Advanced Features

The high level thresholds act similar to the OVP and OCP features (but use a different mechanism) while the 2 low level thresholds provide you with additional protection features: Under Voltage and Under Current Protection (UVP and UCP).

ARM

The trigger mechanism

To ARM a Power Module means to tell the Power Module to store new output settings values (Vset, Iset, OVset, OCset and polarity) for future use without modifying its output.

When a Power Module is armed, new output settings values are stored and do not change the state of the output of the Power Module.

The stored values are used by the trigger mechanism in several of its operating modes, as described below.

Any other output control command sent to the Power Module (e.g. output on/off, disconnect relays open/close, etc.) will un-arm the Power Module and use the stored Vset and Iset values when updating its output. Any stored polarity change is ignored.

Every Power Module of the XMP 2600 can receive a trigger and perform a programmed action.

Trigger events can be supplied to the Power Modules using the hardware TRIG connector at the back of the XMP 2600 mainframe (applied simultaneously to all the Power Modules in the mainframe) or a software command. The software trigger command can produce a global trigger (applied simultaneously to all the Power Modules) or a trigger for a specific Power Module.

The following paragraphs describe the various operating modes of the trigger mechanism.

Set output to stored values

While operating in this mode, a received trigger will take the Vset, Iset and polarity values programmed while the Power Module was armed and use them to update the state of the Power Module’s output.

Let’s say that module No. 1 is currently providing 10V with a current limit of 5A and we would like it to change its output in response to a trigger. We will use the following commands sequence:

ARM 1

→

arm the Power Module

VSET 1,15

→

value stored, output does not change

ISET 1,10

→

value stored, output does not change

TRIG 1,0

→

program the trigger operating mode

When a trigger is supplied to the Power Module (using either the hardware connector or a software command) the Power Module is un-armed and its output changes to the stored values.

Toggle the output state on/off

In this operating mode, each trigger supplied to the Power Module causes its output to change state:

If the output of the Power Module was off then it is turned on. If the output of the Power Module was on then it is turned off.

To select this operating mode, send the following command: TRIG <ch>,1
