Single-Cycle Variable Time Base
With single-cycle variable time base (VTBS)
control, at 50% power, power is on one cycle, and
off one cycle. At 25%, it is on for one cycle and
off for three. Under 50%, the unit is not on for
more than one consecutive cycle. Over 50%, the
unit is not off for more than one consecutive
cycle. This model will work with a linear voltage
input, a 4 to 20mA input or a potentiometer
input.
Phase angle control (control Type P) is infinitely
variable inside the sine wave. This provides a
variable voltage and/or current output. This
option includes soft start and line voltage
compensation. This model will work with a linear
voltage input, a linear current source input or a
potentiometer input. This is single-phase only.
Alarms not available on phase angle models.
Models: DC _ _ - _ _ S _ - _ _ _ _

With variable time base control, the power
controller automatically adjusts the time base
and output power with respect to process input.
Accelerated life testing verified that the variable
time base control significantly reduces
expansion and contraction of the heater element.
This extends heater and SCR life while
improving the process temperature control. You
save money on heaters, down time and
maintenance.
