Section 1. About The XPR Power Supply
Overview
The XPR Series of programmable DC power supplies is designed for use in OEM,
ATE, burn-in, magnet charging, and other high power systems for a broad range of
applications. The XPR uses “Soft Switching” technology which provides superior
performance combined with a high level of user control through both front panel and
remote interfaces.
Features and
Options
• Zero voltage (soft) switching for low noise output, improved efficiency and
higher reliability
• Active Power Factor Correction (PFC) for lower input current draw and lower
current harmonic generation
• Remote voltage sense with 5V line drop compensation
• Automatic Voltage/Current mode crossover
• Remote interlock
• Simultaneous digital display of both voltage and current.
• Ten-turn front panel voltage and current controls for high resolution setting of
the output voltage and current from zero to the rated output.
• Front panel push-button control of output standby mode and preview of voltage,
current, or OVP setpoints. Front panel light emitting diode (LED) indicators for
voltage and current mode operation, OVP, remote programming mode, and
shutdown. Front panel control of OVP.
• Multiple units can be connected in parallel or in series to provide increased
current or voltage.
• Over Temperature shutdown, latching or auto reset.
• Remote analog voltage and current limit programming with selectable
programming ranges.
• External monitor signals for output voltage and current.
• Isolated analog remote programming control of the output voltage or current and
isolated readback of output voltage and current with the optional ISOL Interface.
• CSA Certified to UL 3111-1, CSA 1010.1; CE Mark; FCC Class A
