*Phase regulating voltage output

Advantages: applied to fixed resistance,variable resistance load and lighting regulation.Continuous output without interruption.

Disadvantages: harmonic wave will be generated when triggered.

*Zero-crossing regulating power output

Advantages: no harmonic wave,the power factor which can reach the highest without half wave component.

Disadvantages: only applicable to the constant load, and the ammeter will be shaking when output.

1.Three phase three wire input is adopted in the main circuit without phase sequence requirements.

2.SCR is wall-mounted,and vertical installation can achieve the best heat dissipation effect.

3.SCR is high-current product,please keep in mind that terminals (R.S.T) and (U.V.W) should be locked tightly,otherwise it will cause heating of terminals and result in SCR burning.

4.When the body temperature exceeds 85℃,SCR stop output.When temperature drops to 70℃,SCR return to work(show"H" and flicker when over-temperature.

5.When the load is not in use,disconnect the control signal to make the SCR output be zero,and then cut off the power supply of the main circuit.

6.Operating Environment: please use in a well-ventilated environment free from direct sunlight or thermal radiation and corrosion or flammability.

1.The main circuit adopts three-phase three-wire input without requirement for phase sequence.

2. Applicable load: Constant impedance, IR far-infrared Ray, UV lamp, etc.

3. For Y connection load, the center must be connected with zero line, if not so, relative equilibrium of three-phase must be required, or SCR will be burned.

4. SCR is a wall type, vertical installation ensures excellent heat dissipation.

5. SCR is a product with big current, please keep in mind that terminals (R.S.T) and (U.V.W) shall not be lock tightly, or SCR will be burned by terminal heating.

6. During the use of module, when the load power is more than 15KW, it's best to be equipped with proper radiator, and heat conducting silicon grease should be coated between radiator and SCR backboard with wind cooling.

7. Module protection: Please use semi-conductive fast fuse for load over current.
