Power Supply Specifications
Rack Mount Models (except Electric Utility models)
DC Power Requirements
The IOLAN DC is supplied with an integral Terminal Connections block to facilitate connection to a
DC source(s). The DC supply(s) should have adequate over-current protection within the closed rack
system and comply with local or national standards applicable to the installation territory. You need
wire gauge 20 to 22 AWG to connect the IOLAN rack mount unit to the power source.
Note:
The equipment must be grounded for safety and to ensure ESD protection for correct
operation and protection of the internal circuitry.
AC Power Requirements
AC power rack mount units come with standard power cords, specific to your country, that should be
used to power the IOLAN unit.
Medical Unit Models
The MDC model comes with standard power cords, specific to your country, that should be used to
power the IOLAN unit.
Electric Utility models
Power Options
The Electrical Utility series of IOLAN units can be purchased with two different power source
options;
HV - Single High Voltage power input with nominal AC range of 100V-240V (50-60Hz) or
nominal DC range of 125V-250V.
DHV - Dual Redundant High Voltage power inputs with nominal AC range of 100V-240V (50-
60Hz) or nominal DC range of 125V-250V. Either power source can be used to supply
power to the unit. When both power inputs are live, the unit operates in a load sharing
fashion. Note that the power input pairs are electrically isolated from each other. This means
that when using both power inputs either input can be in either the AC or DC range.
DC Power Requirements
The IOLAN can be powered via a DC source. The following are the ranges for the DC voltage
supported by the unit;
Minimum: 88 VDC Nominal: 125 -250 VDC Maximum: 300 VDC
The DC supply(s) should have adequate over-current protection within the closed rack system and
comply with local or national standards applicable to the installation territory. You need wire gauge
14 to 18AWG to connect the IOLAN rack mount unit to the power source.
Note:
The equipment must be grounded for safety and to ensure ESD protection for correct
operation and protection of the internal circuitry.
AC Power Requirements
The IOLAN can be powered via an AC source. The following are the ranges for the AC voltage
supported by the unit;
Minimum: 85 VAC Nominal: 100 -240 VAC Maximum: 265VAC
You need wire gauge 14 to 18AWG to connect the IOLAN rack mount unit to the power source.
