External Voltage
Connection
The external voltage reference input must be
between 0~10V.
WARNING
Ensure the external voltage reference is stable and has
low noise. The External Voltage should be no more
than 10V.
No more than 12 volts may be used as an external
voltage. More than 12 volts may damage the load
generator.
Load on
connection
To turn a load on, an active low voltage (0-1V)
must be applied across Load On (pin 5) and GND
(pin 1), similarly an active high voltage (4-5V)
must be applied to turn a load off. The Load On
input must be TTL.
