Power Supply Specifications

Rack Mount Models (except Electric Utility models)

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 appl icable 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 grou nded for safety and to ensure ESD protection for correct

operation and protection of the intern al circuitry.

AC power rack mount units come with standard power cords, specific to your country, that should be

used to power the IOLAN unit.

The MDC model comes with standard power cords, specific to your country, that should be used to

power the IOLAN unit.

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-240 V (50-60 Hz) or

nominal DC range of 125V-250V.

DHV - Dual Redundant High Voltage power inputs with no minal AC range of 100V-240V (50-

60Hz) or nominal DC range of 125V-250 V. 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.

The IOLAN can be powered via a DC source. The following are the rang es 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 standard s 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 grou nded for safety and to ensure ESD protection for correct

operation and protection of the intern al circuitry.

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 po wer source.
