NewPWR NPS-1600 Series AC-DC switching power supplies

NPS-1600 Series: 1600W

NPS-1600-12 (12V/133.4A), NPS-1600-24 (24V/66.7A), NPS-1600-48 (48V/33.4A)

The NPS-1600 Series is a high-power, high-density power supply designed for demanding applications that require robust and reliable performance. It sits in the upper mid-range of the NPS family, offering a balance of substantial power output, advanced features, and a compact form factor.

Key Features & Specifications

High Output Power: This series is rated for a continuous output power of 1600 Watts, making it suitable for powering multiple systems or high-current devices.

High Power Density: Engineered to deliver high power in a relatively compact chassis, often designed to fit standard 1U or 2U rack heights, optimizing space efficiency in equipment racks.

Wide AC Input Range: Features a universal input of 85 ~ 264 VAC (typically with a DC input range of 120 ~ 370 VDC), ensuring stable operation across global mains voltages and tolerating fluctuations.

High Efficiency: Achieves typical efficiency ratings of ≥ 90% (often up to 91-92%). This high efficiency reduces energy loss, operational costs, and heat generation, which is crucial for reliability.

Active Power Factor Correction (PFC): Includes built-in PFC circuitry (Power Factor > 0.95/0.99), minimizing harmonic distortion and ensuring compliance with international standards like EN61000-3-2.

Comprehensive Protection: A full suite of protection mechanisms safeguards both the power supply and the connected load:

Over Voltage Protection (OVP)

Over Current / Over Load Protection (OCP/OLP)

Over Temperature Protection (OTP)

Short Circuit Protection (SCP)

Cooling: Utilizes a temperature-controlled fan for cooling. The fan speed adjusts automatically based on internal temperature and load, providing optimal cooling while managing noise levels.

Safety & EMC Certifications: Complies with major international safety standards (e.g., UL 62368-1, cUL, TÜV, CE, CB) and meets EMC requirements for emissions and immunity, making it suitable for industrial and commercial environments worldwide.

Common Models and Output Configurations

The NPS-1600 series is commonly available in standard single-output voltages. The model number follows the pattern NPS-1600-XX, where XX denotes the output voltage.
