ZSN3 Series High-Power Switching Power Supply – Up to 18kW from a Trusted Chinese Manufacturer

Date：2026-07-16 02:42:19 Visit：5

ZSN3 Series Overview – Power That Scales

The ZSN3 series is a single-output chassis-type AC-DC/DC-DC power supply family engineered for high-power industrial applications-1. The series supports an input voltage range of 180–264VAC / 245–370VDC and a frequency range of 45–65Hz, making it compatible with power grids across global markets

Scaling Up to 18kW and Beyond

For applications requiring even higher power output, ZSN3 series units can be paralleled to achieve 18kW or greater total system power. This scalability makes the ZSN3 series an ideal solution for motor drives, robotic systems, industrial processing equipment, and automated production lines

Key Technical Features

High Precision and Stability

The ZSN3 series delivers exceptional output accuracy with:
  1. Voltage accuracy: ±1.0%
  2. Linear adjustment rate: ±1.0%
  3. Load regulation: ±1.0%
These specifications ensure stable power delivery even under fluctuating load conditions.

Fast Response Times

  1. Setup time: 1500ms
  2. Rise time: 100ms (at 230VAC, full load)
  3. The fast rise time enables rapid system startup, minimizing downtime in critical industrial processes.

Built-in Protection Mechanisms

The ZSN3 series incorporates multiple protection features for enhanced safety and reliability:
  • Short circuit protection: Enters constant current mode to safeguard both the power supply and connected equipment
  • Over-temperature protection: Automatically shuts down output when temperature exceeds safe limits; auto-resumes or restarts upon cooling
  • Built-in fan on/off control: Fan automatically adjusts speed based on operating temperature, balancing cooling efficiency with energy savings

Flexible Output Adjustment

The ZSN3 series supports wide-range output voltage and current adjustment via:
  • Onboard VADJ and AADJ potentiometers
  • External potentiometer control for remote voltage and current adjustment (customizable upon request)
  • Additional features include remote on/off control and auxiliary power output, offering maximum design flexibility for system integrators.

Applications

The ZSN3 series high-power switching power supply is widely deployed across numerous industrial and commercial sectors:
  • Industrial Automation: Large-scale machinery, automated production lines, robotics, and processing equipment
  • Scientific Research: Laboratory instruments, high-energy test equipment, and R&D systems
  • Telecommunications: Base station power systems and communication infrastructure
  • Renewable Energy: Solar inverter testing, energy storage systems, and power conversion
  • Medical Equipment: Imaging systems and therapeutic devices
  • Automotive Manufacturing: Motor testing and burn-in applications
  • Electroplating & Capacitor Aging: Specialized industrial processes requiring precise DC power
