FEATURES
0-30 VOLTS
Continuously variable over 0-to-30 volt range with coarse
and fine controls.
0-1 AMP AND 0-3 AMP VERSIONS
0 to 1 amp (1710A) and 0 to 3 amp (1730A) models
available. Each rated for continuous duty at full output
current.
LABORATORY QUALITY
Excellent regulation, low ripple.
CONSTANT VOLTAGE OR CONSTANT CURRENT
Provides regulated dc voltage output or regulated dc
current output. Crossover is smooth and automatic.
TWO CURRENT RANGES
High-Low switch selects full output (0-1A for Model
1710A, 0-3A for Model 1730A), or partial output (0-.25A
for Model 1710A, and 0-.5A for Model 1730A). Low
range improves current stability and meter res olution at
lower current values. Switch simultaneously selects range
of adjustment and corresponding meter scale.
BUILT-IN METERING
Two large, easy-to-read meters continuously monitor output
voltage and current.
LED INDICATORS
Act as pilot light and id entify mode of operation.
PRE-REGULATOR
Limits internal dissipation for higher reliability.
ISOLATED OUTPUT
Either polarity may be floated or grounded.
OVERLOAD PROTECTION
Fully adjustable current limiting (from 5% to 100% of
maximum output current) protects circuit under test and the
power supply.
REVERSE POLARITY PROTECTION
Prevents damage to power supply from external voltage of
reverse polarity.
STYLING
Modern functional styling. Configuration conserves bench
space and aids portability. Logical, convenient layout of
controls.
