TTC40F
Triac controller for proportional control
of electric heating
TTC40F is a proportional controller for electric heating with automatic
voltage adaption. TTC40F pulses the whole load On - Off. The ratio
between On-time and Off-time is varied 0 - 100% to suit the prevailing
heat demand. The current is always switched at zero phase angle to
prevent RFI.
TTC40F can control both symmetrical Y-connected 3-phase heaters
and symmetrical or asymmetrical Delta-connected heaters.
TTC40F is only intended for electric heating control. The control prin-
ciple makes it unsuitable for motor- or lighting control.
TTC40F is intended for DIN-rail mounting.
Installation
Mount TTC40F on a DIN-rail in a cabinet or other enclosure.
Mount TTC40F vertically with the text right side up.
Protection class: IP20.
Ambient temperature: 0 - 40°C
N.B. TTC40F emits approx. 70W of heat at full output which must be
dissipated.
Wiring
Supply voltage
Terminals L1in, L2in and L3in.
Supply voltage: 210-255 or 380-415V AC
3 phase, 50 - 60 Hz with automatic voltage adaption.
Maximum current 40A/phase.
N.B. The supply voltage to TTC40F should be wired via an all-pole switch
with a minimum contact gap of 3mm.
N.B. TTC40F must be earthed.

Terminals 1and 4. Low voltage. Not polarity sensitive.
N.B. Terminals 2 and 3 are internally connected and are used to simplify
wiring when using external setpoint.
N.B. Choice of internal or external setpoint is done using switch 1.
