MAGNADC 麦格纳 SL系列 可编程直流电源 5 Vdc to 1500 Vdc output voltage/1.5 Adc to 250 Adc output current
Defining A New Class of 1U Power Supplies
The SL Series builds on over 40 years of power supply innovation at Magna-Power, designed from the ground up to meet the highly reliable power dense demands of ATE system integrators through Magna-Power's signature current-fed power processing topology. Utilizing state-of-the-art semiconductors and innovative internally designed and manufactured heat sinks, the SL Series offers industry-leading 1U (1.75” height) programmable power levels with models at 1.5 kW, 2.6 kW, 4 kW, 6 kW, 8 kW, and 10 kW, while still maintaining an ambient operating temperature rating up to 50°C.
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.
Made 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 various metal assemblies are machined from aluminum. 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 ensure high-quality board assemblies. 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.
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.
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 and PLC Control
Using the standard rear isolated 37-pin user I/O connector, the MagnaDC programmable power supplies can be completely controlled and monitored using external signals. The voltage, current, over voltage and over current set points can be set by applying a 0-10V analog signal. Remote start, stop, clear and interlock (emergency stop tie-in) are controlled by applying a 5V digital 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 communications and user I/IO pins are isolated from the output terminals and referenced to earth-ground as standard.

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.
