Phase control thyristors KP600A-(70...85) AS ENERGITM are general purpose power disc thyristors, also known as Silicon Controlled Rectifier (SCR). They are designed to convert and control DC and AC currents up to 600A with frequency up to 500Hz in circuits with voltages up to 7000V – 8500V (voltage class from 70 to 85). Thyristor dimensions ØDxØdxH – 74x47x26 mm (outer case diameter X contact surface diameter X case height), weight – 0.47 kg.

Thyristor ratings: KP600A 7000V, KP600A 7200V, KP600A 7400V, KP600A 7600V, KP600A 7800V, KP600A 8000V, KP600A 8200V, KP600A 8400V, KP600A 8500V.

The anode and cathode of the thyristor (polarity) are determined by the symbol on the case.

For cooling during the operation of power thyristors they are mounted with coolers (heat sinks). Depending on the amount of heat generated and the working conditions of the semiconductors, either natural air flow cooling or forced cooling can be used.

When assembling, the necessary clamping force Fm specific for each type of thyristor package (indicated in the parameter table) must be provided.

Thyristors can be manufactured for use in temperate, cold and tropical climates. Thyristors of the disc type KP are used in various power converters (e.g. melting furnaces) where fast switching and control of currents is necessary.

Specifications and parameters, datasheets PDF, dimensions, drawings, case diagrams thyristors, recommended coolers are listed below.

Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide quality declaration and certificate of conformity.

Heat sinks for power disc thyristors:

Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.

Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.

See for more information about coolers: "Water Heatsink SS series", "Air Heatsink SF series", and also "Air-heatsink" and "Water-heatsink".

I'm Gizem, I'm a chemical engineer. I'm interested in making ceramic stuffs as a hobby. Would you please give some explanation about my questions below;
1) If I only mix SiO2 and Fe2O3 (3:1), can i get a suitable product without using other components?
2) Can i use water as fastener? or would you suggest me another fastener?
3) At which temperature should i mix them?
Thank you for your interest, Kind Regards

Hello, Gizem. The mass of ceramic is produced by grinding and mixing with water of different components: clay, feldspar, sand, kaolin. The proportions of these materials are different percentages, depending on what and with what characteristics you need to get a ceramic mass.
Each manufacturer of ceramic mass has its own recipes and its own raw materials, which are available in its region.
There are also books on ceramics that specify the chemical composition and approximate recipes for ceramic masses.
