Review of SX460 Stamford Automatic Voltage Regulator

The Stamford SX460 voltage regulator can be regarded as a key component within your diesel generator. It is responsible for both the quality and the reliability of the power that your diesel generator produces. While it is a small, economical and critical component, it is the brain behind the automatic regulation of the voltage produced by your generator.  The Automatic Voltage Regulator is responsible for ensuring the necessary flexibility and responsiveness that your Stamford alternator needs, as it allows it to quickly respond and adapt to the load impacts at all stages of its operation. This is because, in most applications, the loads are both constantly fluctuating and unpredictable.

Irregular, unstable or unreliable voltage outputs from your generator could result in downtime, loss of productivity, loss of convenience, safety hazards and equipment damage. Using a Stamford SX460 AVR will deliver dependable protection to your personnel and your electronic sensitive equipment.

How does it work?

  • Inside the alternator is a small magnetic field. When the engine drives the generator into motion, this field induces a small voltage, called residual voltage on the windings of your generator.
  • The AVR then receives excitation from the residual voltage and starts producing more voltage onto the generator’s exciter until the necessary voltage are reached.
  • Output voltage is monitored by the AVR, while controlling input voltage for the generator’s exciter, through decreasing or increasing generator control voltage.
  • The AVR does calculations of how much voltage needs to be sent to the exciter several times per second. This creates a stable output voltage at the predetermined set point while compensating for load, engine speed, and temperature and generator power factor.

Benefits of SX 460 Stamford Automatic Voltage Regulator

It compensates for load, speed, temperature and power factor. As it has a closed loop control, this provides a load regulation of +/- 1.0%. It includes an adjustable damping or stability circuit, as well as an under-speed protection circuit. An LED indicates when the Under Frequency Roll-Off (UFRO) circuit is working. It is a non-condensing unit. As with all automatic voltage regulators, it is designed to protect equipment by monitoring and adjusting the output voltage of a generator. This product also has many capabilities such as surge suppression, short circuit protection and line noise reduction. They also balance phase-to-phase voltage and ensure the stability of the generator. As well as regulating the generator voltage, its circuitry includes under speed and sensing loss protection features.
