Servo Voltage Stabiliser

Sylvan Electronics offers a Servo Voltage Stabiliser to counter the problem of fluctuations in supply voltage to electrical equipments. These servo controlled voltage stabilisers are high speed electro-mechanical regulators that provide constant output voltage at pre-determined level. They yield an accurate and constant voltage. Stability in the output is compared with a stable reference amplified suitably and fed for corrective action (i.e., to lower or raise the output voltage as required). A digital circuit is used to give above required commands. All equipment incorporates latest technology and design for outstanding performance. Salient features: high response, low inertia, rugged AC servo motor; virtually zero wave form distortion; very low internal impedance; no phase shift, nil effect on load power factor; high quality raw materials used – prime grade lamination and high purity electrolytic copper wires/strips; fast correction rate up to 70 V/sec; quick response time 10 mS (half a cycle); special circuit to ensure constant output on DG sets; industrial grade design for indoor tropical use; conforms to IS: 9815 specification, machine wound variacs with special carbon brushes for enhanced life; and voltage adjustment on output. Applications: CNC machines, hotels, medial equipments, R&D institutions, motor loads, defence application, induction heating, telecommunication networks, industrial units, residential/office accommodation, air-conditioning plants, lighting loads, and bio medical equipment. Specifications, single phase/three phase: input voltage – 160 V-260, V – 300, V-460 V/340 V-480 V; output voltage – 230 V – 380 V/400 V/415 V; output regulation – ±1% or 0.5%/±1% or 0.5%; efficiency – better than 95%/better than 97%; frequency – 47-53 Hz/47-53 Hz; wave form distortion – nil/nil; effect of load on power factor – nil/nil; temperature – depends on type of cooling and IS specifications; and motor – burn proof high torque AC synchronous motor.
