Ups Fan Power Supply

"Product Introduction:

When the external power grid is interrupted during the operation of the elevator, the cross-flow fan stops running and the car lighting goes out. If passengers are trapped in the car, the space is closed, the air flow is poor, and the emergency lights are dim. It is easy to cause panic or even sudden illness while waiting for rescue. To solve this problem, some elevators will install UPS fan power supplies to supply power to the cross-flow fan and car lighting when the external power grid is out of power, so as to maintain the air flow and lighting inside the elevator car. (In Southeast Asian countries, such as Singapore and Malaysia, UPS fan power supplies are standard configurations for elevators);

Performance indicators:

1. Comply with the IEC 62040-1 UPS safety standard requirements and have been tested by a third-party organization;

2. Comply with the Housing Development Board of Singapore (Housing Development Board Board), referred to as "HDB", for UPS fan power supply requirements;

3. Redundant protection design, more stable and reliable performance. Output overload protection, output short circuit protection.

4. Intelligent charging management, using mature and stable constant current and voltage limiting charging, for maintenance-free lead-acid battery charging, the battery life is long and durable.

5. The self-discharge current of the equipment is nA level, reducing the low voltage damage of the battery due to self-discharge of the equipment before the equipment is put into normal use;

6. The equipment is not damaged by long-term input of high voltage

7. 485 communication port: can be connected to the computer to read fault information; input and output parameters can be Visualization.
