Overview
1.1 General Description
The Intelligent High Power (iHP) series is an addition to Artesyn’s existing breadth of configurable AC to DC
power supply products. The iHP series offers the highest power and voltage rating in the configurable family
and provides the most flexible and universal solutions for medical and industrial applications. The iHP series
provides accuracy, resolution, and stability as either a programmable voltage or current source. The basic
modular concept consists of an iHP rack into which iHP modules are inserted. The rack is a Power Factor
corrected front-end converting worldwide standard AC input voltages into a regulated high voltage DC (HVDC)
output. The pluggable modules provide an extended range of voltage and current combinations converting
the HVDC input into programmable 3KW increments of output power. iHP output modules are configured into
a power system by plugging the modules into one of two different standard 19” AC-HVDC racks. One rack
houses up to four modules (12KW) and the other rack up to eight modules (24KW). Provisions are made for up
to six racks to be connected and controlled in parallel.
Safety approvals secured by Artesyn eliminate the need for an isolation transformer in medical equipment.
The iHP system also has industrial safety approvals, including compliance to the SEMI F47 standard for
semiconductor processing equipment.
The iHP series offers developers either an analog or digital interface to their system, supporting standard
communications protocols, including CANbus, Ethernet, and RS485. Digital control enables the use of
Artesyn’s high-level PowerPro software graphical user interface (GUI) to control and monitor all functions on
one or multiple iHP systems. The PowerPro GUI also incorporates graphical script creation that allows users to
write their own process control routines.
The iHP series offers efficient power factor correction (PFC) and low total harmonic distortion (THD) over a
wide range of loads. It uses a multi-phase continuous mode boost PFC architecture, resulting in ripple current
cancellation that offers lower EMI and extends the life of electrolytic capacitors.
Users can configure and customize the iHP modules to fit exact applications requirements. A qualified service
personnel can configure the iHP rack for single or three phase inputs. The modules can be connected in series
or parallel, while achieving accurate voltage and current sharing. Using grouping commands, modules in
parallel or series can be controlled as one single output. For specific types of load applications, the iHP system
can be programmed to three different compensation configurations including resistive load, capacitive load
and LED load. The LED load compensation opens new applications for large horticulture farms that require
high voltage for many LED strings tied in series.
1.2 Operational Overview
The iHP system is designed to be configurable to meet varied design requirements. The number of
configurable parameters is extensive and access to the parameters is via a computer interface instead of the
front panel. Before operating the supply, it is important that communication between a computer and the
supply be established and the supply operational parameters be configured for the intended application.
