OCP – Overcurrent Protection

Functions

See functions description on page 22.

Setting Parameter

☞

OFF: OCP

function

is inactive

Continuous current limiting (current regulation)

☞

ON: OCP

function

activated

The output is deactivated as soon as current limiting has been
active for the specified

DELAY

time.

☞

The selected text parameter does not become active until the
<

ENTER

> key is pressed!

Settings

The procedure is described in principle in chapter 4.7.

The

OCP

display and a related

text parameter appear in the
setup function window.

Path to Selection of the OCP Text Parameter

Note

Load current for the output capacitor is also acquired by the
current regulator, and is limited to a value of Iset



Ioad. If the

OCP

function has been activated and

ISET

and

DELAY

have been set to

low values, the output may even be deactivated if output voltage
is increased. For this reason,

DELAY

must at first be set somewhat

higher than the resulting output voltage response time.

Functions

See functions description on page 23.

Settings

The procedure is described in principle in chapter 4.7.

The

DELAY

display appears in

the window for the setup
function, along with a related
numeric parameter [t].

Pon – Specifying a Power-On Status

Functions

•

Use automatic KONSTANTER configuration after power on.

Setting Parameters:

☞

rSt: (RESET

) Factory default settings are utilized

☞

SbY: (STANDBY

) Same settings as prior to shutdown, power

output remains inactive (

)

Disabled panel controls are re-enabled after mains ON.
From firmware version 4.003 onwards:
Disabled panel controls remain blocked even after mains ON.

☞
