HP 6268B Operating And Service Manual

Table 1-1 Specifications: Models 6259B, 6260B, 6261B, 6268B, 6269B (Continued)
LOAD TRANSIENT RECOVERY TIME:
Less than 50/Jsec is required for output voltage recovery
(in constant voltage operation) to within lOmV of the
nominal output following a change in output current equal
to the current rating of the supply or 5 amps, whichever
is smaller.

or from the maximum rated output
of that voltage above zero.)

PANEL METERS:
The accuracy of the front panel voltmeter and ammeter
is ±2% of full scale. The ranges of these meters are:
Model Model
6259B 12V,60A 6268B 50V,35A
6260B 12V, 120A 6269B 50V, 60A
6261 B 24V, 60A
TEMPERATURE RATINGS:
Operating 0 to 55'C Storage -40 to +75 C
COOLING:
These power supplies are forced air cooled. The Model
6259B is cooled by a single fan; the other models are cooled
by two fans.
RESOLUTION:
(Minimum output voltage or current change that can
be obtained using the front panel controls.)
Model Constant Voltage Constant Current
6259 B 1 m V 50mA
6260B 1 mV 100mA
6261B 2mV 50mA
6268B 5m V 30mA
6269B 5m V 50mA
OUTPUT IMPEDANCE (TYPICAL):
Approximated by a resistance in series with an inductance
as follows:
Model Model
6259B 0.05mft, IpH 6268B 0.2m£2, 1/uH
6260B 0.02m£2, IpH 6269B 0.1m£2, IpH
6261 B 0.01mS2, IpH
OVERVOLTAGE PROTECTION CROWBAR:
To avoid false tripping, the recommended trip margin
above the output voltage is 5% of the output voltage plus
2 volts for Models 6259B, 6260B, and 6261 B, and 5% of
the output voltage plus 1 volt for Models 6268B and 6269B.
The approximate crowbar trip voltage ranges are:
Model Model
6259B 2V-12V 6268B 4V-45V
6260B 2V-12V 6269B 4V-45V
6261 B 2V-23V
