400V 220V Small High Frequency 3 Phase Transformers Copper Winding Over - Current Protection

Gerneral

BK series machine tool control transformer is suitable for circuit of 50~60Hz, voltage up to 500V, usually applied as power supply for machine tool electrical appliances, local lightings and indicator lamps.

Working conditions

1.Ambient air temperature: -5°C~+40°C, the highest monthly mean temperature should not exceed +30°C; 
2.Altitude for installing place should not exceed 1000m; 
3.When the ambient air temperature is +40°C, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is + 25°C, and condensation on the product surface caused by temperature change should be taken into consideration.

Main technical characters

1. Input voltage: rated voltage ±10% 
2. Output voltage: rated voltage +5% (no load) 
3. Efficiency: ≥95% 
4. Waveform distortion: no additional waveform distortion 
5. Function: indication of input voltage, output voltage and current. 
6. Protection: over-current protection 
7. Can operate itself without anybody attending for a long term 
8. Insulation resistance: ≥50MΩ 
9. Electric strength: no breakdown or flashover phenomenon under power frequency sine voltage of 2000V for 1min 
10. Overload capability: for 1min under two times of rated current
