Magna Power Electronics- Programmable DC Power Supplies (Model:SL SERIES: 1.5 KW TO 4 KW)

Innovative and Scalable

Magna-Power Electronics SL Series programmable DC power supply combine the best of DC power processing with microprocessor embedded control. A combination of high and medium frequency power processing technologies improves response, shrinks package size, and reduces cost. All Magna-Power Electronics DC power supplies arecurrent-fed and are more tolerant to abusive loads than conventional switching power supplies. This technology allows the power supply to operate under short-circuit conditions, open-circuit conditions and everything in between.

The programmable DC power supplies offer both master/slave parallel and series operation. This enables two or more power supplies to be placed in parallel for increased output current or in series for increased output voltage, within the unit’s isolation limits. With master/slave operation, power supplies operate at near equal voltage and current. The process of master/slaving power supplies is plug & play with the use of Magna-Power Electronics UID47 option, which can be added at any time. 

All supplies can operate as a voltage source or current source depending on the control settings and load conditions. If the power supply is operating as a voltage source and the load increases to a point beyond the current command setting, the power supply automatically crosses over to current mode control and operates as a current source at that setting.

Electronic Output Stage

The novel electronic output stage utilizes near constant power loading under all conditions via an electronic bleed resistance. This electronic bleeder means stability under all operating conditions and faster fall times, without affecting the overall system efficiency.

Attention to Power Quality

All SL Series power supplies contain circuitry to work harmoniously with other power equipment. Step-start contactors are used to keep inrush current below full scale operating current. Filter components lower current harmonic content emanating from the power supply and increase power factor to levels beyond 90%. Every power supply is tested at 90% to 125% nominal line to ensure satisfactory operation even under the worst line voltage conditions.

Model Ordering Guide

Models Chart

The following chart details the available standard SL Series models. The Current Maximum (Adc) column is separated by the available power levels. To determine the appropriate model, first select your output Voltage Maximum (Vdc) to find appropriate row. Next, select one desired Current Maximum from the row that contains your desired Voltage Maximum. Then, construct your model number according to the model ordering guide, above. Non-standard voltage and current configurations are available.
