Multiquip 0601820671 Automatic Voltage Regulator NTA-5A-2DB - OEM Replacement Part

This automatic voltage regulator maintains stable output voltage across varying loads in Multiquip industrial generator sets. The NTA-5A-2DB regulator continuously monitors and adjusts excitation to the revolving field synchronous generator, ensuring consistent power delivery across three-phase (208-480V) and single-phase (240/120V) configurations. In generators equipped with this AVR, the excitation system responds dynamically to load demands without a fixed ceiling limitation, protecting sensitive equipment from voltage fluctuations.

Designed for generators producing 20-25 kVA prime output at 1,800 RPM and 60 Hz frequency, this regulator works in conjunction with the star-neutral zigzag armature connection. It manages voltage stability for both main power outputs and auxiliary 120V circuits rated at 4.8 kW. The unit integrates with the generator control panel's voltage adjustment system and overload protection circuitry including OCR and main circuit breakers.

Compatible with the following Multiquip generator models:

• DCA25SSIU
• DCA45SSIU3
• DCA45USI
• DCA70USI
