2. INTRODUCTION
2.1. General
description
NEG POWER
is an electronic unit specifically designed to control the heating and the activation
process of the getter pumps whether they are or aren’t equipped with a thermocouple.
There are two versions: NEG POWER for up to 4 controlled pumps, NEG POWER SMALL
supporting up to 2 pumps only.
NEG POWER
can control up to 4 different getter pumps at the same time, with an adjustable DC
voltage output up to 110 V, current up to 10A, power up to 700W.
It has a touch screen display to control all the pumps together and in a very friendly way; it is also
possible to control the NEG POWER by the SAES remote control software.
NEG POWER SMALL
is the smaller version of NEG POWER that can control up to 2 different
getter pumps.
Both versions can be equipped with standard 700 W modules or with low power 150 W modules.
(see paragraph 2.4).
The most popular SAES NEG pumps are preset in the software (like the GP SORB AC
®
, the
CapaciTorr
®
, CapaciTorr HV
®
and NEXTorr
®
families), so that in order to activate the NEG pump
just the pump model must be selected and START button pressed.
Other pumps, not included in the list of presets, can be managed by “custom settings” by choosing
suitable operating parameters.
