Power units

The power units transfer current from a source, such as a supply network, to a device, such as a computer. In this time, they convert the characteristics of the voltage and current. Their main role is to ensure uninterrupted supply, reducing the losses of production and distribution

       

       

Description:
The power units transfer current from a source, such as a supply network, to a device, such as a computer. In this time, they convert the characteristics of the voltage and current. Their main role is to ensure uninterrupted supply, reducing the losses of production and distribution.

The main features of a power supply are:

  •     High efficiency
  •     The wide input voltage
  •     The low sizes and weights
  •     The small index of generated perturbations
  •     Appropriate protective elements: against overcurrent, short circuit, overvoltage
  •     Galvanic separation of input and output

Specifications:

  •     Different powers: from 15W to 400W
  •     With one or multiple exits
  •     With simple or sealed enclosures and with integrated fans, for forced exterior cooling
  •     Different voltages: 5V, 7,5V, 12V, 13,5V, 15V, 24V, 27V and 48VDC
  •     Protected against overload, overheating and short circuit
  •     Works at temperatures between -10°C and +60°C and a relative humidity of 20-90% RH
  •     Adjustable output voltage in the range of -5/+10% of rated voltage
  •     Efficiency: 70-94%
  •     ECO mode operation for energy saving
  •     Plugs programmable for power management
  •     Emergency stop function (EPO)

Applications:

  •     In most of the applications in automation, engineeringetc
  •     In most of the industries

Strengths:

  •     Low weight and small volume at high power
  •     Increased efficiency
  •     Small capacity of the filtering capacitors for high frequencies
  •     No perceptible disturbance at hearing
  •     Resistance to disturbances in the network and short power failures
  •     Short-circuit protection integrated in the circuit's source
