Description

The JPS300PV5.0A31 switching power is a high-performance switching power supply designed for stability and efficiency. With a total output power of 300W, this unit delivers a stable +5.0V DC output with a maximum current capacity of 60A. It is engineered to meet the rigorous demands of modern electronic systems, featuring a compact form factor, wide voltage input capabilities, and robust protection mechanisms.
1. Superior Efficiency and Power Factor
At the heart of the JPS300PV5.0A31 is a synchronous rectification circuit, which significantly enhances conversion efficiency and reduces energy consumption.
Efficiency: The unit achieves an efficiency of ≥88% at 220Vac input with a full load at room temperature.
Power Factor Correction (PFC): It incorporates a PFC circuit, ensuring a power factor of ≥0.95 under rated input voltage and full load conditions, making it an environmentally friendly choice that minimizes harmonic distortion.
2. Flexible Input and Output Performance
This power supply is designed for global compatibility and stable operation across varying conditions.
Wide Input Range: It supports a universal AC input range of 90–264Vac (50/60Hz), ensuring reliable performance in diverse geographical regions.
Output Stability: The output voltage is regulated to ±5% accuracy. Both line regulation and load regulation are maintained within ±2%, ensuring consistent power delivery.
Low Noise: The output ripple and noise are tightly controlled to ≤300mVp-p (measured at 20MHz bandwidth), providing clean power for sensitive electronics.
3. Comprehensive Protection and Reliability
Safety and longevity are paramount in the design of the JPS300PV5.0A31.
Protection Features: The unit includes Input Under-voltage Protection (60-80Vac), Output Current Limiting (66-90A), and Output Short Circuit Protection. Notably, it utilizes a “hiccup mode” self-recovery mechanism for short circuits, preventing damage during prolonged fault conditions.
Durability: The Mean Time Between Failures (MTBF) is rated at ≥50,000 hours.
Electrical Strength: It withstands high potential tests of 3000Vac (Input to Output) for 1 minute without breakdown, ensuring user safety.
4. Mechanical Design and Thermal Management
The power supply features a compact metal enclosure with a sandblasted and oxidized finish.
Dimensions: 165mm (L) × 56mm (W) × 26mm (H).
Cooling: It utilizes natural cooling (convection). However, for optimal thermal performance, the specifications require the installation of an external aluminum auxiliary heat sink (Recommended size: 315mm × 200mm × 3mm).
Environment: It operates reliably in temperatures ranging from -30°C to 60°C and can be stored between -40°C and 85°C.
