TRIPLE OUTPUT
Operates as three separate power supplies. Each has floating
output and is completely isolated from the other two.
ONE 4 TO 6.5 V (2 to 6.5V model 1761) SUPPLY
Durable 0 -to-5 amp supply is ideal for use with most digital
logic circuitry. Adequate current capacity for extensive circuitry.
TWO 0-30 VOLT (0-35V model 1761) SUPPLIES
"A" and "B" supply are continuously variable over their
respective voltage ranges with coarse and fine controls. Each
supply has a 2 amp (3 amp model 1761) current capacity.
UNIQUE TRACKING FEATURE
The two 0-to-30V (35V model 1761) supplies can be operated so
that the "B" supply tracks the "A" supply. Outputs can be strapped
for two positive voltages with a common negative, two negative
voltages with a common positive, or one positive and one negative
with a neutral common.
SINGLE 0-60V (0-70V model 1761) SUPPLY
Series tracking feature allows use of "A" and "B" supplies as
one 0-to-60V, 2 amp (0-70V, 3 amp model 1761) supply.
SINGLE 0-30V, 4A (0-35V, 5A model 1761) SUPPLY
Parallel tracking feature allows use of "A" and "B" supply as a
0-to-30 (0-35V model 1761) V supply with a 4 amp (6 amp model
1761) current capacity (through "A" output terminals).

FEATURES

CONSTANT VOLTAGE OR CONSTANT CURRENT
The "A" and "B" supplies provide regulated dc voltage
output or regulated dc current output. Crossover is smooth and
automatic.
LED DISPLAY
Two large, easy-to-read LED 4-digit displays monitor
output voltage or output current of all three supplies. Use of
two meters allows simultaneous current and voltage metering
when using "A" and "B" supplies in tracking operation. Good
visibility in bright or low light.
LABORATORY QUALITY
Excellent regulation, low ripple.
PRE-REGULATOR
Limits internal dissipation for higher reliability and
efficiency.
ISOLATED OUTPUT
Either polarity may be floated or grounded.
OVERLOAD PROTECTION
Fully adjustable current limiting (from 5% to 100% of
maximum output current) for "A" and "B" supplies protects
circuit under test and the power supply.
REVERSE POLARITY PROTECTION
Prevents damage to power supply from external voltage of
reverse polarity.
