TA4-220-400Transformer TA4-220-400 is an anode single-phase low-voltage small-sized transformer for a supply voltage of 220 V with a frequency of 400 Hz and a rated output power of 33 V *A.
It is designed to work in electrical power sources for general and special purpose electronic equipment manufactured on electrovacuum and semiconductor devices.
Anode transformers of the TA type are manufactured on rod and armored magnetic cores of a unified design, with a power from 7.5 to 357 V * A with an output voltage of the secondary windings from 6 to 355 V for load currents from 0.034 to 2.8 A.
They have several secondary windings designed for various currents and voltages, which, with serial and parallel connections, allow you to obtain all possible combinations of currents and voltages to power devices of various functional purposes.
The transformer design is designed for mounting on a metal chassis of equipment or on printed circuit boards with mixed mounting and mounting with screws.
They are produced in the all-climatic version "B" and in the version for temperate and cold climates "UKHL" according to GOST 20.39.404-81.
TA type power transformers can be operated at ambient temperatures from -60 to +85 °C and a relative humidity of 98% at a temperature of +40 ° C.
They are resistant to sinusoidal vibration in the frequency range of 1-2500 Hz with an acceleration of 20 g and shock loads with a duration of 1-80 ms with an acceleration of 100 g.
Quality category: "VP", "OS".
Technical conditions:
- acceptance of "5" OY0.471.000TU or OY0.471.029TU (depending on the applied magnetic circuit and climatic design);
- acceptance of "9" OY0.471.000TU, AG0.471.009TU.
The warranty period of storage of TA-type power transformers is 12 years from the date of acceptance by the customer, and in case of rechecking of the product - from the date of rechecking.
Minimum operating time:
- 12,000 hours - in all modes allowed by TU;
