Description

three phase frequency converters 50/60Hz 3:470V output adjustable voltage

PRODUCT DESCRIPTION:
An extremely compact device with a high performance.
Designed using the latest technologies, it’s a very reliable and flexible equipment for the use as:
– Frequency converter
– Electronic voltage stabiliser
– Electronic voltage regulator

ELECTRONIC VOLTAGE REGULATOR
Comparable to a traditional motorized voltage regulator, with an electronic control circuit, but fully static and absolutely fast (reaction time is less than 1mS).
The set voltage is maintained even if the load or the input voltage suddenly change. Through a 0-10V signal connected to the remote terminals or through the front panel bottons it is possible to change the output voltage from 0 to 270V. Dynamic response to the set voltage is 40µS.

ELECTRONIC STABILIZER
An output autotransformer guarantees the set voltage even to 270V in presence of a lower input voltage.

FREQUENCY CONVERTER
With any input frequency, the device supplies a 50Hz or a 60Hz output using the front selector or the remot control.
(Different frequencies are available on request.)

APPLICATIONS
This equipment may be used in many applications such as tast banks of electric and electronic equipments (motors, resistors, etc.) or at the end of production lines to regulate/stabilize voltage and frequency for routing tests, to avoid continuous voltage variations or spikes which can determine the fail of the test or, worst, the damage of a product during the test. If equipe with an isolation transformer it can guarantee the total immunity of the load from noise or disturbances from the network

SYSTEM ADVANTAGES 
Why a static voltage stabilizer?
As for the electromechanical voltage stabilizers and the uninterruptible power supplies this equipment protects the load rom the network, but with the following advantages:
– Strongly reduced size and weight
– Total absence of moving parts, no need of maintenance, no periodic costs.
– Improved efficiency, therefore less Energy consumption with the same load level.
– Dynamic response speed (< 1 mS), better performance and extremely higher protection of the load
– Improved output voltage accuracy, better than 1%
– Total elimination of network inpurities (output voltage is generated starting from a DC voltage)
– Absolute output frequency stability (001%).

Against a UPS

  • Saving in costs a sit does not include batteries which are not necessary for the purpose of this equipment
  • No maintenance cost due to battery replacements .
  • Care of environment as batteries are harmful for the environment
  • Total elimination of network inpurities (output voltage is generated starting from a DC voltage)
