Series HB1700S and HB1701S adjustable DC voltage-stabilized sources are high
precision DC stabilized power sources whose voltage and current can be continuously
adjusted and stabilized voltage and current can be automatically transferred. The
output voltage can be selected at random in the rated scope from 0V. The current-
limiting protective point also can be selected at random and the output current can be
continuously adjusted in the rated scope. The series HB1700S is single-circuit power
source; HB1701S is double-circuit power source.
Among them:
The output voltage and current of series HB1700SB are indicated by liquid crystal
LED display.
The output voltage and current of series HB1700SC are indicated by electric meter.
The output voltage and current of series HB1700SL are indicated by LED digital
meter.
