Elgar CW-M Series
NUMERIC DISPLAY.
This large, four-digit display, located in the voltage
cluster, is a digital voltmeter that measures and displays the power supply’s
output voltage. If the power supply is operating, but the output power is turned
off, then this meter displays the voltage that the output will assume when it is
turned on.
VOLTAGE MODE LAMP.
This lamp, located directly over the numeric
display, indicates that the power supply is operating in the constant output
voltage mode. This is the most common operation mode used. If the output
current rises above the level set by the current program level, this lamp turns off
and the CURRENT MODE lamp turns on.
VOLTAGE
Knob.
This large, multi-turn knob, at the right side of the voltage
cluster of controls, allows you to easily select the desired power supply output
voltage.
SET OVP.
This is a screwdriver accessible, multi-turn adjustment located
directly under the display. To define a maximum output voltage, first turn the
adjusting screw fully clockwise. Set the output voltage to the desired trip point.
Then, slowly, turn the adjustment counter-clockwise until a fault is generated,
turning the output off.

CURRENT/FREQUENCY CLUSTER
These six controls and indicators, located in the center of the front panel, are
used to select and display the CURRENT and FREQUENCY.
MEAS/PROG Switch
.
This switch selects which current measurement is
sent to the meter. If the meter has been set to display current, and this switch
is set to MEAS, then the measured output current is displayed. If this switch is
set to PROG, then the selected current limit point is displayed.
CURR/FREQ Switch
.
This switch selects the type of quantity to be
displayed. Selecting
CURR displays the selected current, either MEAS or
PROG. Selecting FREQ displays the operating frequency.
Numeric Display
.
The large, four-digit display in the current/frequency
cluster shows the measured quantities described above.
CURRENT MODE Lamp
.
This lamp, located directly over the numeric
display, indicates when the output current has reached its selected limiting
value, i.e., the power supply is operating in the constant current mode.
CURRENT Knob
.
A large,
multi-turn knob allows you to set the point of
inception of the constant current mode.
FREQUENCY Knob
.
A large, multi-turn knob allows you to set the operating
frequency.
