The ALx Series utilizes conventional linear MOSFET-based dissipative elements, allowing the series to achieve a very wide voltage-current operating range within the model’s maximum power rating. Using the same heat management innovations developed for Magna-Power’s high density programmable DC power supplies, the ALx Series’ conservative cooling ensures long product life in environments up to 50 °C ambient operating temperature.
MagnaLOADs 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. High-power resistor modules are fabricated and rigorously tested. An automated surface-mount production line places components on printed circuit boards for control, auxiliary power, and display circuits. And finally after assembly, products undergo comprehensive test and calibration, followed by an extended burn-in period.
There are many possible configurations for the ALx Series product. Using the following ordering guide and models chart to define the best model for your application.
| Model | Maximum Power | Maximum Voltage | Maximum Current | Package Type |
|---|---|---|---|---|
| ALx1.25-200-300 | 1.25 kW | 200 Vdc | 300 Adc | Rack-mount |
| ALx1.25-500-125 | 1.25 kW | 500 Vdc | 125 Adc | Rack-mount |
| ALx1.25-1000-60 | 1.25 kW | 1000 Vdc | 60 Adc | Rack-mount |
| ALx2.5-200-600 | 2.5 kW | 200 Vdc | 600 Adc | Rack-mount |
| ALx2.5-500-250 | 2.5 kW | 500 Vdc | 250 Adc | Rack-mount |
| ALx2.5-1000-120 | 2.5 kW | 1000 Vdc | 120 Adc | Rack-mount |
The size of ALx Series MagnaLOADs vary according to the product's maximum power output rating, in accordance with the following table:
| Power | Package | Size (H x W x D) | Weight |
|---|---|---|---|
| 1.25 kW | Rack-mount (3U) | 5¼" x 19" x 24" (13.34 x 48.26 cm x 60.96) | 40 lbs (18.1 kg) |
| 2.5 kW | Rack-mount (3U) | 5¼" x 19" x 24" (13.34 x 48.26 cm x 60.96) | 65 lbs (29.5 kg) |
