PST-140-04-DP
The Copley Controls PST-140-04-DP power supply, part of the PST Power Supplies series, delivers a stable +140VDC output at a continuous 3.5A load. Manufactured by Copley Controls, this unit offers an output power of 490 Watts and features a robust 15A thermal time-delay circuit breaker. Designed for industrial applications, its primary function is to provide dependable DC voltage for motion control systems, automation equipment, and other precision-driven processes.
Incorporating an input voltage range of 115/230VAC, 50/60Hz, the PST-140-04-DP supports global power standards and adapts to varying supply conditions. It boasts a high 6,800µF capacitance to filter and stabilize the DC output, while a 6.8kΩ resistance element manages current flow and thermal distribution. Under no-load conditions, the unit maintains a 159VDC potential to ensure immediate system responsiveness. Unique to this design is its internal thermal time-delay breaker, which withstands inrush currents and prevents nuisance trips during startup or transient faults.
Engineered for reliability, the PST-140-04-DP operates over a temperature span of 0°C to 50°C, with a derating curve of 0.86%/°C from 50°C to 65°C to preserve performance in warmer environments. Its maximum continuous current ratings of 7.6A (at low input voltage) and 3.8A (at high input voltage) must be considered during system integration. This power supply excels in industrial automation by delivering consistent output, minimizing downtime, and safeguarding connected devices against overload and short-circuit events.
