Turbo Molecular Pumps TMP-LM Series

TMP-203M/MC/LM/LMC

Main Features

  1. The Power supplies, which use no battery, are the first half rack size units for turbo molecular pumps of magnetically levitated type.
  2. No maintenance is required for the power supply.
  3. The pump main body and the power supply are both compact and lightweight.
  4. An RS-232C serial interface is supplied as standard.
  5. No readjustment is required after the replacement of the cables and pump main bodies.
  6. The self diagnostic functions ensure easy location of faulty part(s).
  7. The cable is available in any length between 3 meters and 30 meters.
