It features Surface Mounting Technology (SMT) construction, parallel operation capability, and under-frequency roll-off protection with LED indication. The unit weighs 300g, measures 14.6cm x 11.6cm x 4.7cm, and is housed in a black enclosure.
This AVR model supports a build-up voltage of 4V AC at its terminals and accepts a power input voltage range of 100-264V AC. The sensing input voltage is jumper-selectable between 100-130V or 170-264V, with frequency selection for 50Hz or 60Hz. It delivers a maximum output voltage of 82V DC at 200V AC input, with a continuous current output of 4A and transient capability of 7.5A for 10 seconds. Over-excitation protection is set at a typical 65V DC default value.
The AS440 is commonly used in industrial generators, telecom backup systems, and marine applications where stable voltage regulation is critical. Buyers typically source this for its compatibility with Stamford alternators and its ISO 9001 certified manufacturing. It is available in individual packaging, with outer cartons holding 40 units, and ships from Shanghai port. Minimum order quantities are negotiable, with trial orders accepted for 1 piece.

Before ordering the AS440 AVR, verify its compatibility with your specific Stamford alternator model and confirm whether the sensing input voltage range matches your system’s requirements. Check the supplier’s current ISO 9001 certification status and request test reports for the unit’s performance under load conditions.
Confirm logistics details such as lead time, shipping port (Shanghai), and Incoterms (e.g., FOB) with Wuxi Kerui Electric Co., Ltd. The packaging is standard export cartons with 40 units per box, but buyers should clarify handling and shipping costs for their order size. Payment terms should also be negotiated directly with the supplier.
For quality assurance, inspect the AVR’s build-up voltage, output stability, and protection features upon receipt. Request documentation such as the ISO 9001 certificate, test reports for over-excitation and under-frequency protection, and a conformity declaration. Conduct functional tests in a controlled environment before deployment in critical applications.
