Item Specications
Power input ● Supports one AC input or two AC inputs
● Rated voltage: 200–240 V AC
● Rated frequency: 50/60 Hz
Maximum
power
consumption
of the main
control
module
70W
Power output ● Output voltage: 42–58 V DC (rated voltage: 53.5 V DC)
● Output power of two power module supplies: 2000 W (200–
240 V AC); 940 W (linear derating at 85–175 V AC)
● Output power of a single power module supply: 1000 W
(200–240 V AC); 470 W (linear derating at 85–175 V AC)
WAN port ● Supports two WAN ports. WAN1 is used to connect to the
management system, and WAN2 is used for maintenance.
The ports support autonegotiation of 10/100/1000 Mbit/s
communication rates.
● Connect shielded network cables to the WAN ports.
LAN port ● Supports two LAN ports, which can be connected to the
LAN. The ports support autonegotiation of 10/100/1000
Mbit/s communication rates.
● Connect shielded network cables to the LAN ports.
RS485 serial
port
expansion
● Output voltage: 13–15 V DC (rated voltage: 14.5 V DC)
● Four RS485 ports with the default communications rate of
9600 bit/s
● COM1–COM3 ports provide 12 V DC power.
● The power supply can be switched on or o and is on by
default.
PoE expansion Supports two PoE (GE) ports for expansion of the PoE bus, and
supports network isolation and ring network.
AIDI
expansion
(RJ45)
● Output voltage: 13–15 V DC (rated voltage: 14.5 V DC)
● Provides ve universal AIDI ports for connecting to sensors
such as smoke sensors, water sensors, and NTC sensors.
AIDI_1 to AIDI_3 are full-function AIDI ports, and AIDI_4 to
AIDI_5 are simplied AIDI ports without type identication.
● The power supply can be switched on or o and is on by
default.
