Option -8
Extended Temperature Range
Extension of the temperature range from standard
–40...85
°C. In the upper temperature range the output
power derating below should be observed. The modules
will provide the specified output power with free air convec-
tion cooling.
Option R
R specifies magnetic feedback from the output for closer
regulation of the output voltages of double output units.
(Standard feature for single output units and -0503- types.)
It enables the adjustment of the output voltages via the R-
input on the secondary side by an external resistor or an ex-
ternal voltage source in the range of approximative
75…105% of
Uo nom. Option R includes the trim input (see
also table:
Pin allocation), option K as well as the possibility
to operate several converters with the ouputs connected in
parallel.
Option i
Inhibit
Excludes shut down
The output(s) of the converter may be enabled or disabled
by means of a logic signal (TTL, CMOS, etc.) applied to the
inhibit pin. No output voltage overshoot will occur when the
unit is turned on. If the inhibit function is not required the
inhibit pin should be connected to Vi– to enable the output
(active low logic, fail safe).
Converter operating:
–10 V...0.8 V
Converter inhibited
or inhibit left open circuit:
2.4 V...
Ui max (<75 V)
