SX460GP Automatic Voltage Regulator

If the voltage from your generator is hunting, too high or collapsing, the AVR is the first part to check. SX460GP is a replacement regulator for Stamford alternators.

About this part

Sensitive loads such as computers, inverters and motor drives depend on a steady voltage. The regulator is a small, inexpensive board that protects everything downstream of the generator.

Features

Input voltage is between 95 and 135 Volts ac or 190 to 264 Volts ac
Frequency is 50 or 60 Hertz nominal
Single phase
Output voltage is a maximum of 90 Volts dc at 207 Volt ac input
Resistance is 15 Ohms minimum
Unit power dissipation is 10 Watts minimum

When to replace it

Output voltage that is too high, too low or unstable
No output voltage although the engine runs normally
Lights flickering or voltage dipping as loads switch on
A burnt or damaged board after a lightning strike or short

Before you order

Match the AVR to the alternator: sensing (single or three phase), excitation type (brushless or brush type), supply voltage and the physical mounting all have to suit. Note the wiring before disconnecting the old regulator.

Match the number stamped on the part you are removing, or the number in your engine or alternator manual, before ordering. Part numbers are shown for reference so the right replacement can be identified.

Questions

Will a universal AVR work on my alternator?

Often, if the sensing, excitation current and supply voltage suit. Send us the alternator make and model and the old AVR number and we will confirm.

What is an "alternative" AVR?

A regulator made to replace the original part on a specific alternator brand, at a lower cost than the brand part.
