Need help?Do you have a question about the multicomp pro MP710083 and is the answer not in the manual?
The Multicomp Pro MP710083 is a remote programmable power supply and DC waveform generator with Ethernet network connectivity, designed for laboratory and R&D applications. This multi-function constant power SMPS (Switched-Mode Power Supply) is capable of generating various DC waveforms, making it ideal for testing devices where irregular DC waveforms are important.
At its core, the MP710083 serves as a constant power laboratory-grade power supply. It features an automatic range of 0.5-36V and 0-5A, with a maximum output power of 80W. A micro-processor is utilized for generating the DC waveforms, offering 10 voltage generators that can be programmed either directly from the front panel or remotely via a PC.
The device supports remote programming for repetitive cycling, control, monitoring, and data logging through its USB port. With an optional Ethernet card, it extends its capabilities to Internet connectivity, allowing control, monitoring, and data logging for over 250 supplies from a single PC. Application software for cyclic programs, command sets, and Labview Drivers are provided to facilitate these advanced functions.
The MP710083 can operate in both Constant Voltage (CV) and Constant Current (CC) modes. In CV mode, the output voltage remains constant at the set value as long as the loading current is less than the set current. In CC mode, the output current remains constant at the set value, provided the load is sufficient to draw current equal to or greater than the set current.
A key feature is its ability to generate ramp up/ramp down waveforms, allowing users to set up to 10 steps for complex wave patterns. This includes triangular, saw-tooth, and rectangular waveforms, with settable voltage levels and run times for each step. The device can run a specified number of cycles or continuously.
The power supply also supports a Master/Slave configuration, enabling parallel connection of multiple units (up to 30) for increased power output. In this setup, the Master unit controls the voltage and current settings for all connected Slave units, and the load current is shared across all units. Each unit in a Master/Slave connection must have a unique address ID.
The front panel of the MP710083 provides a clear display and intuitive controls for operation. The upper 4-digit LED display shows voltage (V) and constant voltage (CV) status, while the lower 4-digit LED display can show either wattage (W) or amperage (A), along with constant current (CC) status. Indicators for Remote Control (RMT), Slave mode, Shift function, and Lock status are also present.
Two main knobs, "VOLT." and "CURR.", are used for adjusting output voltage and current, respectively. These knobs can be pressed to switch between coarse and fine adjustments, with the currently adjustable digit being highlighted.
Three preset program buttons (Pre. A, Pre. B, Pre. C) allow users to quickly recall frequently used voltage and current settings. These presets can be adjusted and saved, or reset to factory defaults.
The "AV/A" button controls the output ON/OFF status and also indicates when a ramp up/ramp down program is running (by flashing). The power-up output ON/OFF status can be configured to either default to OFF or resume the last status before power-off.
For enhanced safety and control, the device includes Upper Voltage Limit (UVL) and Upper Current Limit (UCL) features. Users can set maximum values for voltage and current adjustments to prevent accidental damage to the object under test. If the output voltage or current exceeds these limits, an alert will be displayed.
The front panel can be locked to prevent unintentional changes, either manually or automatically when the unit is under remote control. The "SHIFT MENU" button provides access to various settings and functions, including the ramp up/ramp down generator, watt-meter/amp-meter selection, and remote control interface selection.
The MP710083 is designed for indoor use and requires a grounded 3-pin AC source. Users are advised to keep the manual in a safe place for quick reference and pay attention to safety warnings and cautions.
The device incorporates several protection mechanisms, including Tracking Over Voltage Protection, Current Limiting Protection, Short Circuit Protection, Overload Protection, Over Temperature Protection, Upper Voltage Limit, and Upper Current Limit. These features help ensure the longevity of the power supply and the safety of connected equipment.
Cooling is achieved through natural convection, eliminating the need for internal fans and reducing noise.
For troubleshooting and maintenance, the manual provides guidance on replacing the AC fuse, emphasizing the importance of identifying and clearing the cause of the fuse blow before replacement, and using a fuse of the same type and rating.
A factory reset function is available to restore the preset programs, UVL, and UCL settings to their default values, which can be useful for troubleshooting or reconfiguring the device.
The remote control interface selection allows users to choose between USB and an optional Ethernet card for PC connectivity, ensuring flexibility in control and monitoring setups. The device comes with a CD containing the user manual, USB driver, and PC control software.
The product is marked with the CE symbol, indicating compliance with relevant European directives for electrical and electronic equipment. It also includes information regarding Waste Electrical & Electronics Equipment (WEEE) disposal, encouraging separate collection and recycling to minimize environmental impact.
