Advantage
1. Not need connect to +12V DC power supply. Some products require you to provide + 12V power supply, and also has precision requirements, it is great inconvenience. This product does not require.
2. Not need connect synchronization transformer (or other trigger module). Becuase of rational design, saves space for you to use, and simplifies installation and wiring. At the same time, less wiring also reduces the possibility of poor contact.
3. Many control types. You can use potentiometer to control, also can use a variety of automatic control signal (eg 4-20mA, 0-5VDC, 0-10VDC, etc.), a module has variety of control types, it is convenience. This makes your selection simple, easy stocking, avoid selection errors result in losses.
4. Has high control precision linear. Users typically ignores the parameter of observed tunable accuracy. Some products have very narrow adjustment range, for example 4-20mA control, the actual range is only 6-13mA; some even can't output 0 or maximum voltage. Such immature product is worthy of thought-provoking.
5. Adopt high quality ST big power thyristor module as the core component. High-quality products are not only user sought, and it is our credibility and life.
6. The model with "-F" is with closed loop negative feedback function. When the input voltage fluctuation or the output load changes, the module output remains constant. If customer require high stability output voltage, can use this. Related parameters: constant voltage range: 5% to 90% (input>output) / constant volatility ≤1% / constant voltage hysteresis time ≤10ms. In actual use, even if the three-phase electrical input voltage is in rapidly and significant fluctuations, the output voltage will always be able to stay steady.
Note 1. Model selection method: calculate the load current of each phase when the voltage is full, according to load type, multiply the balance factor.
Resistive load: balance factor is 3 times, such as incandescent lamp, resistance wire, oven, heating rod.
Inductive load: balance factor is 5 times, such as: transformer, coil, fan motor, pump motor.
Example: 9KW three phase 380V furnace. 9KW/3/220V*3=40, can select 50A specification.

2. Can't be used loads: home appliances (such as televisions, computers), the electrical equipment with switching power supply.

3. Can't be unloaded.

4. This product can be for the star or triangular load. When the load is star connection, if the phase imbalance, should connect the neutral wire to the center point.

5. To use product long and safely, please install the product with corresponding heat sink and fan.
