The

 

HS

 

Series

 

provides

 

regulated

 

outputs

 

at

 

the

 

output

 

terminals.

 

When

 

there

 

is

 

a

 

large

 

current

 

and/or

 

the

 

output

 

cable

 

is

 

of

 

some

 

length,

 

the

 

voltage

 

at

 

the

 

end

 

of

 

the

 

cable

 

may

 

be

 

noticeably

 

lower

 

than

 

at

 

the

 

terminals.

 

The

 

converter

 

can

 

compensate

 

up

 

to

 

0.75V

 

of

 

voltage

 

drop

 

through

 

remote

 

sense

 

terminals.

 

To

 

ensure

 

accurate

 

regulation,

 

users

 

should

 

run

 

two

 

separate

 

wires

 

(twisted

 

from

 

the

 

desired

 

regulation

 

points

 

to

 

the

 

remote

 

sense

 

terminals.

 

Even

 

if

 

the

 

load

 

current

 

is

 

low,

 

users

 

should

 

still

 

connect

 

+Vo

 

to

 

+S

 

and

 

–Vo

 

to

 

–S.
