Controller selection guide

1. Product classification
1) Dimming module. The basic principle of the dimming module is that the microprocessor (CPU) controls the opening angle of the thyristor, thereby controlling the average amplitude of the output voltage to adjust the brightness of the light source

2) Switch module. The basic principle of the switch module is to control the switch of the power source by the relay output, thereby controlling the light source.

3) Input module. The basic principle of the input module is to accept passive contact signals

4) Sensor interface module. Used to connect sensors such as illuminance detection, presence detection, and motion detection

2 Design and selection points

1) Selection of switch module

(1) For lighting circuits that require switch control, a control module with the following functions should be used.

① AC power supply: incoming single-phase AC220V or three-phase AC380V, outgoing single-phase AC220V.

② The control function can be set through network software and self-learning function.

③ With system clock function.

④ It can set its network terminal function through software.

⑤ The logical relationship (AND, OR) can be set through software.

⑥ The interlock function of the relay can be set by software.

⑦ After the power is off, the relay status can be set when the call comes.

⑧ The microprocessor can also detect the operating temperature inside the switch module.

(2) The specifications (outgoing circuit and capacity) of the switch module should be determined according to the lighting circuit, capacity and control method in the controlled area.

2) Selection of dimming module

(1) For lighting circuits that require dimming control, a dimming module with the following functions should be used.

① AC power supply: incoming single-phase AC220V or three-phase AC380V, outgoing single-phase AC220V.

② The control function can be set through network software and self-learning function.

③ With system clock function.

④ It can set its network terminal function through software.

⑤ Each circuit has overload and overcurrent protection. The dimming module should be able to prevent damage to the light source due to the increase of the external main power supply voltage, and be able to control the input voltage value of the main power supply, thereby limiting the high voltage output.

⑥ It should be possible to ensure that the brightness of the light source is not changed abruptly, but is dimmed in a gradually increasing and decreasing manner.

⑦ Should be able to suppress the interference of higher harmonics.

⑧ Multiple dimming scene preset values ​​can be stored in the dimming module. All data to control the dimming of the lamps stored in the EEPROM memory will not be lost due to power failure, and the dimmer can still restore its original working state after the power failure returns to normal.
