IReftUe* ROTATING REGULATOR The Type VD Rogutator hoe been designed to meet tho demand* of ' voltage or current characteristic* of dc machine operation. Resistors ora cut in ond out of tho exciter shunt field by the Rocking Contact sector. No sluggish, time wasting relays. ac j4fijrfloatle*t& No vibrating or sliding contacts to wear out. A small movement of the Rocking Contact sector over a curved commutator covers tho entire regu lating range. Type VD regulators are available for all dc generators. Write for Bulletin 14B6137A. VM Regulator for d omiratsa from )0 kw ot 80 mm ta 200 kw el 3000 rpm FOR LARGE GENERATORS Maximum Productivity from New Generators lArNew Efficiency from Present Installations Regulex voltage regulators incorporating auto* rnotic minimum excitation permit generator operation dose to the stability limit. .. much closer than manual operation allows. The sen* sitivity and exceptional response of the Regulex voltage regulator end associated equipment establish and maintain a safe ratio between generator load and field current. .. increase, operating limits at any given power factor load; . ... assure tho proper reactive kva division. Tho Regulex voltage regulator docs not require multiple special fields in the exciter -- may be applied to any standard shunt machine. Write for literature. a Versatile "Tools" Used in Solving Your Particular Voltage Regulation Problem For special industrial and military regu- latinf systems, added flexibility is obtained by using magnetic and electronic ampUflert. These components tupplemenl but do not replace the Regulex rotating am* pltfler in most applications. The magnetic amplifier is used primar* iiy'vybere raversiblo output from the am plifier is not required. Special exciter design U eliminated in such applications. The shock-proof characteristics of tho magnetic amplifier make it particularly adaptable to military voltage control. Eloctronle amplifiers are used only on applications that require exceptionally high sensitivity. Applications ofmognetic ond electronic amplifiers for purposes other than voltage control include speod, current, ond tension, regulation. tiroes V-00 end 721 Regulators FOR SMALL GENERATORS Rocking Contact Voltage Regu lators aro availablo in two types for use on smalt ac generators with dfroct-connected oxcitens -- Typo V-00 for generators to 15? kva maximum at 3600 rpm; Type 221 for generotors to 438 kva maximum at 3600 rpm. These regulators can be modified for temperature compensation, shock mounting or other specisl re quirements. Bulletin 14B6143A gives details.

Typo B Regulator--for ac gen erators, 1000 kva at 257 rpm to 6250 kva at 3600 rpm. Typo C Regulator-.for ac gen erators from 3125 kva at 257 rpm to 25,000 kva at 3600 rpm. All have guaranteed sensitivity of plus or minus 0.6%. Writo for Bulletin 14B6035B. Atlli-CWmrri trSMrk*.
