POWER BLOCK – photo 1
POWER BLOCK – photo 2
SINGLE-ELEMENT DIODE POWER BLOCK
WITH RY HEATSINK.
Characteristics:
• single-element diode power module
with double-sided cooling in heatsink – RY;
• natural cooling.
Application:
• rectifiers,
• power supplies.
Options:
• standard option (photo 1),
• with black anodized heatsink (photo 2),
• special option (photo 3),
• thermal protection,
• RC system,
• fuses,
• forced cooling.
Selection of power blocks:
Depending on the load of power block there are used different semiconductors. The size of applied semiconductor is specified in Table 1.
Working conditions:
Single-element power blocks are assigned to work
in powerelectronic inverter systems:
• temperature of ambient air: -100C – +400C;
• atmospheric pressure: 860hPa – 1060hPa;
• relative humidity not higher than 80%
for temperature 400C;
• cooling air without aggressive chemical agents
nor conductive dust.
