Power Supplies
IE340 switches can be powered with the IE048-480 power supply from
Allied Telesis. They can also be powered with power supplies from third-
party manufacturers that meet the requirements in Table 9 on page 51 and
“Power Specifications” on page 130. They should also support the
environment of the location site.
Use a UL-listed DC power supply with 48VDC/10A output. It should
be suitable for the operating altitude and maximum ambient
temperature of the physical location of the switch. Refer to the
installation instructions from the manufacturer for installation and
safety guidelines.
IE048-480 Power
Supply
The IE048-480 power supply endures harsh environments such as those
found in industrial applications. Here are main features:
480W output power
Wide input voltage range: 85 ~ 264Vac
Wide operating temperature range: -25 ~ 70°C
Electromagnetic immunity (EMI) suitable for industrial applications
High efficiency: 94% @230Vac
150% peak current capability
Active PFC: PF type. 0.93 @230Vac
Protection circuits: peak-current, over-current, over-voltage, over-
temperature
Remote ON/OFF
Output power confirmation relay (DC_OK)
DIN rail mount
The IE048-480 power supply and other non-compliant UL/EN/IEC
61010-1 and 61010-2-201 power supplies must be installed in fire
protection enclosures when installed on walls of combustible
material (e.g., wood). Additionally, the floor area directly below the
power supplies should be non-combustible (e.g., metal or concrete)
and free of combustible material (e.g., paper, plastic, or wood).
