CONTROLLING THE OUTPUT USING EXTERNAL (ANALOG) SIGNALS (REMOTE)

How do I control the mode using an external signal?

$

, highlight External Mode,

!

, highlight Enable,

$

, then

%

to apply

changes and exit. This setting is not saved for power-up (PAR. 3.4.2). Select mode by applying either logic 1 or open circuit for voltage, or
logic 0 or short circuit for current, to pin 2 referenced to pin 9 of the Analog I/O port (PAR. 3.4.2).

How do I use an analog voltage to control the output (main channel)?

$

, highlight Reference input,

!

, highlight External

then

$

, then

%

to apply changes and exit . This setting is not saved for power-up. Apply ±10V signal to pin 11 referenced to pin 4 of the

Analog I/O port to control active channel (voltage or current) (PAR. 3.4.3).

How do I use an analog voltage to control the protection channel?

$

, highlight Protection Limit,

!

, highlight External then

$

, then

%

to apply changes and exit (not saved for power-up). Apply +1V to +10V signal to the following pins referenced to pin 12 of the

Analog I/O port to control limit channel from 10% to full scale: –Current Protect: pin 5, +Current Protect: pin 13, –Voltage Protect: pin 6,
+Voltage Protect: pin 14 (PAR. 3.4.4).

How do I choose between local, digital and analog control of the output?

The unit normally powers up in Local mode. Sending

a command via RS 232 or GPIB interfaces automatically puts the unit into Remote mode. Press

!

to restore Local mode. If an analog

voltage is controlling the output (see above), local control of the main channel is disabled and digital commands are not accepted.

How do I use the BOP as an amplifier?

See above to control the main channel and/or protection channel using analog signals. The

nominal (inherent) voltage gain of each model is calculated by (G

NOM-V

) = E

Onom

/ E

REF

. and nominal (inherent) current gain is (G

NOM-I

) =

I

Onom

/ E

REF

where E

REF

= 10V (see PAR. 3.4.3.1).

How do I control the gain of the BOP when used as an amplifier?

$

, highlight Reference input,

!

, highlight ExtlRefLevl then

$

, then

%

to apply changes and exit (not saved for power-up). Apply ±10V signal to pin 11 referenced to pin 4 of the Analog I/O port.

Main channel setting (SET) determines gain (G) by G = SET/10 (PAR. 3.4.3.2).

CONTROLLING THE OUTPUT USING DIGITAL INTERFACE (REMOTE)

How do I use the GPIB interface to control the power supply?
