Phase Control Thyristor T273-3200 AS ENERGITM is general purpose disc thyristor, also known as Silicon Controlled Rectifier (SCR). This is a power thyristor designed for converting and control DC and AC currents up to 3200A with frequency up to 500Hz in circuits with voltages up to 200V – 1800V (voltage class from 2 to 18). Thyristor dimensions ØDxØdxH – 112x75x26 mm (outer case diameter X contact surface diameter X case height), weight – 1200 g.

Thyristor ratings: T273-3200-2 (3200A 200V), T273-3200-3 (3200A 300V), T273-3200-4 (3200A 400V), T273-3200-5 (3200A 500V), T273-3200-6 (3200A 600V), T273-3200-7 (3200A 700V), T273-3200-8 (3200A 800V), T273-3200-9 (3200A 900V), T273-3200-10 (3200A 1000V), T273-3200-12 (3200A 1200V), T273-3200-14 (3200A 1400V), T273-3200-16 (3200A 1600V), T273-3200-18 (3200A 1800V).

The anode and cathode of the thyristor (polarity) are determined by the symbol on the case. Thyristors are in a press pack disc (capsule, tablet) housing. This SCR thyristor can be an alternative product, replacement, analog, equivalent for other types thyristors 2600A, 2700A, 2800A, 2900A, 3000A, 3200 amp in a disk package.

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 case (indicated in the parameter table) must be provided.

Thyristors SCR disc type are used in power equipment – power and control units, power regulators, converters (e.g. melting furnaces), controllers where fast switching and control of currents is necessary.
