DHP SERIES
2 kW to 30 kW DC Programmable Power Supply

DHP SERIES 2 TO 30 KW DC Programmable Power Supply The DHP series DC power supplies provide a wide range of power levels delivered from a thin rackmount profile. Individual models provide DC outputs from 2 kW to 30 kW. The DHP’s modular design allows for easy system upgrades or field repair.* All models incorporate self-diagnostics that continuously monitor critical parameters to assure maximum system uptime. For ease of use, the DHP has a front panel keypad control and standard analog remote programming as well as an optional remote digital IEEE-488.2, RS 232 and Isolated Analog Input. Extensive programming capability allows storing individual auto sequences, voltage and current settings. During power up the output of the supply is disabled for optimum safety. Also, a LAST SET button returns the supply to its last voltage and current setting prior to being powered down. Each model is backed by a five year warranty. All models from 5-400V are TÜV tested, CE marked, UL and CUL approved. FEATURES Modular Design: The series has a unique modular design that results in three rackmount profiles: 2U for 2 kW to 3 kW, 3U for 5 kW to 15 kW and 6U for 16 kW to 30 kW. Extensive Controls: These supplies are programmable from a front panel keypad or remotely through operator selectable 5V or 10V analog inputs. Options include GPIB IEEE-488.2, RS 232 and Isolated Analog Input. Digital Displays: These digitally controlled supplies display a wide range of operational and diagnostic parameters. These parameters include: Power supply rating Output power, voltage and current All power, voltage and current set points and limits Present and highest AC input voltage Present and highest air inlet temperature Power and auto-step sequence settings Calibration setup Remote operation setup Diagnostics fault status summary •Power-Off Memory: Enabling the input power and pushing the LAST SET button will restore the supply to its last voltage and current settings during the last power-off cycle. •Power Monitors: Operating output ?power can also be displayed in addition to voltage and current. •Programmable Output: Nine commonly used power supply setups can be stored. In addition, nine programmed sequences up to nine steps long can be stored. •Internal Diagnostics: Internal operational parameters are displayed on command or when a fault occurs. These events are: Watch-Dog Timer: monitors the system’s microprocessors Controller: checks control board integrity Air Inlet Temperature: monitors and records highest input ambient air temperature AC high line: monitors and records highest AC input voltage Power Module Status: monitors integrity of each internal power module •Safe Power Up: In the local mode the output is disabled for additional safety at power up. •Ease of Paralleling: Setting up a parallel operation only requires adjusting voltage and current level at the master supply. •Soft Calibration: Calibration does not require removing chassis covers. •Operating Modes: Constant current, constant voltage and constant power (limit) modes are standard with each supply. Front panel LED’s indicates which mode is active. •External Shut Down: An external shutdown signal can be used to inhibit the output voltage. •Front Panel Lockout: When operated remotely, front panel controls are disabled. •Protection: The supplies have Overvoltage, Overtemperature, Overcurrent, Surge Limit, Soft Start, Brown Out and Short Circuit protection. Overvoltage set points can be activated from the front panel without applying power to the load. •Agency Approvals: UL and CUL to UL 1950; TÜV to IEC 950, CE Mark* •5 Year Warranty •CE Mark* *Does not include the 600V models Specifications - INPUT Voltage and Frequency: 2-3 kW: 190-253 VAC, 47-63 Hz, single-phase, 2-wire plus ground, 5-15 kW and 16-30 kW: 190-253 VAC, 47-63 Hz, three-phase, 3-wire plus ground, Delta or Wye may be used.
