Queensland two crystal flat-general SCR KP500A / 1600V

KP type general thyristor normal operating conditions and installation conditions 1, self-cooling and air-cooled ambient temperature -40 ℃ ~ 40 ℃, water-cooled ambient temperature 5 ℃ ~ 40 ℃ 2, relative humidity ≤85%; 3, non-corrosive gases in the air and dust damage the insulation; 4, pressure 85Kpa-106Kpa; 5, no severe vibration or shock; 6, if the special occasions, should make the appropriate test to prove reliable before use; 7, forced air cooling: wind speed ≥6m / s, air temperature ≤40 ℃; 8, water cooling: flow ≥4L / min, pressure: 0.2 ± 0.03Mpa, water resistivity ≥20kΩ · cm, PH value 6-8. Notes 1 selection, use, maintenance personnel need to understand the principles of the product, performance, usage, precautions. Improper use of the device in order to avoid damage and economic loss; 2, select the appropriate current and voltage should be left margin, not too small; 3, must have the line pressure overcurrent protection measures; must have equalizing when both series and parallel connection flow measures; 4, the own device when the die: a, radiator cooling effect must be proven to meet your needs; b, radiator tops do cleaning; c, countertops coated conductive grease (paste); d , die-polar and polar radiator consistent; e, the die table diameter concave station must be compatible with the heat sink table diameter; f, axis positioning accuracy and then apply a predetermined pressure.
