PS3-100/iNELS is a switched stabilized power supply with a total output of 100 W.
It is used to power central units and external masters within the iNELS bus wiring.
Through the bus separators from the supply voltage BPS3-01M and BPS3-02M, it supplies power to the bus branches of the BUS, from which the iNELS peripheral units are further powered
PS3-100/iNELS is also used in the field of MaR (measurement and regulation).
The PS3-100/iNELS power supply has two fixed output voltage levels of 27.6 V DC and 12.2 V DC. These output voltages are galvanically separated from the AC network.
Voltage sources 27 V DC and 12 V DC have a common terminal GND.
PS3-100/iNELS is equipped with electronic protection against short circuit, over- five, power and temperature overload.
UPS Function- Backing up outputs with backup batteries.
After connecting the AC supply voltage, the backup batteries are recharged from a 27.6 V DC source.
The power supply supplies power primarily to the iNELS system and the remaining power is used to recharge the backup batteries.
When the backup batteries are complelely discharged, the battery is automatically removed from the load.
Infinitely adjustable maximum charging current of backup batteries.
Backup batteries are secured by a fusible fuse to protect against short circuits or reverse polarity of the batteries.
Signalling of operating and fault conditions by means of 6 LEDs located on the front panel of the power supply.
2 STATUS outputs with open collector for reporting operating power supply systems.
PS3-100/iNELS in 6-MODULE version is designed for mounting on a DIN rail EN60715.
