Power supply PS3-100/iNELS

• PS3-100/iNELS is a stabilized switching power supply, with the total
power of 100 W.
• Used to supply central units and external master within intelligent
electro-installation iNELS.
• Through BUS separators from the supply voltage BPS3-01M and BPS3-
02M, it supplies supplies BUS lines from which iNELS peripheral units
are also powered.
• Used in the instrumentation fi eld.
• Fixed output voltage DC 27.6 V and DC 12.2 V, galvanically isolated
from the mains.
• Power source of 27 V and 12 V have a common ground terminal GND.
• Electronic short circuit protection, high-capacity and thermal overload, over voltage.
• UPS functions – backup of output 24V and 12V on connected batteries.
• Recharging the batteries from 27 V source.
• Protection battery backup fuse – protection against short circuit and
reverse polarity battery.
• Continuously adjustable maximum battery charging current.
• Indication of operating and fault conditions 6 LED diodes on the front
panel of the power supply.
• 2 STATUS outputs with open collector for reporting operational status
of the source.
• Source supplies power to the priority system iNELS, the remaining
power is used for rechargeable batteries.
• When the battery is fully discharged, the battery is automatically disconnected from the load.
• PS3-100/iNELS in 6-MODULE version is designed for mounting into
a switchboard, on DIN rail EN60715
