Noise Supressor-Watford Control - Used Laboratory Equipment and New Lab Instrument Supplies, UK

Transient Noise suppressor and isolation transformers - ISO TRAN 12H

The Iso-Tran consists of a transient noise suppressor / isolation transformer to provide transverse mode and common mode noise attenuation when there is no requirement for voltage stabilisation.

The units are supplied in attractive ventilated sheet steel enclosures to IP20. Models with ratings up to and including 13 Amperes are supplied with an output circuit breaker, 1.5m input cable and 3-pin output socket complete with plug. All other models above 13A are supplied suitable for “Hard Wiring” to terminals within the enclosure.

• Input / Output Voltages 200–240V single phase/340–415V three phase
  
  
• Other voltages to order.
  
  
• Frequency 47 to 65 Hz
  
  
• Efficiency 98%
  
  
• Surge Rating Capable of sustaining:
  
  

  10 times rated current 1 sec

  5 times rated current 20 secs

  3 times rated current 2 mins

  
  
• Environment operates –15 degC to +45 degC, derate by 2% for each degC up to a max of 60 degC. Maximum altitude 1000m, derate by 2.5% for each additional 500m. Suitable for indoor tropical use up to 95% RH.
  
  
• High Energy spike attenuation. A 50-microsecond energy pulse of 3000V peak is attenuated to a harmless 20V low frequency ripple. Shorter duration pulses are attenuated to a greater extent.
  
  
• High frequency Noise. High attenuation RFI filter is incorporated.
  
  
• Earth to Neutral. The output is fully isolated and by earthing the output neutral common mode noise is virtually eliminated. Do not earth equipment at any other point.
