Battery Powered Ion Pump Controller V3

Product code: LSA3.1

The LSA3 is a rechargeable battery-powered controller designed specifically for ion pumps, equipped with a built-in pressure display. Calibrated to showcase vacuum levels in mbar for SAES™ NexTorr pumps (D100-5, D200-5, D300-5, and D500-5), it includes an acoustic alarm signalling low battery levels. It also features a Pt 100 sensor input, facilitating temperature measurements for LN2-cooled sample stages in Cryo-UHV-suitcases or for monitoring bakout temperature. Offering approximately ~45 hours of continuous battery-driven operation for the ion aspect of the pump, note that the NEG part of the pump operates without power.

The standard LSA3 controller is configured for diode ion pumps with positive output polarity.
