CS-10 PORTABLE CURRENT SUPPLY
GENERAL
The CS-10 Portable Current Supply is designed to be a convenient source of current in areas without rectifiers or
other power sources. The instrument output is selectable from zero to ten amperes. The range is selected by
adjusting the range switch. It is intended primarily for temporary drains in connection with the cathodic protection
of underground piping. It can also be a convenient source of current for testing insulating joints with a compass,
determining the extent of a CP area, locating shorts and testing casings.
PRECAUTIONS
The CS-10 can only be used in non-hazardous (unclassified) locations because it can supply current and
voltages above those allowed in hazardous (classified) locations.
LOAD LIMITING CIRCUITRY
The CS-10 is capable of supplying currents in excess of 10 Amps for very short periods of time, draining the batteries
rapidly, (less than 10 minutes). To keep the output at an acceptable level the CS-10 circuit incorporates a current
limiter for the protection of the regulating circuit and the batteries. A feature of the current limiter is the ability to
detect whether or not the CS-10 is limiting the current through the circuit or the load is limiting the current through
the circuit. In order to let the operator know when the CS-10 is limiting the current, the Limiting Indicator L.E.D. was
incorporated on the front panel. When the CS-10 is limiting the current through the load the Limiting Indicator L.E.D.
is off. When the load is limiting the current through the circuit, the Limiting Indicator L.E.D. is on continuously.
LOW VOLTAGE LOCK-OUT
The Limiting Indicator L.E.D. has a second duty. It is to warn when the internal battery of the CS-10 has fallen below
9-volts. Since the batteries in the CS-10 have an increasing chance of shorting when they are discharged beyond
a safe point, the Low Voltage Lock-out is activated to keep this from happening. When the Low Voltage Lock-out is
reached there are two things that occur. First, the power to the Output Terminals is cut. Second, the Limiting
Indicator L.E.D. is activated. In order to distinguish between a Current Limiting condition and the Low Voltage LockOut condition, the Limiting Indicator L.E.D. will start flashing. The Low Voltage Lock-Out can only be reset when the
CS-10 is turned off for 15 seconds and turned back on. At this point in time, it is recommended that the batteries be
recharged immediately or use an external power source.
HEAT
This type of equipment, under high loads, will build up high temperatures rapidly. Caution should be used to prevent
damage to the CS-10. Operator should avoid direct contact with the panel after high output operation or after
prolonged use.
The CS-10 will heat up in hot weather when currents approaching 5 or more amperes are delivered to a load. The
transistor that controls the current is mounted on an aluminum heat sink. The panel of the CS-10 should face away
from the sun to reduce heat input. For more than short use, the interrupter can be used to further reduce the heat
effect if the current drain is high and extends the battery life.
The panel on the CS-10, gets hot and stays hot in the higher output ranges. USE CAUTION!
