Semiconductor regulator for the alternator 28V, type PH - 28V/1
The regulator for the alternator 28 V with minus regulation is a circuit made on the ceramic board and produced with SMT technology. The ceramic board is pluged in the metal case and sealed with the epoxy resin. The output with the flat hollow A 6,3 mm is made of the cable with the cross-section 0,75 mm2.
If the regulator doesn't work, it must bear the temperature +120°C for time 2 hours.
The regulator of the voltage is determined as a part of the power supply's system with alternators 28V, to 50 A. The lifetime of the regulator is 4000 hours. It doesn't practise by the type test.
The regulator has to pass the test of the durability for 2000 hours in the formation with the carbons and the alternator TPP 00009253. 14/91 type 443 113 516 660. This test is standard for review of the durability. The requirement for the lifetime is executed, when the alternator in the formation with the regulator passes the test of the durability.
