The E000-23408/1P is a Genuine OEM MX341 UL AVR for STAMFORD generators. UL-certified automatic voltage regulator for Cummins Generator Technologies, meeting North American standards. The MX341 is an analogue, 2-phase sensing Automatic Voltage Regulator (AVR) powered by a permanent magnet generator (PMG), forming part of the excitation system for brushless generators. The PMG-powered design isolates the AVR control circuits from the effects of non-linear loads and reduces radio frequency interference at the generator terminals, while also providing sustained generator short circuit current.

Key features

• 2-phase voltage sensing with PMG excitation power
• Soft-start circuit for smooth, controlled output voltage build-up
• Under-frequency roll-off (UFRO) protection of the excitation system
• Improved motor starting performance and short circuit current support
• Adjustable stability, droop, and volts/Hz slope for varied applications
• Operating temperature range: -40 °C to +70 °C

Compatible STAMFORD alternators

Supplied as standard on P7 and S7 alternators. Also available for UC22, UC27, HC4, S4, HC5, S5, HC6, and S6 alternator frames equipped with a PMG.
