Origin: France

Brand: Leroy Somer, Caterpillar

Model: EM15

The Leroy Somer EM15 AVR Voltage Regulator Excitation Module is a power electronics component designed to provide excitation current to the generator that is controlled by the Integrated Voltage Regulator (IVR) feature in the EMCP 4 controls.

FEATURES of Caterpillar Leroy Somer EM15 AVR:

• Over-excitation protection – limit can be adjusted via a potentiometer (IEXC.)

• Green status LED indicating unit is powered on

• Red status LED indicating excitation current limiting When used with EMCP 4.3/4.4 and IVR-compatible

EMCP 4.1/4.2 controllers, the Integrated Voltage Regulator system o rs:

• Automatic Voltage Regulation (AVR)

• Programmable stability settings

• Soft start control with an adjustable time setting in

AVR control mode

• Dual Slope Under Frequency (Volts / Hz) regulation

• Three-phase or single-phase generator voltage (RMS) sensing/regulation in AVR mode EMCP 4.3/4.4 and IVR-compatible EMCP 4.2 controllers also offer:

• Power Factor Regulation (PF)

• Generator paralleling with reactive droop compensation

• Line drop compensation
