Description
The I4201 is a stabilised AC voltage source, made by IEMI in Bucharest and designed at the ICE research institute [1]. The ICE laboratory’s table gives its code as J 4201 [1].
ICE’s laboratory for electronic instruments for measuring electrical quantities designed all the institute’s generations of oscilloscopes, voltmeters, multimeters, signal generators, frequency meters, logic analysers, RLC bridges and stabilised AC power supplies; they went into production at IEMI or in ICE’s own microproduction workshop, and equipped industrial laboratories and production lines as well as teaching and research laboratories [1]. In the 1970s and 1980s about half of the components of measuring instruments were imported; after 1980 about three quarters were Romanian [1].
It delivers 1000 VA [2]. IEMI’s production table lists 4,325 units made in 1972–1985 [2].
Its list price, set in 1982, was 7,600 lei [3].
Annex III.2.14 says it gave a stabilised AC voltage of 220 V ±1%, adjustable between 210 and 230 V, at up to 4.55 A, from mains of 190–240 V, for assembly and adjustment lines for valve or transistor equipment, adjustment lines for meters and relays, laboratory electric furnaces, and supplying or testing electrotechnical equipment under reference and rated conditions [4].
