microIOC-LOCO2 is a high-voltage power supply stand alone unit that can distribute power to up to 16 ion-pumps. Varian Dual Controller is used as a power supply and microIOC-LOCO as the distribution system. To enable direct integration into the control system microIOC is integrated into the unit.  The unit can be controlled also locally using an LCD located on the front panel.
In addition to providing power to the pumps, current going through every pump is measured and pressure at the pump is determined. If the measured pressure is outside the desired limits, interlocks can be triggered to avoid pump damage. Every pump can be disconnected separately.

microIOC-LOCO2 is an ideal solution to cut costs and rack space by at least a factor of 2 of vacuum systems where a large number of smaller pumps are used, such as storage rings and boosters.
It is a preferred solution over microIOC-LOCO when single pump disconnection is desired or when integration wants to be avoided.

allowable output current	2x 400mA
allowable output power	420W max
output high-voltage connector	Fischer D105A049 with interlock (other type on request)
high voltage output current measurement / channel

current measurement range	100pA – 10mA
normal range of operation	400mA
current measurement principle	measured and integrated over 1 and 10s interval (other intervals on request)
current accuracy	guaranteed: ± 10%, typically: ± 5%
high voltage output channel ON/OFF switching / channel
switching method	when needed that any of the switches should change a state (opened or closed) firstly request to HV power supply sends to switch OFF output voltage and then switches state changes would be done
switching time	max 5s for the whole switching procedure: waiting that output voltage falling under 50V, changes states on switches, rising output voltage to final value
