POWER SUPPLIES

In many applications, the voltage from the grid is too high or has to be converted to DC voltage or to a different AC waveform. It is therefore transformed by modern power electronics. A transducer measures the output current to ensure stable power supply.

Power supply is critical for the effective function of applications such as cell phones base stations or hospitals security systems who must always remain operational. In case of failure (short circuit, unexpected connection to earth, etc.) or fault in the grid interrupting the power, batteries or Uninterruptible Power Supplies (UPS) temporarily provide emergency power. Transducers are used to control the charge and discharge of these batteries as well as the switch to the batteries and UPS.

Typical applications for Power Supplies

• UPS: Uninterruptible Power Supplies
• SMPS: Switched Mode Power Supplies
• Telecom power supplies
• Airport lighting power supplies
• Lighting power controller
• Battery chargers
