AS440 New - Factory Sealed Voltage Regulators AVR

Product Overview

The AS440 is a high-performance, half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR), specifically designed for brushless generators. This sophisticated component is part of the excitation system for a wide range of industrial and marine alternators, ensuring stable output voltage regardless of load variations. Being New - Factory Sealed, this unit guarantees maximum reliability, factory-fresh circuitry, and a full service life, making it the ideal choice for critical power applications and generator maintenance.

Key Features

• Precise Voltage Regulation: Maintains generator output voltage within a tight $\pm1.0%$ range, protecting sensitive electronic equipment.
• Under-Frequency Roll-Off (UFRO): Built-in protection circuit that reduces the output voltage if the engine speed drops, preventing damage to the generator.
• Surface Mount Technology: Utilizes advanced SMT for a compact footprint and high resistance to vibration and environmental stress.
• Parallel Operation Support: Features a "droop" input for easy integration into parallel running systems with other generators.

Item Condition (New - Factory Sealed)

• Functional Status: Brand new, never used, and in original factory condition with internal components perfectly preserved.
• Physical State: Pristine condition; the unit remains in its original static-shielding or factory-sealed packaging to ensure zero environmental exposure.
• Visual Reference: Please refer to the product images to verify the specific manufacturer branding and serial number details; the item pictured is the actual factory-sealed unit you will receive.
• Note: Installation should be performed by a qualified generator technician; ensure all jumpers are set correctly for your specific alternator's frequency (50/60Hz).
