Power Supply Specifications
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 three 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.
LDC - Dual, low voltage DC power inputs with nominal range of 24V-60V. The power supply can
be fed by either source1 or source 2 or both. When both power inputs are live, the unit
selects the input with the highest voltage. The other input is not used unless it becomes the
highest voltage at some point, in which case the unit will switch to it. No power loss will
occur during a switch over.
DC Power Requirements
HV and DHV models:
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.
LDC models:
The IOLAN can be powered via a DC source. The following are the ranges for the DC voltage
supported by the unit;
Minimum: 18 VDC
Nominal: 24-60 VDC
Maximum: 72 VDC
You need wire gauge 12 to 18AWG to connect the IOLAN rack mount unit to the power source.
AC Power Requirements
HV and DHV models;
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: 265 VAC
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.
