MODEL NUMBER IDENTIFICATION
1029C-[X]-[XXX]V-[XXX]A-IL[XXX]-R[XXX]-I[XXX]
1029C
The basic model number.
[X] The type of feedback
A - Specifies average voltage feedback. With average voltage feedback,
the controller varies the conduction angle (or ON time) of the SCRs
such that the average voltage applied to the load is proportional to
the command signal.
E - Specifies external feedback. The external feedback being
proportional to some parameter such as speed, current, etc. that is
ultimately being controlled by the action of the controller.
I - Specifies RMS current feedback. The load current is linearly controlled
with respect to the command signal.
P(XXXAMPS) - The letter P specifies power feedback and therefore the
load power is linearly controlled with respect to the command signal.
XXX equals amp level for control of power. MAX LOAD POWER =
(VOLTS)V x P(AMPS)
V - Specifies RMS voltage feedback. With RMS voltage feedback, the
controller varies the conduction angle (or ON time) of the SCRs
such that the RMS voltage applied to the load is proportional to the
command signal.
[XXX]V Operating Voltage
120, 208, 240, 277, 380, 415, 480 or 575 Vac
Note: unless otherwise specified, the controller is shipped with a
transformer that has primary voltage taps at:
240, 480 or 575 volts, 50/60 Hz.
[XXX]A Operating Current
50, 80, 120, 160, 200, 250, 300, 380, 425, 500, 600 or 750
(consult factory for 1000 & 2000 Amps)
IL[XXX] Current Limiting
Up to 105% of controller rating.
R[XXX] Run Command Signal
0/5Vdc, 4/20mA or Potentiometer
I[XXX] Idle Command Signal
0/5Vdc, 4/20mA or Potentiometer
Example:
1029C-A-480V-80A-IL75-R0/5V-IPOT
Will order a 1029C controller with average voltage feedback, rated @ 480 Volts, 80 Amps, current limit set at 75 Amps,
run command signal of 0 to 5Vdc and a potentiometer on the idle command input.
If a "SC( VVV) term is included, it implies special calibration, meaning that the controller has been calibrated for a
maximum output of (VVV) voltage rather than the rated (line) voltage. Contact factory for information.
