E&L has designed a series of compact, inexpensive, relia-
ble and rugged units to meet the needs of small labs, educa-
tional institutions and hobbyists. These units are available
either in kit or assembled form.

CDP-01
THE ALL-PURPOSE GEN-
ERAL DESIGNER
Here is all you need for a
wide variety of c rcuit work.
From CMOS Logic, TTL, Lin-
ear IC's to simple A/C de-
sign. A central work area
covered by Velcro" Loop
Material gives you complete
freedom in attaching dif-
ferent units to the in-
strument. Terminals are
labeled for easy identifica-
tion and the unique dual cur-
rent ' imiting concept saves
preclous IC's from burn- out.
The power supplies have the
capacity (.75A and .25A) to
do any reasonably sized job
that ' its on the working sur-
face. Each CDP-01 comes
with a hard backed SK- 10
Socket. Available in kit
(CDP-01K) or assembled
(CDP-01A) form at either
115V or 230V

 In addition to the above supplies, the CDP-01 provides
+24/-24V dc ( unregulated) fused internally at 1/4 amp. Also
available on the front panel are two connections to one of
the low voltage secondary windings — nominally 10V ac. The
primary fuse will blow in the event of a short.

CONTROLS:
(1)— Off On Switch ( with integral light)
(1)—Low/High current limiting switch.
(1)— Uncommitted linear 10K slide pot with center tap
(detent)
(2)— Uncommitted slide switches — SPDT (1/2 amp @
125 V dc)

Connectors: (25) BP- 22 — Insulated solderless bread-
boarding pins.
(1) SK- 10 with permanent backing.
(1)—BNC Connector
(6)-5 Way Binding Posts

Miscellaneous: Center portions of panel covered with  
Velcro Loop Material for attachment of external components.
(3) Fuses — ( 2) 1/4A and ( 1) 3/4A Slo-Blo.
(For additional Velcro to attach custom
components, use V-04.)
