Transfer Switches - A.T.S

Transfer Switches - A.T.S

Mechanically latched changeover switch for emnergency power and normal power changeover

Features

  • Sufficient contact open time to avoid possible arcing during changeover.
  • Contact pressure is kept constant by leaf spring and therefore no change in contact conductivity due to voltage fluctuations.
  • No operating current required after the changeover because of the mechanical latch mechanism.
  • Contacts are made from silver alloy for high resistance to burn-off.
  • Self sliding contacts clean dust and oxidation on contact each time when the contactor is operated.

ATS are designed and manufactured employing production procedures in a strict quality control

  • Low-Power Type
    Saves operating power with the instantaneously excited solenoid
  • Safety Design
    Offers safety operation implying dustproof molded resin enclosures
Standard
The entire series ATS are designed and manufactured in compliance with the most commin International Standards.
Standard Operating Conditions
  • Ambient temperature is not higher than 40°C ~ -5°C
  • Altitutd is not over 2000meter at sea level
  • Humidity L 85%~45%
The abnormal site conditions(vibration, shocks, dusty air, explosive, flammable, harmful gas, vapour, oilvapour and etc) not specified the above.
Electrical Characteristics
  • Large current capacity with small operating current.
  • Excellent performance, closing capacity-12 times as large as rated current.
  • Suitable for emergency power supply facilities.
  • Swichable control voltage(AC and DC.)
  • "On & Off" can be made by Reliable Electromagnetic Solenoid(which are employed for the transfer/changeover system)
  • Simple Operation Sequence Diagram
Mechanical Characteristics

The robust mechanical structure permits easy access to the connections and components during maintenance checkups.

  • Reliable operation using the latch mechanism.
  • Compact and light weighted Design.
  • Unprecedented minimum of dimensions
  • Simplicity for construction : handiness for inspection and maintenance.
  • Superiority of contacting capacity : new system of the movable contacting mechanism makes it stable and sturdy more against high or adnormal current.
  • Long life : No trouble will occur due to the elimination of the conductive parts, main contact enjoys long wearing by rerason of arc being directed eoward the auxiliary contact.
