Technical specifications for automatic voltage regulator (1 Piece) NO SPECIFICATIONS RESPONSE (Complied Or Not Complied) 100% full copper coil single-phase AC voltage regulator, air cooling, input 145-255V AC output 220V ±4% AC High Accuracy voltage stabilizer Power: 10kVA Input: 160-240V output: 220 -4% High accuracy full-automatic AC voltage stabilizer; Control system with linear integrated circuit, and drive the contact voltage regulator to start regulating by controlling the servo motor, Provided with delay, over-voltage, under-voltage, over-current and so on protection function to ensure the safety of the power supply; No waveform distortion, stable output voltage, less electric consumption and can work continuously. Excellent quality of output voltage, no transient electricity lost phenomenon when the electricity supply is not interrupted, which ensure the domestic computer and the electric appliance with memory function can work safely and reliably. Wide input voltage range, strong load adaptability, the 220V and 110V can be regulated output at same time. With the over-current protection when input, and the under-voltage, over-voltage protection when output, it can work normally no matter attended or not. With two indicators for input and output voltage. Novel style, elegant appearance, hanging installed, convenient usage, with two output choice of voltage regulating or direct output; Nurturing Every Learner-s Potential Users can set the voltage stabilizer in direct output state when it is in the season of stable electric supply, the voltage stabilizer will not consume electricity at this time, which is economic and convenient. Suitable for families, factories, schools, industrial and mining enterprises, research institutes, laboratories, etc. Features Input voltage range: 145V ~ 255V Stabilize accuracy: 220V ± 4%, 110V ± 4% Under voltage protection: 184V ± 4 Overvoltage protection: 246V ± 4 Input voltage range: 160V ~ 240V Speed regulator: 90% Withstand Voltage : 1500V / 1min Maximum rated current 40 (10KVA) Single phase If a Tender Security shall be required, the amount and currency of the Tender Security shall be KSHS. 300,000.00 VALID FOR 150 DAYS FROM THE TENDER OPENING DATE.
