1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the EVERSECU 18 Channel DC12V 10 Amp Reset Fuse CCTV DC Distributed Power Box. This device is designed to provide stable and protected DC 12V power to multiple CCTV cameras, DVRs, and other security system components.
It features individual PTC fuses for each output, ensuring that a fault in one channel does not affect the operation of others. The robust metal housing provides durability and security.
2. Safety Information
- Electrical Safety: Ensure the power supply is disconnected from the main power source before performing any installation, maintenance, or troubleshooting. Only qualified personnel should perform electrical connections.
- Ventilation: Do not block ventilation openings. Ensure adequate airflow around the unit to prevent overheating.
- Environment: Install the unit in a dry, well-ventilated area, away from direct sunlight, heat sources, and excessive dust or moisture.
- Grounding: Proper grounding is essential for safe operation and to prevent electrical shock.
- Load Capacity: Do not exceed the total output current capacity of 10 Amps. Each channel has a maximum capacity of 1.1 Amps.
3. Product Overview
The EVERSECU power box is designed for efficient and reliable power distribution in CCTV systems. Key components include:
- Metal Enclosure: Durable and secure housing with a lock.
- AC Input: Standard AC power input (100-240V).
- DC 12V Outputs: 18 individual DC 12V outputs for connecting cameras or other devices.
- PTC Fuses: Resettable PTC fuses for each output, providing overcurrent and short-circuit protection.
- LED Indicators: Individual LED indicators for each output to show power status.
- Surge Protection: Built-in high voltage surge protection.

4. Setup and Installation
- Mounting: Choose a suitable, secure location for mounting the power box. Ensure it is within reach of a power outlet and the devices it will power. Use appropriate screws and anchors to securely fasten the unit to a wall or other stable surface.
- AC Power Connection: Connect the provided AC power cord to the power box's AC input socket and then to a grounded electrical outlet. Do not connect devices to the DC outputs yet.
- DC Output Connections: Open the power box. For each CCTV camera or device, connect its DC power input wires to the corresponding terminal block on the power box. Ensure correct polarity (positive to positive, negative to negative). Each output channel is clearly labeled.
- Secure Wiring: Double-check all connections to ensure they are tight and secure. Loose connections can cause intermittent power supply or damage to devices.
- Close and Lock: Once all connections are made and verified, close the power box cover and secure it with the provided lock and keys.
- Power On: Plug the AC power cord into the wall outlet. The LED indicators for each active channel should illuminate, indicating proper power distribution.
5. Operating Instructions
The EVERSECU power box operates automatically once connected to AC power and with devices attached to its DC outputs.
- Power Indicator LEDs: Each output channel has an associated LED indicator. A lit LED signifies that the channel is receiving power and the PTC fuse is operational. If an LED is off, it indicates a power issue on that specific channel (e.g., short circuit, overcurrent, or disconnected device).
- PTC Fuse Reset: In case of a short circuit or overcurrent on a channel, the PTC fuse for that channel will trip, cutting power to protect the connected device. Once the fault condition is removed, the PTC fuse will automatically reset after a short period, and power will be restored to the channel.
- System Monitoring: Regularly check the LED indicators to ensure all connected devices are receiving power.
6. Maintenance
Minimal maintenance is required for the EVERSECU power box. Adhere to the following guidelines:
- Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or aerosols. Ensure ventilation openings are free from dust and debris.
- Connection Check: Annually, or as needed, inspect all wiring connections inside the box to ensure they remain tight and free from corrosion. Always disconnect AC power before opening the unit.
- Environmental Check: Ensure the installation environment remains suitable (dry, well-ventilated, stable temperature).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to any device / No LEDs lit | No AC input power; Main power supply fault. | Check AC power cord connection and wall outlet. Verify the main power supply unit inside the box is functioning. |
| One channel has no power / LED off | Short circuit or overcurrent on that channel; Loose connection; Faulty device. | Disconnect the device from the affected channel. Check for short circuits in the wiring. Reconnect the device. If the LED remains off, the device may be faulty or drawing too much current. The PTC fuse will reset automatically once the fault is cleared. |
| Devices flickering or unstable power | Total current draw exceeds 10A; Loose connections; Voltage drop over long cables. | Reduce the number of connected devices or use a higher amperage power supply. Check all wiring connections. Use thicker gauge cables for longer runs to minimize voltage drop. |
| Unit is hot to the touch | Insufficient ventilation; Overload. | Ensure adequate airflow around the unit. Check if the total current draw exceeds 10A. Relocate if necessary to a cooler, better-ventilated area. |
