5–2 Variable Period Full Wave SSR, continued…
The advantages of VPFW SSR, over conventional SSR, are sum-
marized in the following table:
Output 1 and output 2 of the TEC-9300 can be connected to the
VPFW SSR directly provided that a pulsed voltage drive output
is ordered.
Here is an example:
Three phase VPFW SSR’s are also available upon request.
5–3 Heat Only Control
An oven is designed to dry the products at 150°C for 30 minutes
and then stay unpowered for another batch. A TEC-9300
equipped with dwell timer is used for this purpose. The system
diagram is shown as follows:
To achieve this function, set the following parameters in the setup
menu.
FUNC = BASC (basic function)
IN1 = K_TC
IN1U = °C
DP1 = 1_DP
OUT1 = REVR
O1TY = RELY
CYC1 = 18.0
O1FT = BPLS
A1FN = TIMR
A1FT = ON
SELF = NONE
Auto-tuning is performed at 150°C for a new oven.
