Transformers with motor-driven tap changers can be controlled with automatic voltage regulators.
Actuation of the motor drive leads to a voltage change by one tap. If the difference between actual voltage and set-point exceeds a certain limit, a regulation comand ("up", "down") is initiated.
SPRECON-E-C-AVR can be adapted to customer-specific requirements to the greatest possible extent. Moreover, several units can be operated in parallel mode, which is based on the master/follower principle. Thereby, the circulating reactive current is monitored.

The new automatic voltage regulator model S125 has been designed to perform its duty even in the most difficult work condition, on new or old-fashion brushless excitation units equipped with a dinamo. This device belongs to the smallest AVR family available on the market, but it is the most powerful since it supplies 5 A current.

AIC1531 is a dual input regulator with VAUX
switch capable of delivering 3.3V/500mA
continuously. The output power is provided from
three independent input voltage sources on a
prioritized basis. Power is always taken in priority
using the following order VCC, VSBY, and VAUX.
The AIC1531 meets Intel’s “ Instantly Available ”
power requirements, which follows the
“Advanced Configuration and Power
Interface“ (ACPI) standards. When either VCC or
VSBY is present, the device automatically enables
the regulator and produces a stable 3.3V output
VOUT. When only VAUX (3.3V) is present, the
device provides a low impedance direct
connection (120mW typ.) from VAUX to VOUT.
The AIC1531 also prevents excessive current
from flowing VOUT to either input voltage or
ground when the output voltage is higher than
the input voltage.
All the necessary control circuitry needed to
provide a smooth and automatic transition
between all the three supplies has been
incorporated. This allows both VCC and VSBY to
be dynamically switched without loss of output
voltage.

Microprocessor Voltage Regulators (1 Phase)
AC/DC Micro Processing Control Voltage Regulator ; are RISC Microprocessing semi conductor type smart instruments. That's why they can be used with 100% safety in sensible electronical apparels. AC/DC Microprocessing controlling Voltage Regulators are functionning based on true RMS Effective measurement value. Thus the network input voltage is not affected by sudden changes in network voltage or wave shape failure hence they might work easily with output voltage fast correction ( 220 VAC , ± 1 ).

3-Terminal Fixed Positive Voltage Regulator
General Description
These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. With adequate heatsink they can deliver output currents up to 1 ampere. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
Features
- Output Voltage Range 5 to 24V
- Output current up to 1A
- No external components required
- Internal thermal overload protection
- Internal short-circuit current limiting
- Output transistor safe-area compensation
- Output voltage offered in 4% tolerance
