Power thyristor module MT4-400-44-D AS ENERGITM in an international standard package, 400A 4400V.
Used to convert DC and AC currents up to 400 ampere, with a frequency of up to 500 Hz on circuits with voltages up to 4400 volt (44 class).
Thyristor modules MT4-400-44-D are in a standard package D: base dimensions 77x150 mm, housing height – 84 mm, weight – 4.1 kg. Two-position module is a monolithic construction of two semiconductor thyristors: type thyristor-thyristor. Module connection diagram MT4-400-44-D – common cathode.
Series (ratings) of thyristor modules: MT4-400-38-D (400A 3800V), MT4-400-40-D (400A 4000V), MT4-400-42-D (400A 4200V), MT4-400-44-D (400A 4400V).
- Main terminals are at the top of the case and are numbered 1, 2, 3;
- Control terminals are marked on the diagram as G1, G2;
- Additional cathodes are marked on the diagram as K1, K2;
High thermal cyclic resistance and reliable operation of low-frequency thyristor modules MT4-400-44-D when switching high currents is achieved due to their design features and stable parameters of galvanic isolation.
The MT4-400-44-D thyristor modules have a clamp-on design that provides easy mounting and good contact with the cooler for heat dissipation. Several modules can be mounted on one cooler without additional insulation, which significantly reduces the overall dimensions of the assembly. Between the module and the heat sink (heat sink) it is recommended to use a thermally conductive substrate lubricated with thermal paste.
Our modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.
Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.
The final price for thyristor / diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
