PS50A SERIES Description Power Ratings The PS50A non-isolated unregulated power Model AC Input DC Output Output Output supplies are designed to complement ADVANCED Number Supply Voltage Current Power Motion Controls’ high voltage servo drives. These PS50A 240 VAC 340 VDC 50 A 17 kW power supplies contain a rectifier bridge and filter 50 A 8.5 kW capacitors to generate the DC bus internally from PS50A-LV 120 VAC 170 VDC the AC input power. These DC power supplies are an excellent solution for multi-axis applications since ADVANCED Motion Controls’ servo drives compensate for power supply output variations and AC ripple components. � Surface-Mount Technology � Accepts Three Phase or Single Phase AC Supply � Built-In Shunt Regulator with Bicolor LED Indicator � External Shunt Resistor Provisions � Compact Design Compact Design PS50A Series Power Supply Operation Agency Approvals The DC bus voltage is 1.4 times AC voltage (RMS), US and Canadian safety compliance with e.g. 340 VDC from 240 VAC for the PS50A and UL 508c, the industrial standard for power 170 VDC from 120 VAC for the PS50A-LV. During conversion electronics. UL registered under braking much of the stored mechanical energy is file number E140173. Note that machine fed back into the power supply and charges the components compliant with UL are bus capacitor to a higher voltage. If this voltage considered UL registered as opposed to UL reaches the drive’s over-voltage shutdown point, listed, as would be the case for commercial output current and braking will cease. To ensure products. smooth braking of large inertial loads, a built-in shunt regulator is provided. Compliant with European CE for both the The shunt regulator will switch on the internal Class A EMC Directive 2004/108/EC on power resistor when the bus voltage reaches the Electromagnetic Compatibility (specifically shunt switch-on voltage. This allows the bus EN 61000-6-4:2007 and EN 61000-6- capacitor to discharge and thus lower the bus 2:2005) and LVD requirements of directive voltage. During regeneration, the regeneration 2006/95/EC (specifically EN 60204-1:2006), LED will blink (solid green is non-regeneration a low voltage directive to protect users from mode). An external shunt resistor can be added electrical shock. parallel to the internal resistor (between shunt terminals 1 and 2). Removing the jumper between shunt terminals 2 and 3 will disable the internal shunt resistor. RoHS (Reduction of Hazardous Substances) is intended to prevent hazardous substances such as lead from being manufactured in electrical and electronic equipment.
