Output on/off terminal.
On when set to LOW (0 to 0.5 V) or shorted (CF10: Lo);
Off when set to HIGH (4.5 or 5 V) or open (CF10: Lo)
On when set to HIGH (4.5 to 5 V) or open (CF10: Hi);
Off when set to LOW (0 or 0.5 V) or shorted (CF10: Hi).
External signal common for pins 5 to 9, 11 to 13, 20 to 22, 24, and 25.
During remote sensing, this is the negative electrode (-S) of sensing
input. When remote sensing is not being performed, this is connected
to the negative output.
External resistance control terminal; 5.25 V (CF07: Lo) or 10.5 V
(CF07: Hi). The maximum output current 2.5 mA.
Terminal used to control the output current with an external voltage
or external resistance.
0 to 5 V; 0 to 100% of the rated output current (CF07: Lo).
0 to 10 V; 0 to 100% of the rated output current (CF07: Hi).
Terminal used to control the output voltage with an external voltage
or external resistance.
0 to 5 V; 0 to 100% of the rated output voltage (CF07: Lo).
0 to 10 V; 0 to 100% of the rated output voltage (CF07: Hi).
External signal common for pins 5 to 9, 11 to 13, 20 to 22, 24, and 25.
During remote sensing, this is the negative electrode (-S) of sensing
input. When remote sensing is not being performed, this is connected
to the negative output.
Output current monitor.
0 to 100% of the rated output current is generated as a voltage
between 0 and 5 V (CF08: Lo) or a voltage between 0 and 10 V
(CF08: Hi).
Output voltage monitor.
0 to 100% of the rated output voltage is generated as a voltage
between 0 and 5 V (CF08: Lo) or a voltage between 0 and 10 V
(CF08: Hi).
