  • Product description

    Electronic fan speed controller with ON/OFF switch | 6A | 110-240VAC | surface-mounted | IP54 | Sentera Controls | ITR-9-60-DT

    ITR-9-60-DT – Sentera Controls electronic fan speed controller with a knob and an illuminated ON/OFF switch. Controls single-phase voltage-controllable AC motors up to 6 A, powered from a 110–240 VAC network with automatic voltage detection.

    Key idea:
    Industrial-style manual controller: robust IP54 enclosure, clear knob and an illuminated switch that is visible even in the dark. Speed is set manually, without any programming.
    What it is for ITR-9-60-DT:
    This model is designed for more powerful fans (up to 6 A) – roof or duct fans in warehouses, workshops, halls or a group of fans.
    Max. motor current
    6 A
    Control
    Knob + ON/OFF switch
    Power supply
    110–240 VAC, 50–60 Hz
    Protection
    IP54, surface mounting

    Operating principle

    The controller is wall-mounted. Connect the power supply (L, N, PE) and the motor (U1, U2); the unregulated L1 output can power a three-wire motor, a damper actuator or a pump.

    Speed is changed smoothly by varying the motor supply voltage (electronic control). Us – supply voltage; the controller automatically detects a 110–240 VAC network.

    The knob sets the voltage from the minimum limit up to Us. Min. limit – 30–60 % Us (factory setting 45 %), set with an internal trimmer. A jumper on the board selects normal or fast start-up (8–10 s at full speed so that the motor starts reliably).

    Engineer's note: with an AC induction motor, reducing the voltage increases rotor losses, so the savings are lower than with an EC fan or a frequency inverter; when completely silent operation at low speed is essential, choose a transformer controller with a sinusoidal output voltage.

    Benefits ITR-9-60-DT?
    Reliable manual control with a wider than usual supply range (110–240 VAC) and an unregulated output – suitable for both workshops and warehouses.

    Main functions

    • Knob and illuminated switch – speed is set manually, and the on status is visible even in the dark.
    • Wide supply range 110–240 VAC – the controller detects the mains voltage automatically.
    • Adjustable min. limit – prevents the motor from stalling or overheating when running at too low a voltage.
    • Quick start – 8–10 s at full speed – reliable start-up even when a low speed is set.
    • Unregulated output L1 (2 A) – for a three-wire motor, damper actuator or pump.

    Where is it used?

    • Workshops, garages, warehouses
    • Ventilation of retail and production premises
    • Farm buildings
    • Duct, roof and axial fans with AC motors
    • 110–120 V networks (export projects)

    On-demand operation

    For the electrician.
    Simple connection, wide supply range, PE terminal.
    For the ventilation installer.
    The min. limit and start-up mode are set on site to suit the specific fan.
    For the user.
    Clear knob and illuminated switch – no settings required.

    Application guide: how it is used in practice

    Typical ITR-9-60-DT applications:

    Site What is connected Result Installer's note
    Workshop, garage Fan → U1, U2 Speed is adjusted manually as required Set the min. limit with the trimmer so that the motor always starts
    Fan with damper Damper actuator → L1 The damper is powered together with the fan L1 load – up to 2 A
    Motor with difficult start-up Quick start (jumper) For 8–10 s the motor runs at full speed, then switches to the set speed Useful when a low speed is set
    Continuously running ventilation Supply to L (without OFF) The fan always runs; only the speed is changed The OFF position is available only on 1.5 A and 3 A models

    How to select the controller current

    Rated current of the motor(s) Recommended model
    up to 1.5 A ITR-9-15-DT (1.5 A)
    1.5–3 A ITR-9-30-DT (3 A)
    3–5 A ITR-9-50-DT (5 A)
    5–6 A ITR-9-60-DT (6 A) ← this model
    6–10 A ITR-9100-DT (10 A)
    Rule: controller max. current ≥ motor rated current (see the motor nameplate). The starting current is already accounted for by the manufacturer; no additional margin is needed. When connecting several fans – motors of the same type – add up their rated currents.
    When to choose another solution: sensor (0-10 VDC) or Modbus control needed – EVS-1 / EVSS1 series; for an EC fan – an EC potentiometer; for a three-phase motor – a three-phase transformer controller; for a motor with TK contacts – the ITRS9 series.

    Pros

    • Power supply 110–240 VAC with automatic detection
    • Knob and illuminated ON/OFF switch
    • Adjustable min. limit
    • Quick start mode
    • Unregulated L1 output (2 A)
    • IP54 enclosure

    Cons / limitations

    • No 0-10 VDC input and no Modbus
    • Only for single-phase voltage-controllable motors; not suitable for EC fans
    • Operating temperature up to +35 °C
    • OFF position only on 1.5 A and 3 A models
    • No TK protection – for that choose ITRS9-60-DT
    • The output voltage is non-sinusoidal – some motors may hum audibly at low speed

    Safety and installation notes

    • Installation and connection must be carried out by a qualified electrician with the power disconnected.
    • Always connect the protective earth (PE).
    • Check that the motor is suitable for voltage control and that its rated current does not exceed 6 A.
    • Terminal layout differs depending on the model – wire according to the diagram of the specific model.
    • Intended for indoor use only (up to +35 °C).

    Quick selection guide

    6 A
    110–240 VAC
    Knob + ON/OFF
    IP54
    Suitable when you need:
    • manual speed control for a fan up to 6 A;
    • a robust IP54 enclosure in plant rooms;
    • a 110–240 VAC supply.
    Check before use:
    • the motor rated current and whether it is voltage-controllable;
    • whether an OFF position is required (only on 1.5 A and 3 A ITR-9 models);
    • the ambient temperature (up to +35 °C).
    Important reminder: ITR-9-60-DT does not control EC fans or three-phase motors.

    FAQ

    Is it suitable for 110–120 V networks?
    Yes, supply 110–240 VAC, voltage detected automatically.
    What is quick start for?
    To ensure the motor starts reliably: for 8–10 s it runs at full speed, then switches to the set speed.
    Can several fans be connected?
    Yes, provided their total current does not exceed 6 A.
    How does it differ from ITRS9-60-DT?
    ITRS9-60-DT has TK protection, NO/NC remote control inputs and a 230 V alarm output.
    Can it be controlled by a 0-10 V signal?
    No, the EVS-1 or EVSS1 series is intended for that.
