DESCRIPTION

1-2

This

power

supply,

Figure

1-1.

is

completely

transistorized

and

suitable

for

either

bench

or

relay

rack

operation.

It

is

a

compact,

regulated.

Con

stant

Voltage/Current

Limiting

supply.

The

output

voltage

can

be

continuously

adjusted

throughout

the

output

voltage

range.

The

power

supply

is

fully

pro

tected

from

overloads

by

a

fixed

current

limit

which

is

set

by

means

of

an

internal

adjustment.

The

cur

rent

limit

circuit

permits

series

and

parallel

connec

tion

of

two

or

more

supplies

when

greater

voltage

or

current

is

desired.

1-3

Either

the

positive

or

negative

output

terminal

may

be

grounded

or

the

power

supply

can

be

opera

ted

floating

at

up

to

a

maximum

of

300

volts

off

ground.

1-4

A

single

meter

is

used

to

measure

either

out

put

voltage

or

output

current

in

volts

and

milliamps,

respectively.

The

voltage

or

current

range

is

selec

ted

by

the

switch

on

the

front

panel.

was

inspec

ted

and

found

to

be

free

of

mechanical

and

electri

cal

defects.

As

soon

as

the

instrument

is

unpacked,

inspect

for

any

damage

that

may

have

occurred

in

transit.

Save

all

packing

materials

until

the

in

spection

is

completed.

If

damage

is

found,

proceed

as

described

REPACKAGING

FOR

SHIPMENT

2-23

To

insure

safe

shipment

of

the

instrument,

it

is

recommended

that

the

package

designed

for

the

instrument

be

used.

The

original

packaging

mate

rial

is

reusable.

If

it

is

not

available,

contact

your

local

Hewlett-Packard

field

otfice

to

obtain

the

materials.

This

office

will

also

furnish

the

the

nearest

office

to

which

the

can

be

shipped.

Be

sure

to

attach

a

to

the

3-3

OPERATION

3-4

The

power

supply

can

be

operated

as

a

single

unit

(normal

operation),

in

parallel,

or

in

series.

The

output

of

the

supply

can

be

floated

up

to

300

volts

off

ground.

3-6

To

select

a

constant

voltage

output

turn

on

the

supply

and,

with

no

load

connected,

adjust

the

VOLTAGE

controls

for

the

desired

output

volt

age.

To

check

the

current

limit,

connect

an

ex

ternal

ammeter

across

the

output

of

the

supply,

turn

the

VOLTAGE

controls

fully

clockwise,

and

observe

the

reading.

The

current

limit

is

factory

adjusted

in

excess

of

the

current

rating

of

the

supply.

If

the

existing

current

is

not

compatible

with

the

anticipated

load

requirements,

the

limit

can

be

changed

as

outlined

in

the

following

para

graphs.

3-7

CHANGING

CURRENT

LIMIT

3-8

The

current

limit

can

be

varied

by

adjusting

resistor

R50,

located

on

the

printed

wiring

board.

This

adjustment

procedure

is

described

in

Para

graph

5-63.

The

range

of

the

current

limit

control

R50

is

as

follows:

Model

Current

Limit

Range

6213A

800

-

1700mA

6215A

300

-

540mA

6217A

180

-

300mA

The

current

limit

is

normally

adjusted

to

a

value

far

in

excess

of

the

current

rating

of

the

supply

to

prevent

the

deterioration

of

line

and

load

regulation.

Therefore,

if

for

any

reason

the

current

limit

is

adjusted

so

that

the

output

current

is

close

to

this

value,

the

performance

will

not

meet

the

published

specifications.

3-9

CONNECTING

LOAD

3-10

Each

load

should

be

connected

to

the

power

supply

output

terminals

using

separate

pairs

of

connecting

wires.

This

will

minimize

mutual

coup

ling

effects

between

loads

and

will

retain

full

ad

vantage

of

the

low

output

impedance

of

the

power

supply.

Each

pair

of

connecting

wires

should

be

as

short

as

possible

and

twisted

or

shielded

to

re

duce

noise

pickup.

(If

shield

is

used,

connect

one

end

to

power

supply

ground

terminal

and

leave

the

other

end

unconnected.)

3-11

If

load

considerations

require

that

the

output

power

distribution

terminals

be

remotely

located

from

the

power

supply,

then

the

power

supply

out

put

terminals

should

be

connected

to

the

remote

distribution

terminals

via

a

pair

of

twisted

or

shielded

wires

and

each

load

separately

connected
