Description
1
Enable
(input)
High = RUN = +5V to
+15V
Low = OFF = 0V
The
Enable
function turns the output
section of the power supply ON and
OFF. When the power supply is
enabled, current is delivered to load
as programmed via
Ip)
,
Pin 7. Rise times resulting from
Enable
are approximately 25msec.
2 N/C
3
Interlock
(input)
Open = OFF
Connect to GND = RUN
The
Interlock
function can be
connected to external interlock
switches such as door or overtemp
switches.
4
GND
Referred to (-) output of power
supply.
5
Vout Monitor
:
(output)
0 – 10V = 0 – Vout
max
*
The output voltage of the supply can
be monitored by
Vout Monitor
.
6
Iout Monitor
(output)
0 – 10V = 0 – Iout
max
The output current of the supply can
be monitored by
Iout Monitor
.
7
Ip)
:
(input)
0 – 10V = 0 – Iout
max
The power supply output current is
set by applying a 0-10V analog signal
to
Ip)
.
8 N/C
9
GND
Referred to (-) output of the power
supply.
10,11
+5V @ 0.5A
(output)
Aux5V power supply for user.
Up to 0.5A output current capability.
12
-15V @0.5A
(output)
Auxiliary -15V power supply for user.
Up to 0.5A output current available.
13,14
+15V @0.5A
(output)
Aux15V power supply for user.
Up to 0.5A output current available.
15
Gnd
Referred to (-) output of the power
supply.
TABLE 1: LDD-100/150/250 Interface
* If maximum compliance voltage is less than 10V,
Vout Monitor
will read output
voltage directly. If maximum compliance voltage is greater than 10V, then
Vout Monitor
will be scaled such that 0-10V = 0-Vout
max
.
