Philips PE 1516 Mode D'emploi page 7

- dynamic : For sinusoidal load variations of 80 % from full load
to full load and a frequency of:
0.1 kHz < 0.005 2
и Wm ede &
IO iais 00S
100 kHz<0.2 Q
245 kii OZ Q
Recovery time : < 100 usec for a square-wave load variation of 80 %
from full load to full load.
By recovery time is understood the time which elapses
between the beginning of the load variation and the
moment after which the deviation of the direct voltage
remains within the limits determined by the static
internal resistance. See fig. 6.
Temperature coefficient 2 < 0.01 Wor < Wo) пак рев °C of the set value of the
output voltage between 0 and 30 V in the range of
0...35 °C. Whichever is greater applies.
Over -voltage protection : Adjustable between 3 V and 31,5 V
b. As current stabiliser
Current : 0 to 20 A, continuously adjustable with the knobs
marked "I" (coarse and fine adjustment);
fine adjustment in steps of < 15 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 <2 mA, whichever is greater applies.
Ata load variation from point E to point G in the
current-voltage characteristic (Fig. 5), the fluctuation
of the output current is < 10 mA of the set value
(internal resistance > 3 КЯ).
Ripple current SO а (at output voltage of 3 to 30 V)
PS
Temperature coefficient : < 0.05 % or < 1 mA per °C of the set value of the
output current between 0 and 20 A in the range of
0...35 °C. Whichever is greater applies.
3. Cross-over point, see Fig. 4 : Point C-D < 100 mA. This value applies for any set
output current between 0 and 20 A.
Point D-E < 30 mV. This value applies for any set
output voltage between 0 and 30 V.
4. Indication : In the case of voltage stabilisation - lamp "U" is lit.
For current stabilisation - lamp "I" is lit.
In the case of over -voltage the indication lamp "DC
failure" is lit.
