FEATURES
Uses integrated circuits, sil-
icon transistors and diodes,
and an SCR. All the advan-
tages of solid state construc-
tion are utilized, including:
Dependability-reliability
No warm up time or stab-
ilization delay
Ruggedness
Compact size
Protects load and instrument
against overload.
Curr
ent
limit is fully adjustable from
approximately 2.5
mA
to 2
A. The power supply auto-
matically shuts down and
the OVERLOAD lamp lights
if the preset current limit is
exceeded. After clearing the
cause of the overload, sim-
ply push the set/reset button
to restore normal operation.
Permits setting current limit
without disturbing external
load connections or output
voltage settings: does not

quire
application of short
circuit to output terminals.
Simply
push the set/reset
button and adjust the
cur-
rent limit while reading the
setting on the current meter.
Continuously adjustable over
entire range with a single
control; no range switching
required.
Divided into four ranges.
Fully regulated output at all
current levels.
Allows output voltage and

multaneously without

overload protection to pre-
vent damage from incorrect

prevents the voltage level
control from exceeding

Standby mode disconnects
power
supply from load
without disturbing voltage
or current control settings.
On-off switch is combined
with voltage level control to
assure voltage setting of
zero when unit is turned on.
Lights to indicate at a glance
that the unit is turned on.
Power supply’s rectifier in-
put voltage increases in pro-
gressive steps as output
voltage setting is increased.
Improves efficiency; less
power is converted to heat
at low voltage operation.
Permits referencing the posi-
tive or negative output to
any external dc potential or
ground.
Protects against accidental
damage from reverse polar-
ity connection to external
power source.

is
used, units may be stacked.
All controls are
identified

operation helps prevent op
erator
mistakes that might
damage equipment.
