FEATURES
FULLY SOLID STATE 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
CURRENT LIMITING/ Protects load and instrument
OVERLOAD against overload. Current
PROTECTION 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.

without disturbing external
load connections or output
voltage settings; does not re-
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.
O-50 VDC
Continuously adjustable over
entire range with a single
control: no range switching
required.
O-2 AMPS
Divided into four ranges.
Fully regulated output at all
current levels.
DUAL METERS Allows output voltage and
current to be monitored si-
multaneously without switch-
ing ranges from current to
voltage. Both meters have
overload protection to pre-
vent damage from incorrect
range selection.

current limit setting.
0-25V and 0-50V ranges pro-
vide maximum meter resolu-
tion. A mechanical stop
prevents the voltage level
control from exceeding ap-
proximately 25 volts when
the O-25 V range is selected.
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.
Heavy duty S-way binding
posts for positive and nega-
tive polarity output and earth
ground.
Modem, functional design.
When more than one unit is
used, units may be stacked.
All controls are identified
and easy to read. Simplified
operation helps prevent op
erator mistakes that might
damage equipment.
