DOER Power Tech., with a strong and wide manufacturing bases to accommodate for most specific requirements.
SCR Type Static Voltage Stabilizer
The SCR type Static Voltage Stabilizer is the optimal electric voltage stabilizer, the design principle of it comprises buck-boost transformers, compensator transformers, SCRs and driven circuit, ensuring a fast, continuous, smooth and very stable output voltage. In many countries, power supply demand is considerable, giving rise to large voltage fluctuation and surges in the utility power supply, failure to ensure the incoming mains voltage is stable and clean can often lead to higher cost equipment repair.
With an experience of more than 13 years in the industry, our DSCR series static voltage stabilizer can deliver a desirable voltage value to meet various application demands in voltage accuracy of +/-2% to optimal of 1%. DOER DSVS series IGBT static voltage stabilizer are designed and manufactured with new technology to prevents undesirable voltage fluctuations to enter into your electrical appliances.
- SCR electronic design
- Being able to accommodate wide input voltage swings of in excess of 30%
- delivering voltage accuracy on the output of 2% to optimal 1%
- No moving parts (except for axial fans for cooling), reducing maintenance times
- surge arrestor: Class II4P 40KA, to protect loads against high spikes and transient voltage
- independent phase control
- Buit-in Auto Bypass: has an internal bypass system that ensures load to the mains utility in case of overload or stabilizer in malfunction.
