides a flexible control platform, with an easy-to-use display — it’s your single source for management and diagnostics tools. We know it’s not just quality that matters but customization. Choose from a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging options to work with your spatial restrictions and environment conditions.
