Thyristor controller for proportional control of
electric heating
CTR80 is a proportional controller for electric heating with automatic
voltage adaption. CTR80 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.
CTR80 can control both symmetrical Y-connected 3-phase heaters
and symmetrical or asymmetrical Delta-connected heaters.
CTR80 is only intended for electric heating control. The control princi-
ple makes it unsuitable for motor- or lighting control.
CTR80 is intended for DIN-rail mounting.
Technical data
Protection class IP20
Ambient temperature 0...40°C
Installation
Mount CTR80 on a DIN-rail in a cabinet or other enclosure.
Mount CTR80 vertically with the text right side up.
N.B. CTR80 emits approx. 150W of heat at 80A 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 80A/phase.
N.B. The supply voltage to CTR80 should be wired via an all-pole switch
with a minimum contact gap of 3mm.
N.B. CTR80 must be earthed.

Load
Terminals L1out, L2out and L3out.
Resistive 3-phase heater without neutral
Maximum load: 18400W/phase at 400V phase - phase voltage (80A).
Minimum load: 1100W/phase at 400V phase - phase voltage (5A).
Main sensor and external set-point (figs 2-5)
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.
