| The TE300 is designed
for general purpose three phase applications where a resistive load or
infrared heaters are involved. Typical applications include paint drying
(car industry), metallurgy, plastics, food sector and environmental temperature
control.
The TE300 is controlled by an analogue
signal which is selectable for DC current or voltage. A 5V user voltage
allows local control by a potentiometer. The TE300 can be used to control
non standard three phase voltages by using an optional auxiliary supply
input. |
The TE300 is easily integrated into
a control system because of its compact size, simplicity of wiring and
DIN rail mounting.
The TE300 has, in addition to the
standard burst firing and single cycle firing modes, an Advanced Single
Cycle mode. This mode allows a complete number of half cycles switching
for the non firing period and a complete number of full cycles switching
for the firing period. This mode reduces the annoying visual flickering
when controlling short wave infrared elements. With advanced single cycle
firing, the cycle time is reduced compared with normal single cycle operation.
This is advantageous when phase angle firing is not acceptable and zero
crossing is required. |
