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
