3500/15 AC power module of half height

The 3500/15 AC and DC Power Supplies are half-height modules and must be installed in designated slots on the left side of the rack. The 3500 rack can contain one or two power supplies with any combinations of AC and DC. Either supply can power a full rack.

The 3500/15 AC and DC Power Supplies accepts a wide range of input voltages and converts them to voltages acceptable for use by other 3500 modules. The following power supplies are available with the 3500 Series Machinery Protection System:
l Universal AC Power
l High Voltage DC Power Supply
l Low Voltage DC Power Supply

3500/15AC conversion is the conversion of AC to DC, its power flow can be bidirectional, power flow from the power supply to the load is called “rectification”, power flow from the load back to the power supply is called “active inverter”. The input of AC/DC converter is 50/60Hz AC. Because it must be rectified and filtered, the filter capacitor with relatively large volume is essential. At the same time, due to the safety standards (such as UL, CCEE, etc.) and EMC instructions (such as IEC, FCC, CSA), EMC filtering and components conforming to safety standards must be added to the AC input side, thus limiting the miniaturization of the AC/DC power supply. In addition, due to the internal high-frequency, high-voltage and high-current switching action, it is more difficult to solve the EMC electromagnetic compatibility problem, which also puts forward high requirements for the design of internal high-density installation circuit. For the same reason, The high voltage and high current switch increase the working loss of the power supply and limit the modularization process of AC/DC converter. Therefore, it is necessary to adopt the optimization design method of the power supply system to make its working efficiency reach a certain degree of satisfaction.
