SINGLE-ELEMENT THYRISTOR POWER BLOCK WITH WATER COOLED HEATSINK
Characteristics:
• single-element thyristor power module with water cooled heatsink;
• water cooling.
Application:
• rectifiers, inverters, power supplies,
• DC power controllers,
• power contactors,
• soft-starts.
Options:
• clamping in K-1 (photo 1);
• camping in K-2 special option (photo 2);
• camping in K-5 special option (photo 3);
• thermal protection;
• RC system;
• fuse.
Selection of power blocks:
Depending on the load of power block there are used different semiconductors. Size of the applied semiconductor is specified in Table 1.
Working conditions:
Single-element power blocks with water cooling are assigned to work in power electronic inverter systems:
• temperature of cooling water on entry: 50C do 300C for temperature of ambient air not lower than -100C;
• atmospheric pressure: 860hPa – 1060hPa;
• cooling water: resistivity not lower than 5x105 Ω•cm, pH: 5 – 8 and hardness not higher than 80mg CaO/dm3
