Philips PE 1520 Bedienungsanleitung Seite 10

Temperature coefficient : < 0.01 % or < 1 mV per °C of the
set value of the output voltage
between 0 and 75 V in the range of
0...35°C. Whichever is greater
applies.
b. As current stabiliser
Current : 0 to 6A, continuously adjustable
with the knobs marked "I" (coarse
and fine adjustment) ;
fine adjustment in "steps" of < 4 mA.
Stability : For mains voltage variations of
+ 10 % of the nominal value the
fluctuation of the output current is
< 0.05 % of the set value or < 0.6 mA,
whichever is greater applies.
At a load variation from point E
to point G in the current-voltage
characteristic shown in Fig. 5, the
fluctuation of the output current is
< 5 mA of the set value (internal
resistance > 15 kQ).
Ripple current <2 MA zaad
Temperature coefficient : < 0.05 bor < 0.3 mA per °C of the
set value of the output current
between 0 and 6 A in the range of
0...35°C. Whichever is greater
applies.
3. Cross-over point, see Fig. 4 : Point C-D < 10 mA. This value
applies for any set output current
between 0 and 6 A.
Point D-E < 75 mV. This value
applies for any set output voltage
between 0 and 75 V.
4. Indication : In case of voltage stabilisation -
lamp ''U" is lit, in case of current
stabilisation - lamp "I" is lit.
