Characteristics
• PS3-30/DALI provides 30 W total power for both iNELS bus (27 V DC) and DALI
devices (16 V DC), ensuring effi cient power distribution for central units, external
masters, and peripheral devices including DALI BUS.
• PS3-30/DALI includes an internally integrated bus isolator to power one branch
of the iNELS BUS, maintaining reliable and isolated power supply for connected
peripheral units.
• Equipped with electronic protection against short circuits, overvoltage, power
overload, and temperature overload, ensuring safe and stable operation.
• Off ers over 85% effi ciency, optimizing energy consumption and reducing heat
generation.
• Compact Design: 3-module unit designed for easy mounting on DIN rail EN60715,
allowing for streamlined installation in switchboards and control panels.
• Supports a wide input voltage range of 100-240 V AC and operates in temperatu-
res from -20°C to +55°C, suitable for various environmental conditions.
• Meets safety standards EN 60950-1 and EN 62368-1, EMC standards EN 55032 and
EN 55024, and is RoHS compliant, ensuring adherence to international safety and
environmental regulations.
General instrucions
CONNECTION TO THE SYSTEM, INSTALLATION BUS
iNELS3 peripheral units are connected to the system through the BUS installation. Installa-
tion BUS conductors are connected to the terminal units to BUS+ and BUS- terminals, wires
cannot be interchanged. For installation of BUS it is necessary to use a cable with a twisted
pair of wires with a diameter of at least 0.8 mm, the recommended cable is iNELS BUS Cable,
whose features best meet the requirements of the BUS installation. Bearing in mind that in
terms of all the properties is it is possible in most cases also use the cable JYSTY 1x2x0.8 or
JYSTY 2x2x0.8, however it is not recommended as the best option. In the case of a cable with
two pairs of twisted wires it is not possible to use the second pair of the other for modulated
signal due to the speed of communications; it is not possible within one cable to use one pair
for one segment BUS and the second pair for the second segment BUS. For installation of BUS
it is vital to ensure that it is kept at a distance from the power lines of at least 30 cm and must
be installed in accordance with its mechanical properties. To increase mechanical resistance
of cables we recommend installation into a conduit of suitable diameter. BUS topology instal-
lation is free except for the ring, wherein each end of the bus must terminate at the terminals
BUS + and BUS- peripheral unit. While maintaining all the above requirements, the maximum
length of one segment of the installation BUS can reach up to 300 m. Due to the data commu-
nication and supply of units in one pair of wires, it is necessary to keep in mind the diameter of
wires with regards to voltage loss on the lead and the maximum current drawn. The maximum
length of the BUS applies provided that they comply with the tolerance of the supply voltage.
CAPACITY AND CENTRAL UNIT
You can connect the power supply PS3-30/Dali to the central unit CU3-08/09/10M on a single
BUS using BUS1+ and BUS1- terminals, and to the Dali bus via DA+ and DA- terminals. The BUS
can support up to 32 units depending on the power requirements of the devices, and the Dali
BUS can handle up to 64 devices. Ensure that the total current on any BUS line does not exceed
1000 mA. If connecting units that require more than 1A, an additional power supply may be
necessary.
GENERAL INFORMATION
To operate the unit, it is necessary that the unit is connected to a central unit CU3 series, con-
nected to the central unit of the system CU3, or to a system that already contains this unit as its
expansion to include further system.
