Online outdoor UPS is a company specializes in providing users with pure uninterrupted AC power equipment for outdoor communication and network equipment. It is mainly used for outdoor communication and network equipment, which are usually used in urban corners, remote suburbs, mountainous areas, etc. Designed for the power supply environment, adopting a series of designs such as high temperature resistance, severe cold resistance, salt fog resistance, corrosion resistance, dust resistance, waterproofing, lightning protection, etc., with a wide input voltage range, a wide input frequency range, and a pure, stable, and reliable output waveform. Advantages, it completely solves the interference of the harsh power supply environment on network communication equipment, power supply interruption and other phenomena, and is widely used in outdoor communication base stations in the fields of communication, radio and television, and aviation.

​

★Technical characteristics of online outdoor UPS

The outdoor integrated cabinet adopts the IP55 protection level, has the functions of dustproof and waterproof, and can meet the harsh outdoor environment.

Anti-high and low temperature design, the cabinet adopts design measures such as shading, heat insulation, temperature compensation, and strive to maintain the temperature in the cabinet to ensure the normal operation of the host and battery, and can adapt to normal operation under the environment of -20℃～+45℃.

With lightning protection and other surge protection, the system is equipped with a 1.2KV/10KA pluggable lightning protection device to effectively prevent lightning damage to the equipment.

2) Strong grid adaptability

Ultra-wide input voltage range and frequency range, the maximum input range of the mains can reach 110Vac～300Vac, and the frequency can reach 40Hz-60Hz, which is fully adapted to the harsh grid environment.

The input is equipped with a high-voltage protection circuit, which can withstand high voltage beyond the input voltage range for a long time without damage.

The online double conversion structure can completely eliminate the interference of the power grid spikes, noise, harmonics and other communication equipment.

Adopt advanced digital microprocessor control, simplify the control circuit, and improve the stability and reliability of the system.

Using power factor correction technology (PFC), high input power factor, reducing UPS's harmonic pollution to other equipment, improving the utilization rate of the power grid, and reducing UPS operating costs. It is a cost-effective green and environmentally friendly power supply.

Digital control technology makes the efficiency of the whole machine greater than 90%, reduces the loss of UPS itself, and reduces the temperature inside the cabinet.

Double conversion structure working mode, to ensure zero switching between mains and battery power supply, and to ensure that the load is uninterrupted.

It can realize the unattended function. After the battery discharge protection, when the utility power is restored and normal, the UPS will automatically start to supply power to the load.

The system is equipped with a fault diagnosis function, which can quickly determine the cause of UPS failure and locate the fault location of the UPS through the combination of LED display, making UPS maintenance convenient and fast.

It has a cold start function. When there is no mains power, the battery pack can be used to start the UPS directly to meet the emergency needs of users.

The system is equipped with RS232 and dry contact communication interfaces to facilitate access to the transmission system monitoring, and realize unified monitoring and management with other equipment.

A variety of optional installation accessories are provided to meet various installation requirements such as pole holding, wall hanging, and floor.

But it must be considered according to the actual situation of the customer. The usual installation method is floor-mounted installation. The bearing capacity of the pole and the wall must be considered.

Provide the optional function of secondary power-off (optional), when the battery is powered, the secondary load can be disconnected on time as needed to ensure the backup power supply time of the primary load, and a secondary power-off dry contact can be provided Signal.

SNMP can be installed to realize remote network monitoring and management, and provide real-time UPS data and information.

SNMP card enables multiple computers to monitor one UPS or one computer in the control room to monitor all UPSs (because outdoor machines are distributed in relatively remote places, to check the working status of UPS in time for management.

You only need to install the dry contact card (optional) to use the UPS monitoring function of the dry contact card to monitor and manage the power supply.

Dry node alarms, using relay output form.

Each alarm function: UPS failure, mains failure, low battery

Parameter definition of UPS dry node alarm output

UPS fault alarm:

When UPS mains voltage is too high or too low; output voltage is too high or too low; overload; short circuit, inverter temperature is too high; battery low; battery overcharge; UPS internal hardware failure, etc., UPS will A fault alarm has occurred.

Mains power failure:

When the load is less than 70%, and the mains voltage is ≤115±5V or ≥300±5V, the mains power is abnormal;

When the load is ≥70%, the mains voltage is ≤165±5V or ≥300±5V, the mains power is abnormal;

When the mains input frequency is less than or equal to 46HZ or ≥54HZ, the mains power is faulty.

3. Low battery warning:

When the battery discharge voltage is less than or equal to 11VDC (single battery), the battery low voltage alarm.

4. Access control alarm:

When the door is opened, the access control alarms.

Remarks:

The alarm output mode is the relay output type. When a fault alarms, the corresponding alarm point is short-circuited with the common point, and when it is normal, the corresponding alarm point and the common point are open.
