Configurable PSU system has medical, industrial safety approvals
Safety approvals eliminate the need for an isolation transformer in medical equipment. The iHP power system also has industrial safety approvals and meets the SEMI F47 voltage sag tolerance standard for semiconductor processing equipment.
The iHP power system offers either an analogue or digital interface, supporting standard communications protocols, including CANbus, Ethernet and RS485. Digital control enables the use of Artesyn’s 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 system 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. The user can configure the iHP system for single- or three-phase input.
Users can configure the outputs as voltage or current sources and customize them to their exact applications requirements from a range of standard modules. These modules can be connected in series or parallel, achieving accurate voltage and current sharing. For specific types of loads and applications, the iHP series can be programmed to three different compensation configurations including resistive load, capacitive load and LED load. The LED load compensation opens up new applications for large horticulture farms that require high voltage for series LED strings.
