Triac controller for proportional control
of electric heating
TTC25 is a proportional controller for electric heating with automatic voltage
adaption. TTC25 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.
TTC25 can control both symmetrical Y-connected 3-phase heaters and
symmetrical or asymmetrical Delta-connected heaters.
TTC25 is only intended for electric heating control. The control principle
makes it unsuitable for motor- or lighting control.
TTC25 is intended for DIN-rail mounting.
Mount TTC25 on a DIN-rail in a cabinet or other enclosure.
Mount TTC25 vertically with the text right side up.
Protection class: IP20.
Ambien temperature: 0 - 40°C
N.B. TTC25 emits approx. 45W of heat at full output which must be
dissipated.
Supply voltage (fig 1)
Terminals L1in, L2in and L3in.
Supply voltage: 210-255 or 380-415V AC
3 phase, 50 - 60 Hz with automatic voltage adaption.
Maximum current 25A/phase.
N.B. The supply voltage to TTC25 should be wired via an all-pole switch
with a minimum contact gap of 3mm.
N.B. TTC25 must be earthed.
Load (fig 1)
Terminals L1out, L2out and L3out.
Resistive 3-phase heater without neutral.
Maximum load: 3300W/phase at 230V phase - phase voltage (25A).
5750W/phase at 400V phase - phase voltage (25A).
Minimum load: 530W/phase at 230V phase - phase voltage (4A).
920W/phase at 400V phase - phase voltage (4A).

Installation

Wiring
INSTRUCTIONS
Main sensor and external setpoint (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 made using
switch 1.
Limiting sensor (fig 7)
Terminals 5 and 6. Low voltage. Not polarity sensitive.
When running room temperature control the supply air temperature can
be limited to a maximum and/or a minimum. The limiting sensor is placed
in the supply air duct after the heater.
Choice of function is made using switches 2 and 3. Choice of limiting
temperatures is made on potentiometers Min and Max.
N.B. As limiting sensor TG-K360 must be used.
