Hengtong Intelligent Dual Backup Power Supply is a power guarantee equipment designed specifically for high reliability scenarios. It adopts intelligent switching technology between primary and backup power supplies to ensure uninterrupted operation of critical equipment 24/7. The product is equipped with dual independent power supply modules, supporting multi-source input of mains power and UPS. When the main power supply is abnormal, it can seamlessly switch to the backup power supply within 0.1 seconds, completely eliminating the risk of power outage.

● Network management function of power supply: It can realize centralized network management software to display the working status of power supply, record alarm time and repair time, and query historical information.
● The automatic switching function of the power supply ensures uninterrupted power supply for front-end equipment. The built-in main and backup modules of the power supply automatically switch in less than 0.1 seconds in case of a fault, ensuring safe, stable, and reliable power supply for the equipment.
● Power standard rack mounted design: Adopting a standard 2U rack mounted design, it can be installed in a standard cabinet.
● Lightning protection grounding of power supply: The equipment fully considers lightning protection grounding measures, greatly improving the reliability of the power supply.
● Each power supply has advanced self recovery current limiting protection (cutting off output/automatic recovery) for each channel, and each channel has an independent LED power indicator light. When a front-end device (camera, power cord, etc.) connected to a certain channel short circuits, the channel self-protection does not affect the normal power supply of other channels. After troubleshooting, the channel automatically resumes power supply.
● Ventilation and heat dissipation of power supply chassis: The equipment has a good ventilation and heat dissipation system, which is conducive to long-term stable operation.
● Switching between primary and backup power sources.
● 32 output channels, each with an output current of up to 5A, and a total current of up to 30A.
● Support remote control output, each channel can be individually controlled remotely, all controlled (on/off).
● Local instrument displays for current and voltage.
● Overcurrent protection, protection is provided when the current exceeds 30A, and the overcurrent abnormal current instrument flashes slowly as a warning.
● Abnormal voltage, slow flashing warning on the instrument.
● User defined overcurrent protection plan setting, when exceeding 30A, the output channel will be closed according to the plan.
● 1-channel switch input, used as a mains power outage detection, can be configured in advance to turn off which outputs, saving UPS energy and ensuring longer operation time of important equipment.
● Continuous setting of mains power outage, when detecting mains power outage, gradually shut down the equipment according to the time progression to ensure longer battery life of important equipment (if a power outage is detected, immediately turn off the exhaust and dust removal equipment, turn off the intercom equipment one hour later, turn off the monitoring equipment two hours later... until only the alarm equipment is retained until all UPS power is consumed.
● Remote control the main power supply and restart the default main power supply.
● The center monitors current, voltage, and temperature in real-time.
● Two relay outputs are used as event linkage.
● Local LED displays current and voltage.
● Real time clock, which can be set to turn off or turn on which outputs at regular intervals.
● Supports DC 12V output, indicating operation when switching to backup power supply.
