It is used in heating control of various electric equipment

Control load: resistive and inductive load

There is no phase sequence relationship between main power supply and auxiliary power supply

Automatic tracking function of three phase sequence

Load voltage: 110VAC / 220VAC / 380VAC / 440VAC

Current capacity: 10 ~ 500A

Product features

*New digital chip control: precision and anti-interference greatly improved.

*Unique slow start function: it can avoid damage caused by abnormal main power supply and input signal.

*Multiple LED indicators: PWL, in, out, open, oh indicators. In case of failure, it can be eliminated quickly.

*With the indication of open circuit of main power supply and fuse fusing, SCR automatically stops output (yellow open light is on for a long time, al1 and al2 output).

*Built in temperature sensor: it can accurately detect the temperature of heat sink as fan controller and over temperature protection.

*Modular design, ultra efficient heat sink: good heat dissipation, strong structure, light weight.

*Cooling fan control; when the temperature of radiator is higher than 50 ℃, the fan starts; when the temperature is lower than 45 ℃, the fan stops. It can avoid the fan running for a long time, prolong the fan life and reduce dust adsorption. It also has the function of fan automatic test (when starting up, the fan will automatically test run for about 12 seconds)

*There is no phase sequence relationship between the main power supply and the auxiliary power supply: there is no sequence relationship between the start-up and the operation is very convenient (automatic identification of 50 Hz and 60 Hz, 100 ~ 240 V auxiliary power supply can be used)

*With three-phase sequence automatic tracking function: automatically find the balance phase to achieve the three-phase output balance, if there is a missing phase, the output will be automatically stopped, and the open light will be on.

Panel instructions

*Pl (green): auxiliary power indicator, which is on for a long time when the auxiliary power supply is powered on.

*In (green); signal input indicator, when the input signal is greater than 4mA or there is a signal, it is on when the input signal is less than 4mA or there is no signal.

*Out (green): SCR output indicator, display SCR output status, when the output is larger, the display is brighter.

*When the main power supply is open or the fuse is blown, the open light will be on for a long time. When the load is open, open will flash. At this time, SCR will stop output and al1 and al2 contacts will output. When the exception is eliminated, it will be recovered automatically.

*0h (red): SCR overtemperature indicator light, this model contains sensors, when the temperature is higher than 50 ℃, the fan will be started, and when it is lower than 45 ℃, it will be turned off. When the temperature is higher than 82 ℃, oh lamp will be on, SCR will stop output and al1 and al2 contacts will output. When the temperature is lower than 73 ℃, it will return to normal automatically.
