H811

The H811 is a stabilized AC/DC voltage source, a hybrid integrated circuit made in Romania by ICCE (CCSIT-CE) and listed in the Agenda radioelectronistului (2nd edition, 1989) in group 8.1 „Surse de putere c.a./c.c.” (AC/DC power supplies) of the family „Surse de putere” (power supplies) [1]. Its codes (H811 and H811R) are in the Variants table.

The code is printed „H 811 (R)”; it is read here as two codes, H811 and H811R, because the 1st edition of the Agenda (1983) writes the „H 821 (R)” of this table as „H821; H 821 R” [2]. The book does not say how the two versions differ.

The table prints the H 811 (R), H 812 and H 813 next to one common description, „Sursă de tensiune stabilizată c.a./c.c.” [1]; it does not say how the three circuits differ.

The table gives no parameters or drawing. In it, the first two digits of every code repeat the numbers of its family and group (here 8.1) [1].
