Features of BK and JBK3 Series Control Transformers

Electrical Specification

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.

  • Input voltage: rated voltage ±10% 

  • Output voltage: rated voltage +5% (no load)

  • Efficiency: ≥95% 

  • Waveform distortion: no additional waveform distortion 

  • Protection: over-current protection 

  • Insulation resistance: ≥50MΩ 

  • .Electric strength: no breakdown or flashover phenomenon under power frequency sine voltage of 2000V for 1min 

Working Conditions

  • Ambient temperature: -15°C~+40°C 

  • Altitude: <2000m

  • Relative humidity: <90% 

  • Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer’s insulation seriously, also explosive or corrosive medium is not allowed.
