Features
Controller Features
Mode: Switches
between 1 and 3 phase outputs.
Parallel Operation:
9000CS/2, 13500CS/3, 18000CS/3 systems use two to four 4500CS
chassis in parallel operation. The individual chassis must be connected
using the system interface cable supplied with the system.
Controller:
Programmable controller front panel assembly.
Output Relay:
Standard output relay feature to isolate power source from the load.
Output On/Off:
The output relay can be used to quickly disconnect the load. A yellow
status indicator displays the status of the output relay.
External Trigger Output
or Function Strobe
An external TTL output is available which may be used to trigger other
equipment. The TTL output can be controlled by the transient
programming system. This requires the trigger mode to be set to EXT
(factory default). This can only be done over the bus using the
OUTP:TTLT:MODE TRIG command.
It can also be configured to generate an output pulse any time the
current, frequency, voltage limit or phase programming is updated. This
requires the trigger mode to be set to FSTR. This can only be done over
the bus using the OUTP:TTLT:MODE FSTR command.
The Trigger Output (Trig Out1) / function strobe is an active low
1
TTL
signal with a duration of no less than 400 usec.
Clock and Lock Mode
Enables two or more independent CS power systems to be phase
synchronized to each other. One system (-LKM) acts as the master, the
other(s) (-LKS) as auxiliaries. The –LKS units are synced to the –LKM
unit. Refer to section 3.9 for details on Clock and Lock mode.
Trigger Input
A TTL input signal may be used as an external trigger source for output
changes programmed on the AC power source transient system. This
requires the trigger source to be set to EXT. This can only be done over
the bus.

Available Options – CS Series
Output Options
-AX
Auxiliary outputs, 5 VAC and 26 VAC, 400 Hz. (Output D and E)
-LF
Low frequency option. Limits maximum output frequency to 500 Hz.
-HF
High frequency option. Increases output frequency to 5000 Hz.
Misc. Options
-L22
Locking Knob. Shaft lock screw replaces shuttle knob to prevent turning
of shuttle.
-LAN
Ethernet LAN interface connection. RJ45 connector.
Note: When installed, RS232C interface is disabled.
-LKM
Clock and Lock Master. Enables synchronizing outputs of two CS AC
sources, one acts as master.
This mode supports a frequency range of 45 to 819 Hz on standard CS
models. See section 3.9.
1 Note: Early production models may have an active high Trig Out1 polarity.
