The MPR-2001, the ultimalte PV/hybrid telecommunications control system on the market. The MPR-2001 unique features include multiple PV,Load and alarm channels, the sophisticated EBBM™ control charge algorithm, 16 analog inputs, 16 digital inputs and 32 digital outputs, with our standard capacity to verify operations, manually operate the controls and adjust setpoints via PC computer via telephone modem.

The MPR-2001 PV controller is the ENHANCED version of the MPR-9400. The same microcomputer PCB is used with our new MPR-2001 I/O circuit board and software. This system provides multiple monitoring and control needs for advanced PV systems. This is especially required on larger PV powered sites by the Telecommunications industry.

All monitoring and programming is accomplished by either the use of the 3 X 3 keypad and 2 X 24 lighted LCD or by a PC computer directly, or via modem/telephone line. The MPR-2001 will control 6 sub-arrays, either 60A or 100A each, 3 load LVD and 3 CEMF load voltage conditioning channels. In addition, The MPR-2001 is the answer to the PV industry's needs for an enhanced mulifunction PV controller using our integrated microcomputer controls for larger power systems.

  VERSATILITY
  The MPR-2001 will control 12, 24, 48, 120, 240 & 480 VDC negative or positive ground systems with variable Amperes of PV array current as ordered. With its integrated design and 64 standard channels it will manage large PV-generator hybrid power systems.
  SOPHISTICATION
  Great care and time has been spent on the design of the hardware and software to create a truly robust, state of the art controller. The MPR-2001 is equiped with software that controls and monitors many parameters. Many of the digital alarms and analog input parameters are acted upon by the controllers algorithms. This list is to extensive to provide in this brochure. Please contact DST for more information on the sophistication of this controller.

  All control and sensing elements are in the high side of the power circuits, this enables all common-ground conductors to be connected together as required by the National Electric Code. Ease of control of operations is made possible by the software, accessed with keypad and LCD or computer via RS232 or modem. All setpoints of all channels are changeable and password protected. Charging algorithms can be selected from standard series to EBBM™ or pulse width with variable/timed hysteresis. The MPR-2001 incorporates- float charge, manual or automatic equalization and temperature compensation which will increase your battery life! Easily customized for your unique application !

  The MPR-2001 datalogs, ounce a day, important paramenters for diagnostic evaluation of the system.

  RELIABLE
  As in all of DST's products, the MPR-2001 series controller is manufactured to industrial and military standards. Through extensive Beta, laboratory testing, with many units commisioned, the MPR-2001 has proven its reliability and accuracy in unattended remote applications with ambient temperatures ranging from -40°C to 60°C. The power switching devices used are very reliable sealed Mercury Displacement Relays to provide millions of switching cycles. Multiple levels of protection have been applied to eliminate damage caused by reverse polarity and/or wrong voltage settings, lightning, surges, static, RF and EMF interference. All set points are stored in non-volatile memory and the Software includes self correcting routines and is fault tolerant. Digital circuits are supplemented by an Analog back up of HVD's and LVD's. All components meet UL specifications and PC boards are conformal coated. TWO YEAR LIMITED WARRANTY PERIOD
  GENERAL FEATURES
  Temperature Compensated PV Array Control
  PV regulation is accomplished by monitoring the temperature and voltage of the battery. With up to 6 sub arrays, the controller provides staged switching of these arrays using mercury displacement relays. The EBBM™ charge algorithm ensures that the PV energy captured will provide and maintain optimum battery charge condition and prolong battery cycle life.
  Load Management
  The battery voltage and State of Charge is continuously monitored. As the battery discharges, the MPR-2001 will perform staged disconnection the 3 loads to protect the battery from permanent damage. All Load LVD are progammable by the customer. The Loads can also be temperature compensated by factory or customer programming of the controller. LVD #3 can be programmed as a function of time of day ON/OFF.
  Alarms
  Alarms are available for monitoring and diagnostic purposes. Alarms are viewed via LED's, LCD indicators and relay contact outputs. These alarms can be monitored remotely or programmed to "Call Out" to a host computer and report an alarm using the MPRCOMM software package which will operate under DOS or Windows environments.
  Operator Interface
  Operator interface is locally accomplished by PC computer via RS232 port and MPRCOMM software. This interface method allow the user to evaluate performance, view all conditions and parameter and change setpoints and down load datalogging.
