The integrated power cabinet is mainly used for wireless communication base stations, including the new generation of 5G systems, communication/network integrated services, access/transmission exchange stations, emergency communication/transmission, etc.

An outdoor power cabinet is an enclosure specifically designed to operate in external environments. It serves to protect power equipment, communication hardware, and other electronic components from environmental hazards. Key attributes include robust structural engineering, high protection ratings, environmental resilience, safety features, and more.

These cabinets are typically made from durable materials such as galvanized steel, stainless steel, or aluminum alloy, offering strong resistance to corrosion and oxidationmaking them ideal for prolonged outdoor use. With protection levels of IP55, IP65 or higher, they effectively guard against dust, water, and humidity. Cabinets with higher ratings can even withstand heavy rain or sandstorms.

In contrast, an indoor power cabinet is generally installed in climate-controlled rooms, where temperature and humidity are stable, and environmental exposure is minimal. These cabinets often come pre-equipped with monitoring displays that provide real-time information on power consumption and system status.

1. Cabinet Size Design

Input:

List of device dimensions (height, width, depth)

Output:

(1) Cabinet Footprint (Base Dimensions)

• Determined by the largest device depth

• Includes additional space for cable management and ventilation channels

(2) Cabinet Height

• Based on the total height of all installed devices, including power supply units and batteries

(3) Load Capacity Design

• Calculated from the total weight of all components installed inside the cabinet

(4) Cooling Strategy

• Depends on the cumulative heat output of all active devices

(5) Grounding System

• Defined by the number and type of electronic components requiring grounding

2. Power Capacity Design

Input:

List of devices with power ratings (Voltage and Current)

Output:

(1) Power supply unit

• Must support the full power demand of all installed devices

• Include a power margin of 20% to 30% for system stability

• Rectifier selection depends on input source (AC-to-DC or Solar-to-DC)

• N+1 redundancy recommended for high availability

(2) Miniature Circuit Breakers (MCB)

• Output MCBs sized according to device current ratings

• Input MCBs (AC) based on total power load and input voltage

• Battery MCBs dimensioned for the maximum charge/discharge current

• LLVD (Low-Voltage Load Disconnect) and BLVD (Battery Low Voltage Disconnect) supported if needed

(3) Battery quantity

• Defined by backup time requirements and total power draw in case of outage LLVD (Low-Voltage Load Disconnect) and BLVD (Battery Low Voltage Disconnect) supported if needed

1. Core Monitoring Functions

(1) Water Leak Detection

• Sensors placed at the base of the cabinet detect the presence of moisture or flooding.

• Triggers alerts to prevent short circuits or equipment damage due to water ingress.

(2) Door Status Monitoring

• Magnetic or mechanical sensors monitor whether the cabinet doors are open or closed.

• Can be integrated with security systems to detect unauthorized access attempts or vandalism.

(3) Smoke Detection

• Early-warning smoke sensors are installed inside the cabinet to detect fire hazards.

• Helps prevent equipment damage due to overheating or electrical faults.

(4) Temperature & Humidity Monitoring

• Sensors measure internal ambient temperature and relative humidity.

• Triggers alerts when thresholds are exceeded, enabling preemptive action before thermal shutdown or condensation occurs.

(5) Power System Alarms

• Monitoring of AC/DC voltage levels, current flow, rectifier/battery status, and backup power availability.

• Ensures stable and redundant power operation.

(6) Access Control Integration

• Optionally linked with card readers or biometric systems to log and control physical access.

2. Dynamic Environmental Monitoring System (DEMS)

An advanced Dynamic Environment Monitoring System can be integrated for intelligent management and remote supervision. It typically includes:

• Centralized Monitoring Unit (CMU) that collects and transmits sensor data

• Real-time alarms and event logging

• Remote access via web, SNMP, or mobile application

• Automated reports for maintenance and compliance

• Predictive analytics for proactive system health checks

Benefits:

• Reduces downtime and service interruptions

• Enhances asset protection and personnel safety

• Enables remote and automated supervision

• Supports compliance with telecom site regulations and SLAs

600x700x2000mm, 600x800x2000mm, 600x1200x2000mm, etc.

The indoor power cabinet is typically constructed using powder-coated galvanized steel, offering excellent corrosion resistance and long-term durability.

When integrated into a facility with an existing forced air cooling system, indoor cabinets can be deployed in high￾density configurations, contributing to efficient thermal management across the equipment room. For simpler setups, cabinets equipped with passive ventilation grilles or low-noise fans offer a cost-effective cooling solution while minimizing design complexity and potential failure points—particularly when the room is already well-ventilated.

To aid in maintenance and monitoring, indoor cabinets are often fitted with vented or transparent front and rear doors, allowing for visual inspection of internal equipment without compromising safety or protection.

A customized cable management system includes integrated cable channels, adjustable brackets, grounding strips, and modular routing options to simplify installation and minimize electromagnetic interference—a critical factor in sensitive indoor IT environments.

Mounting rails are fully compliant with the 19-inch rack standard, supporting a wide range of power, IT, and network equipment.

Fire-retardant construction materials and optional smoke detection systems further enhance compliance with indoor safety standards.

The cabinet's smooth, neutral-toned exterior is designed to aesthetically complement office or data center environments, avoiding the industrial appearance typical of outdoor enclosures.

Overall, indoor power cabinets emphasize flexibility, ease of integration, and compatibility with IT infrastructure, while ensuring reliable power distribution and operational safety.

4. Battery

When the mains is interrupted, the communication battery acts as the emergency power supply and takes over the power supply immediately to prevent communication interruption, ensure that mobile networks can still make calls and transmit data normally during power outages.

Lithium batteries and lead-acid batteries are wildly used in the telecommunication system.

MCB (Miniature Circuit Breaker) is a protection device in power systems that automatically cut off current in the event of a circuit failure (such as overload, short circuit, leakage, etc.) to prevent equipment damage, fire, or personal injury.

In the power cabinet solution, both input AC and output DC circuit are use MCB to protect the device in good condition.

SPD (Surge Protective Device) is a device used to protect electrical and electronic equipment from transient overvoltage (such as lightning strikes, operating overvoltage, etc.). Its core function is to ensure the safe and stable operation of the system by limiting the voltage amplitude and releasing the inrush current.

SPD is only for the input end, such as AC input and battery input protection, keep the power system safe avoid the lightning strikes.
