GENERAL CHARACTERISTICS
The isolation transformers used in this catalog are designed and implemented with the following characteristics:

  • Double insulation or reinforced insulation between the primary winding el’avvolgimento secondary;
  • Compliance with the surface distances in air and through the insulation to withstand high voltage applied to the test;
  • Design and use of materials and thermal insulation of high class to ensure both high performance at nominal load is a resistance to prolonged overload;
  • Accurate implementation of all output (hollow interior, external sockets, terminals, etc.). To ensure, in any case the fundamental requirement of isolation.
  • Impregnation complete cycle with vacuum-pressure processors with consequent improvement of the
  • technical features and power.
  • UL/CSA File E 309790.


ELECTRICAL CHARACTERISTIC

 

  • Frequency-Rated
    The processors are designed for the frequency of 50Hz, but can also function properly at 60Hz.
  • Tensions
    Tensions of entry are admitted voltage indicated by plate affixed to the product.

Output voltage: refer to the primary voltage rating, with nominal load and power factor of 1.
The voltage drops vacuum are particularly dependent on output. In the product details listed in the catalog shows the data referred to:

  • Short-circuit voltage expressed as a percentage of nominal voltage primary;
  • Voltage drop vacuum charged as a percentage of secondary voltage;
  • Maximum power apparent rush to download secondary function of power factor of load.

The isolation transformers built to be installed in premises used for medical purposes must be equipped electrostatic screen as specified by the standard EN 61558 “General requirements for safety of electrical appliances.” The screen electrostatic between primary and secondary education that avoids the eddy current on the electricity grid are found sull’avvolgimento secondary and endangering the patient.
The screen on all processors of any power is connected to the terminal, is edited the user to connect the screen with the planting of land.
According to the standard currently in force for central secondary status control insulation is absolutely necessary, because the insulation to
ground an electrical system can be verified from anywhere in the system and the earth.


WARNINGS FOR WIRING
Verify that the processors into the temperatures do not exceed the limits prescribed by the rules. Use the appropriate cables according to the current game and the capacity of the terminals. In addition to special care not to tighten the insulating sheaths under the terminal
screws. In fact, a bad contact can lead to localized heating that can lead to damage to components. The installation and replacement of transformers is to be performed by qualified persons.
