: < 0.01 % or <1 mV per °C of the set value of the
: < 40 mA.
: < 0.05 % or < 1.5 mA per °C of the set value of the
1515
: < 2 mQ for slow changes from no load to full load.
: For sinusoidal load variations from 80 % of full load
to full load and a frequency of:
0.1 kHz < 30 mQ
0.5 kHz < 90 mf
1 kHz < 50 mQ
10 kHz < 30 m2
100 kHz < 30 mQ
250 kHz < 50 mQ
: < 100 msec. for square-wave load variations from
80 to 100 %.
The recovery time is the time which elapses between
the beginning of the load variation and the moment
at which the deviation of the direct voltage remains
within the limits determined by static internal
resistance (see fig. 4).
E'S;
output voltage between 0 and 30 V in the range of
OR DC
Whichever is greater applies.
: Adjustable between 3.5 and 35 V.
: - 0 to 12.5 A, continuously adjustable with the knob
marked "I"!
- resolution < 15 mA.
: - For mains voltage variations of +10 % of the
nominal value, the fluctuation of the output current
is < 0.1 % of the set value or < 5 mA.
Whichever is greater applies. |
- At a load variation from point E to point G in the
current-voltage characteristic (fig. 3), the
fluctuation of the output current is < 12 mA of the
set value.
m.s
output current between 0 and 12.5 A in the range
of 0.400
: - Point C-D < 40 mA. This value applies for any set
output current between 0 and 12.5 A.
- Point D-E < 40 mV. This value applies for any set
output voltage between 0 and 30 V.
: - In case of voltage stabilization lamp "U" is lit
- In case of current stabilization lamp "I" is lit
- In case of over-voltage lamp "DC failure" is lit
- Volt- and ammeter switchable with buttons 12.5 V,
30 V and 12.5 A.
