Current-Fed Topology: Robust Power Conversion
All MagnaDC programmable DC power supplies utilize high-frequency IGBT- and MOSFET-based power processing in a 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. This topology coupled with state-of-the-art Silicon Carbide (SiC) power semiconductors enables the MagnaDC power supplies to deliver class-leading power density, reliability, and efficiency with continuous full-power operation up to 50°C ambient.
Made in the USA, Available Worldwide
MagnaDC programmable DC power supplies are designed and manufactured at Magna-Power’s 73,500 sq-ft vertically integrated USA manufacturing facility in Flemington, New Jersey. From raw materials to the completed product, Magna-Power has insourced nearly the entire production process to maintain complete control of quality, cost, and build-time. Heat-sinks and various metal assemblies are machined through both automated CNC and EDM. Sheet metal is cut, punched, sanded, bent, and powder coated in-house. Magnetics are wound-to-order from validated designs based on a model’s voltage and current. A full surface mount technology (SMT) with multiple stages of 3D automated optical inspection ensures high-quality printed circuit board assemblies. Finally, after assembly, products undergo comprehensive test and calibration, followed by an extended burn-in period.
Products are sold directly from the factory and through distribution, with a service network around the world.
Standard Safety Features
MagnaDC programmable DC power supplies feature a soft-start circuit to eliminate large peak in-rush currents from the AC mains, ensuring AC current draw never exceeds the current draw at full load. In addition, extensive safety and diagnostic functions are included, as follows:
- AC Phase Loss
- Over Voltage Trip (Programmable)
- Over Current Trip (Programmable)
- Cleared Fuse
- Over Voltage on Program Line Input
- Over Temperature on Internal Heatsinks
- Safety Interlock / Emergency Stop 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. Users can easily identify faults using the Status message display or by SCPI commands.
Finally, the interlock / emergency stop input is included as standard. This feature provides a 5V interlock input, which when coupled with the provided 5V reference signal, allows for a dry contact to easily trigger a latching interlock fault, while maintaining control power.
Limitless Programming Capabilities
With support for Standard Commands for Programmable Instrumentation (SCPI), MagnaDC power supplies provide an easy to use API with ASCII commands in readable text. Over 40 commands allow programmatic access to product registers, starting and stopping the product, control of voltage and current, high-accuracy measurement queries, and product configuration. Simple scripting or complex software can be achieved, with extensive documentation and examples provided by Magna-Power.
MagnaDC power supplies include RS232 communication interface standard with optional LXI TCP/IP Ethernet (+LXI) and IEEE-488 GPIB (+GPIB) options.
External User I/O for PLC Control or PHIL Simulation
Using the rear User 37-pin I/O connector, the MagnaDC 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.
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 programming inputs
- 2 analog measurement outputs
- 5 digital inputs
- 15 digital outputs
- +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 MagnaDC power supplies to address requirements for Hardware-in-the-Loop (HIL).
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.
Magna-Power Software, NI LabVIEW Drivers, and IVI Drivers
All MagnaDC power supplies come standard with an IVI driver and an NI LabVIEW driver featuring a full set of VIs. Get started quickly with either driver using included example programs.
Magna-Power's included Remote Interface Software (pictured) provides an easy and intuitive method to operate a Magna-Power Electronics power supply with computer control. The software includes a virtual control panel, command panel to explore available commands, register panel to monitor the power supply status, calibration panel for recalibrating internal digital potentiometers, firmware panel for upgrading firmware, and a finally a modulation panel to emulate non-linear profiles.
All communication interfaces are supported across the various methods to program MagnaDC power supplies.
