FEATURES
TRIPLE OUTPUT
Operates as three separate power supplies. Each has floating
output and is completely isolated from the other two.
ONE 4-6.5 V (1760A) or 2-6.5 V (1761 & 1762) SUPPLY
Durable 0-to-5 amp supply is ideal for use with most digital
logic circuitry. Adequate current capacity for extensive circuitry.
TWO 0-30V (model 1760A), 0-35V (model 1761), or 0-60V
(model 1762) SUPPLIES
“A” and “B” supply are continuously variable over their
respective voltage ranges with coarse and fine controls. Each
supply has a 2A (3A model 1761) current capacity.
UNIQUE TRACKING FEATURE
The “A” and “B” 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 (model 1760A), 0-70V (model 1761), or 0-
120V (model 1762) SUPPLY
Series tracking feature doubles output voltage capability and
allows use of “A” and “B” supplies combined as one supply.
SINGLE 0-30V, 4A (model 1760A), 0-35V, 6A (model
1761), or 0-60V, 4A (model 1762) SUPPLY
Parallel tracking feature doubles output current capability and
allows use of “A” and “B” supplies combined as one supply.
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.
