2.11 MONITORING OUTPUTS

The monitor outputs give a voltage 0 - 5 V proportional to the
output current or voltage. The output current can easily be
measured without an external shunt using the CC monitor
(see fig. 2 - 6).
The monitor outputs are buffered by op-amp’s and protected
by zeners in parallel (see fig. 2 - 7). The table below shows
the impedance of the monitoring outputs. The monitoring and
the reference outputs are stable for capacitive loads up to
2 µF, for larger values a 22 Ohm resistor should be put in
series.

Note: in case of a pulsating load, the I monitor voltage will not
exactly match the output current. This is mainly caused by the
current through the output capacitors. Remote sensing will
worsen this effect.

Vmon 10 1 Ohm 4 mA
Imon 2 1 Ohm 4 mA
+12V 7 500 Ohm 25 mA
0 1 1.2 Ohm
2.12 +12V ON PROGRAMMING CONNECTOR

The +12V on the programming connector can be used for
supplying external circuits like the MASTER / SLAVE
ADAPTER. The output is current limited, but should not be
overloaded.
2.13 CC STATUS OUTPUT

The CC status output has an open output voltage of 5 V and a
short circuit current of 10 mA. This makes it possible to drive
directly: an opto-coupler, a TTL gate or a CMOS gate.
2.14 REMOTE SHUTDOWN

A voltage of +5V on the Remote ShutDown input on the
programming connector will switch off the power circuit of the
unit. In standby mode the unit consumes little power.

It is also possible to use a relay contact or a switch to shut
down the unit: connect a switch between Vref and Remote
Shutdown (pin 9 and 5).
2.15 PROGRAMMING RESPONSE TIME

The response time is measured with a step wave form at the
CV prog. input. The load is resistive. Programming from a low
to a high output voltage is nearly load independent, but
programming down to a low voltage takes more time on
lighter loads. This is caused by the output capacitors, which
can only be discharged by the load because the power supply
cannot sink current.
