Product Description

ACU133 ATS Controller is suitable for No Neutral Position 3-Stage ATS. It can accurately detect 2-way-3-phase voltage and judge voltage abnormal (such as over voltage, under voltage, over frequency, under frequency, lack of phase and phase reverse), then control ATS to transfer. After abnormal of 1# power, the controller will send signal to start the genset. The controller has remote communication, remote control and parameter configuration functions via LINK port communication.


ACU133 controller can detect 2-way voltage (2-way mains or 1-way mains and 1-way gens) and control ATS.

1) Suitable for 3-phase 4-wire, 2-phase 3-wire, single phase and 3-phase 3-wire (requires hardware modification)  AC systems;

2) "1# in main, 2# for standby" transfer priority;

3) Measure and display 2-way 3 phase Voltage and Frequency:


1#                              2#

Phase voltage (Ua, Ub, Uc)        Phase voltage (Ua, Ub, Uc)

Line voltage   (Uab, Ubc, Uca)    Line voltage   (Uab, Ubc, Uca)

Frequency    Hz                 Frequency    Hz

 4) Over/under voltage, over/under frequency, lack of phase and phase reverse detect function;

5) LED display work status;

6) Auto/Manual mode. In manual mode, ATS can be switched by pressing front panel button;

7) 1 breaking compulsorily port;

8) Manual test and Timing test function;

9) Applicable for 2 isolated neutral line.

10) Close output can be set to Pulse or Continuous output;

11) Any one way of A phase voltage is normal, the controller and ATS can normally work. When 2-way power and volts are abnormal at the same time, if voltage of A phase is normal, ATS will automatically transfer to Breaking (Middle) Position;

12) Parameter setting: parts of parameters can be adjust from front panel; all can be adjust via LINK port(with M58 adaptor) by using computer software;

13) Digitization adjustment of parameters (abandon simulation adjustment, enhanced reliability and stability);

14) Strong anti-electromagnetic interference ability, can be used under complex electromagnetic interference environment;

15) Modular design, self extinguishing ABS plastic shell, pluggable terminal, compact structure;

16) Three installation ways: panel built-in, internal 35mm slideway and internal screw mounting.
