Thyristor controller for proportional control of
electric heating
TTC63F is a proportional controller for electric heating with automatic
voltage adaption. TTC63F 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.
TTC63F can control both symmetrical Y-connected 3-phase heaters
and symmetrical or asymmetrical Delta-connected heaters.
TTC63F is only intended for electric heating control. The control
principle makes it unsuitable for motor- or lighting control.
TTC63F is intended for DIN-rail mounting.
Installation
Mount TTC63F on a DIN-rail in a cabinet or other enclosure.
Mount TTC63F vertically with the text right side up.
Protection class IP20
Ambient temperature 0...40°C non condensating
N.B. TTC63F emits approx. 120W of heat at 63A and full output which
must be dissipated.
Wiring
Supply voltage
Terminals L1in, L2in and L3in.
Supply voltage: 400 V AC +/- 10% 3 phase, 50...60 Hz
Maximum current 63A/phase.
N.B. The supply voltage to TTC63F should be wired via an all-pole switch
with a minimum contact gap of 3mm.
N.B. TTC63F must be earthed.

Load
Terminals L1out, L2out and L3out.
Resistive 3-phase heater without neutral
Maximum load: 14500W/phase at 400V phase - phase voltage (63A).
Minimum load: 1100W/phase at 400V phase - phase voltage (5A).
Main sensor and external set-point (figs 2-6)
Terminals 1 and 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.
