TTC 25 • Triac controllers

Triac controller for DIN-rail mounting with setpoint adjustment for controlling 3-phase electric heating batteries, it is necessary to connect an external sensor to the controller. This can be an NTC sensor as well as 0-10V.

Application

  • Electric heating batteries

Specifications

  • Possible to connect 230 V or 400 V 3-phase electric heaters
  • Maximal load: 9,5 kW (230V) or 16,5 kW (400V)
  • Room temperature control: for slow temperature changes, works as P-controller (P = 2K)
  • Supply air temperature control: for rapid temperature changes, works as PI-controller (P = 20K, reset time = 6 min)
  • Settable cycle time: 6 to 60 s
  • Min/max limit possible: 0 to 60°C

Mounting

  • DIN-rail

Accessoires

  • Duct temperature sensors, type TG-K330
  • Room temperature sensors, type TG-R530
  • Min/max temperature sensors, type TG-K360
  • Room temperature sensors for external setpoint, type TG-R430

Technical data

  • Supply voltage : 230V AC or 400V AC, 3-phase. Automatic adaptation
  • Current : minimum 3 A - maximum 25 A
  • IP 20
  • Proportional band : 2K fixed (room control) / 20K fixed (supply air temperature control)
  • Reset time : 6 minutes, fixed (supply air temperature control)
  • Pulse period : 6 to 60 s
  • LED indication on the controller when the output is active
  • Two inputs for NTC sensors, one main sensor and one min/max limit
  • One input for an external 0-10V signal
  • Setpoint : selectable, either internal or external

Function

  • The controller pulses the entire power output ON/OFF. The controller utilises time-proportional control, the ratio between On-time and Off-time is varied to fit the prevailling heating requirement (exemple ON = 30s and OFF = 30s gives 50 % output power).

Settings

  • Setpoint range : 0 to 30°C, the choice of sensor determines the controller setpoint range
  • Minimum limit : 0 to 30°C
  • Maximum limit : 20 to 60°C
  • Cycle time : 6 to 60 s
