POWER switch
When turned on, the indicators POWER and either of C C and
C V light. The power switch is automatically cut off when pro-
tection (overvoltage/overcurrent/temperature) has operated.
(2)
Voltmeter
Indicates the output voltage or the preset voltage.
(3)
Ammeter
Indicates the output current or the preset current.
(4)
V O L T A G E
Control that presets voltage for constant-voltage operation.
Turn it clockwise to raise the output voltage.
(5)
CURRENT
Control that presets current for constant-current operation.
Turn it clockwise to increases the output current.
(6)
C V indicator
Indicates during constant-voltage operation.
(7)
C C indicator
Indicates during constant-current operation.
(8)
OUTPUT indicator
Red LED indicates when the output is on. The preset voltage is
available at the output terminals when this indicator is on.
(9)
OUTPUT swtich
Output switch (contactless) that turns on and off the output
electrically. When the output is on (-•-), the OUTPUT indicator
8 lights and the voltage the voltmeter is reading is output at
the output terminals and the ammeter reads the current.
#
V/l CHECK
Voltage/current check switch. A s long as this switch is
depressed, the voltmeter reads the preset voltage and the am-
meter the preset current so that you may preset voltage and
current. To check the preset voltage and current, depress this
switch when the OUTPUT switch is on.
(fj)
OVP CHECK
Overvoltage protection
level check switch. Depress this
switch and the voltmeter reads the preset overvoltage pro-
teciton level so that you may preset the level with the OVP
adjuster 12 .
@
OVP adj. control
Semi-fixed adjustment control permitting to preset the over-
voltage protection level.
n
Output terminal ( + )
Positive output terminal (red).
( Q )
Output terminal ( - )
Negative output terminal (white).
©
GND
Ground terminal connected to the frame. This is connected
also to the output terminal ( - ) normally.
Voltmeter zero adjuster
Adjuster of the voltmeter zero point. (Not for D type)
(\T) Ammeter zero adjsuter
Adjuster of the ammeter zero point. (Not for D type)
