Power Supply Specifications

I/O Models

The power supply for a desktop IOLAN I/O model must meet the following requirement:

zOutput between 9-30V DC and a minimum of 600mA current.

z20 AWG wire.

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 applicable to the installation territory. You need

wire gauge 20 to 22 AWG to connect the IOLAN rack mount unit to the power source.

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

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

Note: The maximum load for the Relay channel is 1A @ 30VDC or 0.5A @ 120 VAC.

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

operation and protection of the internal circuitry.

Note: WARNING

Before servicing this product ensure the power source has been disconnected. For dual input

or dual power supply models, ensure both sources have been disconnected.

Note: WARNING

Before servicing this product ensure the power source has been disconnected. For dual input

or dual power supply models, ensure both sources have been disconnected.
