3 phase supply
Air Handling Unit Controller



  • System:- 3 phase 4 wire 400 V AC, 50Hz +/- 15%.
  • Contact Rating: 3pole 16A contactor for compressor
  • 25 Amp MCB for compressor outputs,
  • Temperature Sensor: Thermistor Sensor NTC 10K @ 25°C Metal Body with Clamp.
  • Temperature Sensing Range: 0.0°C to 50.0°C.
  • Indications: AC ON indication for AC1, AC2 and AC3 .
  • Fault indication for AC1, AC2 and AC3.
  • Frequency:-50 Hz / 60 Hz range (±5 Hz)
  • Measured Parameters:-
    1] Voltage (Volt) Phase – Phase measured. (RMS)
    2] Unbalance Voltage measured Phase – Phase Unbalance measured.
    3] Current (Amps) Compressor1, Compressor2, Heater, Blower (3Ph 4 w).
    4] Room Temperature.
  • Protection:- 1] Over Voltage Protection (Settable)
    2] Under Voltage Protection (Settable).
    3] Over Load Protection (Settable).
    4] Under Load Protection (Settable).
    5] Unbalance (Settable)
    6] Reverse Phasing (Settable)
    7] Phase Failure Protection (Settable)
    8] High pressure (potential free input) (AC1/AC2)
    9] Low pressure (potential free input) (AC1/AC2)
    10] AHU Door Open (potential free input) (Blower/Master controller)
  • Auxiliary Power:- No External power is required (Draws power from the voltage signal Inputs)
  • Accuracy :-
    1] Volt 0.25% rdg ± 1 dgts.
    2] Current 0.25% rdg ± 1 dgts.
  • Communication Output :-

  • Environmental:-
    1] Working Temp : 0 to 55° C
    2] Storage Temp : 10 to 70° C
    3] Relative humidity : 0 – 95 % non-condensive
  • Controls up to 3 Compressors and a Blower.
  • Protects the compressor with the advanced Proton Motor Protection Unit (MPU) from unhealthy conditions like Under Load, Over Load,
  • Under Voltage, Over Voltage, Single Phasing, Voltage Unbalance, and Current Unbalance.
  • Main Controller with 16 X 2 LCD Display protects the 3 phase blower from unhealthy voltage and current conditions.
  • Main controller communicates with MPU via RS 485 Modbus and displays the data sensed by the MPU.
  • Accurate sensing temperature by precise temperature sensors.
  • Time sharing for compressors to share load equally.
  • Continuous display of Room Temperature, Voltage and Current drawn by compressors, and Faults if any.
  • Data logging of faults occurred in on Main Controller.
  • Sequencing of comp. for equal run hours, site selectable.
  • Automatic Timer mode operation if Room sensor fails.
