Phase Control Thyristor T223-250 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 250A with frequency up to 500Hz in circuits with voltages up to 1800V – 2600V (voltage class from 18 to 26). Thyristor dimensions ØDxØdxH – 42x19x26 mm (outer case diameter X contact surface diameter X case height), weight – 100 g.
Thyristor ratings: T223-250-18 (250A 1800V), T223-250-20 (250A 2000V), T223-250-22 (250A 2200V), T223-250-24 (250A 2400V), T223-250-26 (250A 2600V).
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 220A, 230A, 240A, 250 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.
Specifications and parameters, datasheets PDF, sample technical passport, dimensions, outline drawings, case diagrams thyristors, recommended coolers are listed below.
Our company provides a quality guarantee for power scr thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport, certificate of conformity.
The final price for phase control disc thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
