Battery Powered Ion Pump Controller V3

Product code: LSA3.1

The LSA3 is a rechargeable battery powered controller for ion pumps with built-in pressure conversion. It displays the vacuum level in mbar for SAES™ NexTorr pumps of the types D100-5, D200-5, D300-5 and D500-5. An acoustic alarm indicates low low battery. An additional input for a Pt 100 sensor is provided allowing for temperature measurement of the LN2 cooled sample stage of a Cryo-UHV-suitcase or for monitoring bakout temperature. Continous battery driven operation is possible for a period of approximately 45h.

The standard LSA3 controller is configured to operate diode ion pumps (positive output polarity).
