Robust Power Delivery for Automate Systems
The 45C93 power supply provides stable, regulated DC power for the Reliance Electric Automate control system. This power supply accepts a universal AC input of 85-264 VAC (47-63 Hz) or 120-370 VDC, accommodating diverse global power configurations. The unit delivers three isolated output rails: 5 VDC at 25 A, +12 VDC at 4 A, and -12 VDC at 2 A.
The 5 VDC output supplies the processor, memory, and I/O modules through the backplane. The ±12 VDC outputs power analog circuits, communication interfaces, and other specialized modules. The 45C93 maintains excellent regulation with line regulation at ±0.1% and load regulation at ±0.2%, ensuring stable module performance regardless of input variations.
Advanced Protection and Power Integrity
This power supply includes comprehensive protection features to safeguard both the unit and connected modules. Over-voltage protection (OVP), over-current protection (OCP), and short-circuit protection (SCP) activate automatically during fault conditions. The 45C93 shuts down safely and automatically recovers once the fault clears, preventing damage to system components.
The unit achieves a minimum hold-up time of 20 ms at full load, providing sufficient time for the controller to execute an orderly shutdown during power interruptions. The 85% efficiency rating minimizes heat generation and reduces energy costs. An internal fan provides forced-air cooling, maintaining optimal operating temperatures even in demanding environments.
Physical Design and Installation
This power supply mounts directly into the Automate 13-slot rack, occupying the dedicated power supply position. The unit measures 105 mm in width, 110 mm in height, and 160 mm in depth, weighing 1.2 kg. Three green LEDs on the front panel provide individual status indication for each output rail, enabling rapid troubleshooting during system startup.
The 45C93 requires no external wiring beyond the AC mains connection, drawing all necessary power from the backplane. The unit includes a standard IEC 320 C14 inlet for AC input, simplifying cable selection and installation.
Environmental and Operating Specifications
This power supply operates reliably across a temperature range of 0°C to +55°C. The 45C93 also withstands humidity from 10% to 90% (non-condensing) and resists vibration up to 2G at 10-100 Hz, making it suitable for demanding industrial environments. The unit’s universal input capability ensures compatibility with power systems worldwide.
