Power Supply Specifications

highest voltage at some point, in which case the unit will switch to it. No power loss will 
occur during a switch over.

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.

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.

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

The Battery Return input terminals of the IOLAN can support either Isolated DC return (DC-I) 
or Common DC return (DC-C). 
You need wire gauge 12 to 18AWG to connect the IOLAN rack mount unit to the power source.

The equipment must be grounded for safety and to ensure ESD protection for correct 

operation and protection of the internal circuitry.
