Product Description
Technical parameter
Rated capacity (KVA): 250 KVA,
Input current (A): Correlation to the rated capacity
Input voltage (V): 380VAC+/-20% optional, 220VAC+/-20% optional
Output voltage (V): 380VAC+/-5% optional, 220VAC+/-5% optional
Phase number: Three phase single phase
Insulated strength: 2000V/1 Min does not have the puncture
Time for response: ≤ 1.5s (input fluctuation within 10%)
Efficiency: ≥ 98%
Waveform distortion: ≤ 0.1%
Working frequency (Hz): 50~60
Constant voltage precision: +/-5% adjustable
Since most of textile equipment are installed in cotton-dusty and humid environment and usually voltage regulators are required to be near textile equipment, the voltage regulator of textile equipment designed by our company makes use of the structure of sealing inner air duct board. Auto temperature test control is applied to emit heat. The whole system is moisture proof to ensure continuous and normal operation of equipment in highly humid environment. It has the features of high precision of voltage regulation, good stability and flawless protection.
