PS50A SERIES Description Power Ratings The PS50A non-isolated unregulated power supplies are designed to complement ADVANCED Motion Controls’ high voltage servo drives. These power supplies contain a rectifier bridge and filter capacitors to generate the DC bus internally from 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. Model Number AC Input Supply DC Output Voltage Output Current Output Power PS50A 240 VAC 340 VDC 50 A 17 kW PS50A-LV 120 VAC 170 VDC 50 A 8.5 kW 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), e.g. 340 VDC from 240 VAC for the PS50A and 170 VDC from 120 VAC for the PS50A-LV. During braking much of the stored mechanical energy is fed back into the power supply and charges the bus capacitor to a higher voltage. If this voltage reaches the drive’s over-voltage shutdown point, output current and braking will cease. To ensure smooth braking of large inertial loads, a built-in shunt regulator is provided. The shunt regulator will switch on the internal power resistor when the bus voltage reaches the shunt switch-on voltage. This allows the bus capacitor to discharge and thus lower the bus voltage. During regeneration, the regeneration LED will blink (solid green is non-regeneration mode). An external shunt resistor can be added 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. US and Canadian safety compliance with UL 508c, the industrial standard for power conversion electronics. UL registered under file number E140173. Note that machine components compliant with UL are considered UL registered as opposed to UL listed, as would be the case for commercial products. Compliant with European CE for both the Class A EMC Directive 2004/108/EC on Electromagnetic Compatibility (specifically EN 61000-6-4:2007 and EN 61000-62:2005) and LVD requirements of directive 2006/95/EC (specifically EN 60204-1:2006), a low voltage directive to protect users from electrical shock. RoHS (Reduction of Hazardous Substances) is intended to prevent hazardous substances such as lead from being manufactured in electrical and electronic equipment.
