0-5 VDC (0-100%) front panel current potentiometer set
Zout ~
point monitor output. Minimum load resistance
100Ω
10kΩ. Circuit return Pin 6 (COM).
Isolated TTL/CMOS on/off control. A high state
TTL/CMOS voltage enables the output, i.e., turns on the
Zin ~ 2.2kΩ output of the supply, and a low state or open connection
disables the output, i.e., turns off the output of the supply..
Circuit return Pin 2 (ISO RTN). See Section 3.7.
Remote voltage programming using a 0-10 VDC source.
Do not exceed 25 VDC. Circuit return Pin 4 or Pin 20 (VP
Zin ~ 20kΩ
RTN). See Section 3.5.
Remote current programming using a 0-10 VDC source.
Do not exceed 25 VDC. Circuit return Pin 23 or Pin 25 (IP
Zin ~ 20kΩ
RTN). See Section 3.4.
Fault state output. A high state (approximately +10 VDC)
Zout ~ indicates a converter, temperature or bias supply fault, and
100Ω the LED on the front panel will illuminate. Circuit return Pin
6 (COM).
Shutdown fault. This terminal goes to high state in the
event of converter, temperature, overvoltage or bias supply
fault. A 7 VDC to 13.3 VDC signal can be applied to this
Zout ~
pin to shutdown the output of the unit. An 8 VDC minimum
100Ω
output signal is provided into a 10 kΩ minimum load, in the
event of an internally generated shutdown. Circuit return
Pin 6 (COM). See Section 3.9.
Output voltage monitor. 0-10 VDC equals to 0-100% rated
Zout ~
voltage. Minimum load resistance 10kΩ. Circuit return Pin
100Ω
6 (COM).
Voltage programming return. Used with J1-9, J1-15 or
J1-21 and must be referenced to Pin 6 (COM) circuit
Zin ~ 10Ω
common.
1 milliamp current source for remote voltage programming
~ 10.8V using resistance. 0-5k ohm resistor referenced to Pin 4 or
compliance Pin 20 (VP RTN) will program the output voltage from 0-
100%. See Section 3.5.
