4.8 Electrical data
The nEXT pumps c
an be driven by either the customers system or by the Edwards TIC
Turbo Instrument Controller, TIC Turbo Controller or TAG Controller.
If using the customer system, an appropriate, pre-approved, UL/CSA rated 48 V d.c.
power supply should be used. The size of the power supply required depends on the
applicaon and the power limit congured in the nEXT pump. The power limit seng
determines how quickly the pump ramps up and dictates the size of the power supply
required. If serial communicaons is available, the power limit seng of the nEXT pump
can be selected.
Refer to Table: Logic interface technical data for the maximum power limit sengs for
nEXT pumps. If the applicaon requires rapid cycling of the pump, faster ramp mes can
