ANALOG CONTROL
101
A COM
16 Analog signal common. Connected to the sense-
terminal when remote sense is used. Connected to
the negative output terminal when remote sense is
not used.
STATUS COM
17 Common for status signals 18, 19, 20, 21 and 22.
CV STATUS
18 Turns on when CV mode is active. (photo coupled
open collector output)
CC STATUS
19 Turns on when CC mode is active. (photo coupled
open collector output)
ALM STATUS
20 Turns on when any of the protection modes are
tripped (OVP, OCP) or if a shutdown signal is
input. (photo coupled open collector output)
OUTPUT ON
STATUS
21 Turns on when the output has been turned on.
(photo coupled open collector output)
POWER OFF
STATUS
22 Turns on when the power switch is turned off.
N.C.
23 Not connected
OUT ON/OFF
CONT
24 Turns the output on/off when (default setting) a
low TTL signal is applied. Internally, the circuit is
pulled up to +5V with 10k
Ω
resistance.
SER SLV IN
25 Series slave input during master-slave series
operation.
N.C.
26 Not connected
External Voltage Control of Voltage Output
Background
External voltage control of the voltage output is
accomplished using the MIL-26 connector on
the rear panel. A voltage of 0~10V is used to
control the full scale voltage of the instrument,
where:
Output voltage = full scale voltage × (external
voltage/10)
