INH/FLT Characteristics

Maximum ratings:

16.5 Vdc between terminals 1 and 2; 3 and 4;

 

 

and from terminals 1 or 2 to chassis ground

 

FLT Terminals:

Low-level output current = 1.25 mA max.

 

 

Low-level output voltage = 0.5 V max.

 

INH Terminals:

Low-level input voltage = 0.8 V max.

 

 

High-level input voltage = 2 V min.

 

 

Low-level input current = 1 mA

 

 

Pulse width = 100 μs min.

 

 

Time delay = 4 ms typical

1For full scale current changes with a risetime of 20 μs, an additional 0.5% error exists in the first data point in the buffer after the change. The error percentage increases proportionally with the decrease in risetime.

2This time may be reduced by changing the default conditions of 2048 data points, however, measurement accuracy will be reduced.

3COMPatibility language is used to program the HP 663xA Series power supplies.
