      LEROY SOMER R250 AVR REGULATOR 


General Description / Specifications

Developed and manufactured by LEROY-SOMER, R-series automatic voltage regulators are transistor controlled and monitored, thereby providing excellence regulation regardless of load distortions. The voltage accuracy is +/- 0.5% in a stable state and at constant Speed. With many features fitted as standard, R-series automatic voltage regulators (other than the R230) can be upgraded with modules for parallel operation (current transformer, power factor adjustment and R726 voltage matching) and for three-phase recognition

Encapsulated in resin, R-series regulators have optimum resistance to throb and harsh atmospheric circumstances. The alternator with Shunt excitation is self excited with an R 230 voltage regulator. The regulator monitors the exciter excitation current as a task of the alternator output voltage. Very effortless in design, the alternator with shunt excitation has no sustaining short-circuit capacity. LEROY-SOMER offers an unparalleled range of excitation systems without slip rings or revolving field brushes, the main systems being ACC, with capacitor excitation for low-power, single-phase applications, Shunt, for three-phase and standard single-phase applications AREP and Shunt+PMG for three-phase applications when discriminating protection or short-circuit capacity are required.

The R230 AVR features the following modification capabilities. (Please note that no adjustments should be made prior to careful consultation of the alternator installation and maintenance manual)
>Alternator output voltage adjustment
>Stability adjustment


General Characteristics

>Voltage regulation: around ± 0.5%.
>Voltage supply/sensing range 85 to 139 V (50/60 Hz)
>Rapid response time (500 ms) for a transient voltage variation amplitude of 20%
>Voltage setting P1
>Stability setting P2
>Power supply protected by 8 A fuse, Slowblow action (tolerates 10 A for 10 s)
>Frequency: 50 Hz with ST3 jumper - 60Hz without ST3 jumper
>Factory-set underspeed protection P3


Applications
