Description: Contact voltage regulators have non-lack fidelity in waves. portable size,light weight high efficiency, convenience to use,reliability and durability in moveent. It can be widely used in the industries(such as chemical industry machine, metallurgy Instrument & appearance, machine manufature, light-industrial), seientific experimenis, public facilitise and housebold appliances to realize the aims of voltage regulation, temperature ontrol, light regulation and power controletc. Basic principle Regulator is self coupling transformer that circle ratio can beadjus-table continually. Main axes act with brush frame when regualtor brush recur tohand-whlle The circle ratio can be changed continuall when slide with grind surface of coil so that output-voltage adjust from zero to max smoothly. Main structure Cell structure single-phase 1KVA/ 2KVA regulator is regulate voltage cell constr-uction. The coil that up surface has a certain wide smooth surface fixde in the glass st-eel base, contact group brush tallied tightly with the grind surface in the action of spring stress. Running handwheel drive brush in the grind surface of coli to reguate volt-age, the normat type of cell regulator is stand,outside with safety ventation cover. Specifications: 5/8 amp max output 1000VA/2000VA Variable Voltage Regulator Input voltage: 220VAC Output voltage: 0-250VAC Condition tempurature:40 Humidity: 5% Working hours: 8 hours Digital Output Power Meter Included On/Off Power Switch is Lighted Gross weight: 6.4 KG Package size: 282522 cm Service conditions: 1. Environmental average temperature 15-40. 2. Altitude: the installation place for voltage regulator should not be more than 1000m. 3. Air relative humidity: the average humidity for the wettest month is 90% the average tempcrature is 25. 4. Cuurent and voltage wave:power voltage wave closes to sine. 5. Without the gas, smoke,chemical aggradation,dus defilcment,other explosive andcorrosive matters which can seriously effect the insulation of voltage regulator in the installation field. 6. Without badly vibration and wallow in the installation field. 7. Used indoors parallel connection is not allowed. 8. The special service conditions, which doesn' t conform to the above conditions, should be confirmed by the client and manufacturer. Maintenance: 1. During the normal operation, the regulator should be checked regularly by charcoal brush and make sure that the brush and contact parts won't be more than thewide oftwo wires. 2. Check the insutation resistance regularly (the relative humidity is 95% tesed with 500 meter), the insulation resistance between coil and base shouldn' t beless than 2mm. 3. For thre-phase regulator,please check and adjust the brush reguarly. 4. Please connect the ground line to vegulator case. After operation,turn the hand wheel pointer to "zero" place and cut off the power. Package included: 1 Contact Voltage Regulators
