Current-Fed Topology: Robust Power Conversion

All MagnaDC programmable DC power supplies utilize high-frequency IGBT-based power processing in current-fed topology. This topology adds an additional stage over the conventional voltage-fed topology for enhanced control and system protection, ensuring that even under a fault condition, the power supply will self-protect. Due to the self-protecting characteristics of this topology, the possibility of fast rising current spikes and magnetic core saturation is eliminated.

In addition to its robust topology, key performance characteristics of MagnaDC programmable DC power supplies include:

  • High-accuracy voltage and current programming accuracy
  • Class-leading line and load regulation performance
  • High 3Φ AC input power factor with in-rush limiting circuitry
  • Computer and user I/O isolated from the power supply output

Designed and Manufactured in the USA, Available Worldwide

For complete control of quality, MagnaDC programmable DC power supplies are designed and manufactured at Magna-Power's vertically integrated USA manufacturing facility in Flemington, New Jersey. Heat-sinks and chassis are machined from aluminum. All sheet metal is fabricated and powder coated in-house. Magnetics are wound-to-order from validated designs based on a model's voltage and current. An automated surface-mount production line places components on printed circuit boards for control, driver, auxiliary power, and display circuits. And finally after assembly, products undergo comprehensive test and calibration, followed by an extended burn-in period.

Standard Safety Features

MagnaDC programmable DC power supplies have extensive diagnostic functions, including:

  • AC Phase Loss
  • Excessive Thermal Conditions
  • Over Voltage Trip (Programmable)
  • Over Current Trip (Programmable)
  • Cleared Fuse
  • Excessive Program Line Voltage
  • Interlock Fault

When in standby or diagnostic fault, the AC mains are mechanically disconnected by an embedded AC contactor, providing confidence that the unit is only processing power when desired.

Finally, with a dedicated +5V interlock input pin and included +5V reference on all models, external emergency stop systems can be easily integrated using an external contact.

Included Software and Drivers

All MagnaDC programmable DC power supplies come standard with National Instruments LabVIEW and IVI drivers. In addition, the support SCPI command set provides an easy to use API using ASCII commands over any interface.

In addition to being able to develop your own software, Magna-Power's Remote Interface Software is also included with all power supplies. The software provides the user with an easy and intuitive method to operate a Magna-Power Electronics power supply with computer control. The Remote Interface Software has six different windows, including:

  • Virtual Control Panel. Use a virtual front panel on the desktop to remote control the power supply from a computer.
  • Command Panel. Explore all the available commands, along with logs of what string the software is sending to the power supply; used for developing your own software.
  • Register Panel. Quickly get the status of all the power supply registers from one screen.
  • Calibration Panel. Recalibrate internal digital potentiometers.
  • Firmware Panel. Upgrade the power supply's firmware.
  • Modulation Panel. Emulate non-linear profiles, such as solar arrays, pseudo-resistance for N+1 redundancy without wires, or automatic compensation for leadless remote sensing.

The included Remote Interface software supports RS232, LXI TCP/IP Ethernet, and IEEE-488, along with the USB and RS485 converters.

High Performance Master-Slave Operation

All MagnaDC programmable DC power supplies come with master-slaving capability.

The MagnaDC master-slaving strategy helps to ensures no degradation in performance as units are added in parallel or series by providing gate drive signals directly from the master to the slave units. This strategy ensures one control loop for the system and eliminates the noise susceptibility commonly found when sending analog control references over long distances.

The Universal Interface Device 47 (UID47) accessory eases master-slave parallel or series configuration of Magna-Power DC power supplies, enabling near equal current or voltage sharing, depending on the configuration.

Master-slave series operation is supported to combined voltages up to the product's DC Output Isolation specification. No external blocking diodes are requires for series operation.

External User I/O for Analog Control

Using the rear isolated 37-pin I/O connector, included as standard, the MagnaDC programmable power supplies can be completely controlled and monitored using external signals. The voltage, current, over voltage and over current set points are set by applying a 0-10V analog signal. Each diagnostic condition is given a designated pin, which reads +5V when high. Reference +5V and +10V signals are provided, eliminating the need for external voltage signals and allowing the use of dry contacts.

Also, the power supply features a normally closed external interlock, which when enabled, allows the power supply to be tied in with other emergency stop equipment. All these pins are isolated from the output terminals and referenced to earth-ground as standard—no additional isolation equipment or options necessary.

The following list summarizes the available I/O from the power supply:

  • 4 analog inputs (0-10V)
  • 2 analog outputs (0-10V)
  • 5 digital inputs (5V)
  • 15 digital outputs (5V)
  • +2.5V, +5V and +10V reference signals

With the High Slew Rate Output (+HS) option equipped, high bandwidth operation is enabled along with fast rise times, allowing the MagnaDC programmable DC power supplies to address requirements for Hardware-in-the-Loop (HIL).
