Product Features & Applications

The SDY series dual power supply box is suitable for terminal dual-loop power supply systems with AC 50Hz, rated voltage 220V/380V, and rated current 60A-400A. It can realize automatic switching between main and standby power sources to ensure power supply reliability. Widely used in high-rise buildings, shopping malls, fire fans, elevators, emergency lighting and other scenarios. We offer on-demand customization and drawings-based customization services, and also provide customized solutions for supporting lighting distribution boxes to meet various power distribution needs.

1. Product Overview

The SDY dual power supply box is specially designed for terminal dual-loop power supply systems. It can automatically switch to the standby power supply when the main power supply fails, and switch back automatically after the main power supply is restored, ensuring power supply continuity. The equipment is suitable for scenarios with high requirements for power supply reliability such as high-rise buildings, commercial places, and industrial facilities, providing power supply guarantee for key loads such as fire fans, elevators, domestic water pumps, emergency lighting, and evacuation signs. The supporting lighting distribution boxes provide safe power distribution and protection for lighting circuits, adapting to civil and industrial lighting systems.

2. Core Features

  1. Dual Power Switching Function: Supports two working modes: fully automatic and manual + automatic. In fully automatic mode, the standby power supply is automatically put into use when the main power supply fails, and switches back automatically after power is restored; manual mode allows manual intervention switching to meet the needs of special working conditions.
  2. High Reliability Design: Equipped with complete electrical interlock protection to prevent parallel operation of two power sources and avoid power supply accidents; adapts to a wide current range of 60A-400A, covering most terminal power distribution scenarios.
  3. Strong Scenario Adaptability: The dual power supply box is suitable for power supply of key loads such as fire protection and emergency lighting. The lighting distribution box can flexibly configure the number of circuits to meet the power distribution needs of different lighting systems.
  4. Customization Service: Supports customized box size, circuit configuration, and protection level according to needs, and can also carry out exclusive design according to customer drawings to adapt to the installation and power distribution requirements of the project site.

3. Application Scenarios

  • High-rise buildings/office buildings: Uninterrupted power supply guarantee for elevators, fire pumps, and emergency lighting
  • Commercial complexes: Reliable power distribution for mall lighting, air conditioning systems, and security equipment
  • Industrial sites: Emergency power supply for production equipment, fans, and water pumps
  • Public facilities: Emergency lighting and power supply for key loads in hospitals, stations, and schools
