Multiple-output non-
programmable models
With multiple supplies in a compact
unit, the E3620A and E3630A
provide excellent performance while
saving space on your bench. Both
instruments feature a tight 0.01
percent line and load regulation and a
low normal mode noise specification
of less than 0.35 mV to ensure clean
power for precision circuitry. With a
common mode current specification of
less than 1 μA, both multiple-output
power supplies minimize the power
line current injection.
Like the single-output models in the
E3600 Series, the E3620A and E3630A
feature separate digital panel meters
so you can monitor the voltage and
current simultaneously. They also
protect your DUT against overload and
short-circuit damage.
Smooth turn-on and turn-off
transitions keep power spikes out of
your circuits. Auto-tracking permits
equal or proportional voltage sharing,
and allows control of output voltage
from one master unit. The master and
slave supplies have the same output
polarity with respect to a common bus
or ground. This operation is useful
where simultaneous turn-up, turn-
down or proportional control of all
power supplies is required.
E3620A dual-output power
supply
The 50-watt E3620A dual-output
power supply provides two 0 V to
25 Vdc outputs with the maximum
current of 1 A to satisfy most bench
requirements. The outputs are
completely independent and isolated.
E3630A triple-output power
supply with auto-tracking
feature
The 35-watt E3630A triple-output
power supply provides three DC
outputs: 0 to 6 V with a maximum
current of 1 to 2.5 A and 0 to 20 V and
0 to %20 V with a maximum current
of 0.5 A. An auto-tracking feature
lets you use one voltage control to
adjust the +20 V and %20 V outputs
simultaneously. The outputs track
each other to within 1 percent, making
it easy to adjust the power supply for
circuits requiring balanced voltages.
