FEATURES
TRIPLE OUTPUT
Operates as three separate power supplies. Each has floating
output and is completely isolated from the other two.
ONE FIXED 5V SUPPLY
0-to-4 amp fixed 5 volt supply is ideal for use with most
digital logic circuitry. Adequate current capacity for extensive
circuitry.
TWO 0-24 VOLT SUPPLIES
“A” and “B” supplies are continuously variable over 0-to-24
volt range. Each supply 0.5 amp current capacity.
UNIQUE TRACKING FEATURE
The two 0-to-24 V 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 0-48V SUPPLY
Series tracking feature allows use of “A” and “B” supplies as
one 0-to-48 V, 0.5 amp supply.
SINGLE 0-24V 1 AMP SUPPLY
Parallel tracking feature allows use of “A” and “B”
supplies as a 0-to-24 V supply with a 1 amp current capacity
(through “A” output terminals).
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.
METERING
Two, easy-to-read meters monitor output voltage and
output current of the “A” and “B” supplies. Use of two
meters allows simultaneous current and voltage metering
when using “A” and “B” supplies in tracking or independent
operation.
LABORATORY QUALITY
Excellent regulation, low ripple.
LED INDICATORS
Identify mode of operation.
PRE-REGULATOR
Limits internal dissipation for higher reliability and
efficiency.
