1 / 13 page  102045_01_en 1 ASI QUINT 100-240/2.4 EFD 01/2005 Data Sheet Short Description One Cable – Two Functions AS-Interface (AS-i) enables maximum control potential with its simplified installation technique. Information and power supply are transmitted at the same time via a two-wire cable to minimize connection points. AS-i power supply units use an integrated filter to ensure that the modulated data flow is not affected. In addition to this, the short-circuit and idling-proof voltage output provides a current reserve of approximately 60%. This means that even loads with high inrush currents can be started safely. Safety Through Automatic Ground Fault Detection If two ground faults occur in an AS-i system, this can cause an unauthorized machine startup or mean that the machine can no longer be stopped. To prevent this from happening, AS-i power supply units from Phoenix Contact indicate the first ground fault as it occurs. The message is indicated by the LEDs on the device and reported via an output. In the default configuration, the signal of the message output can be used to stop the system via the control program or the PLC. There is also the option of configuring the AS-i power supply unit so that the AS-i power is switched off automatically when a ground fault is detected. This prevents potential danger to operating personnel and machines/systems before it happens. Global Use The wide range input, which can be used to operate the AS-i power supply units from Phoenix Contact with all popular single-phase AC and DC networks, provides the starting point for global use. Integrated Harmonic Filter EN 61000-3-2 came into force on January 1, 2001. As from this date, all primary-switched power supplies that are directly connected to the public low-voltage network must be equipped with a harmonic filter to suppress the supply of high-frequency reverse currents in the power supply company network. All AS-i power supply units from Phoenix Contact are equipped with an active PFC filter (Power Factor Correction). In addition to the filter function, this feature provides mains buffering of more than 20 ms over the entire input voltage range. Wide Range of Applications The ASI QUINT 100-240/2.4 EFD power supply unit meets the noise immunity and noise emission requirements of EN 55022 Class B. The device can therefore be used universally in harsh industrial environments as well as in commercial and domestic environments, which are susceptible to interference.
