UltraPoE 1U 12V 20A 18-Channel Power Supply
Features include universal AC input (100-240V) with green LEDs for easy status visibility. It provides a high-capacity DC 12V output across 18 fused ports (16x 3A, 2x 5A). Independent PTC fuses and lightning protection help isolate faults and keep other outputs running. Best for large deployments with many cameras or devices requiring distributed power.
- Best for: Professional CCTV systems needing many outputs.
- Why selected: High channel count and robust protection.
Caution: The fused ports require careful load planning to prevent overdraw on the 20A supply.
ENS 18 Channel Rack Mountable CCTV Power Supply Box
This 1.5U rack-mountable unit delivers 12V DC across 18 channels with a total 20A output. It includes PTC resettable fuses per channel for strong overcurrent protection and short-circuit safeguards. It suits organized, space-efficient installations in security rooms or equipment racks.
- Best for: Controlled, multi-camera deployments in professional settings.
- Why selected: Compact 1.5U footprint with distributed channels.
Caution: Ensure fit in your rack’s 1.5U space and verify cable management for 18 outputs.
The Wires Zone 1U Rack Mount DC 18 Channel Power Box
Features include a digital power supply with an LED indicator for each output and 18 total channels. The module is designed for security systems with multiple devices, offering straightforward monitoring and control. It’s a practical option for mid-sized setups that prioritize visibility of each output.
- Best for: Installations needing per-channel status indication.
- Why selected: Clear channel-level feedback via independent LEDs.
Caution: May require additional cable organization for 18 distinct outputs.
EVERSECU 17CH 20A DC12V Power Supply Box
Offering 17 outputs with PTC fuses and independent LED indicators, this unit includes lightning protection and a long operational life. It aims at security systems that require isolated protection per channel, reducing risk effects from a single fault. Best for mixed camera types and DVRs/NVRs in one rack.
- Best for: Systems needing robust per-output protection.
- Why selected: Independent fuses help keep others functional during a fault.
Caution: 17 outputs may still require careful distribution planning to balance loads.
EVERSECU 17CH 30A DC12V Rack Mount Supply
This 1.5U/19 rack-mount unit provides 17 outputs with PTC fuses and a 30A total capacity. It includes independent protections and LED indicators per output, plus surge protection. It’s suited for sites with higher power demands or more devices per channel, while maintaining channel independence.
- Best for: High-demand installations requiring more headroom per channel.
- Why selected: Higher current capacity supports power-hungry devices.
Caution: Higher current capacity can tempt heavier load distribution; ensure cable gauges match the power delivery needs.
EVERSECU 1.5U/19 Rack Mount 9 Channel DC12V 10A
This 1.5U unit provides 9 outputs with PTC fuses and per-output LED indicators. It is suitable for smaller or entry-level security installations that still need reliable, distributed 12V power for cameras, DVRs, and IP devices. Independent protection helps limit fault impact.
- Best for: Smaller systems or initial security setups.
- Why selected: 9-channel option with per-output protection and indicators.
Caution: Lower total current (10A) means careful load budgeting is essential.
Buying Guide
What to consider when choosing a rack-mount 12V power supply:
- Channel count and total power: Match the number of devices and anticipated load to the unit’s total amperage (A) and per-channel fuse ratings.
- Protection architecture: Look for independent per-output fuses, LED indicators, and surge/lightning protection to minimize cascading failures.
- Rack compatibility: Confirm the unit fits your rack space (1U, 1.5U, etc.) and that mounting rails and cables are manageable within the enclosure.
- Input power range: A universal input (100–240VAC) supports regional voltage differences and simplifies installation.
- Cable management: Assess the number of outputs and plan for cable routing to avoid clutter and overheating.
- Future expansion: If you anticipate adding more cameras or devices, choose a unit with higher headroom or modular expansion compatibility.
Frequently Asked Questions
What is the main difference between 18-channel and 9-channel power supplies?
The primary difference is the number of outputs and total current available. 18-channel units distribute power across more devices, while 9-channel units are suited for smaller systems.
Do these power supplies protect individual outputs?
Yes. Many models include independent PTC fuses and per-output indicators to protect each channel from faults without cutting power to others.
Can I mix 12V devices in one rack with these supplies?
Yes, but plan loads by device current and ensure the total does not exceed the supply’s capacity. Use per-output protections as a safeguard.
What should I consider for long-term reliability?
Look for durable metal enclosures, surge protection, and high-quality fuses. Confirm the unit has a long service life and adequate heat management for continuous operation.
Is universal AC input necessary?
Universal input is convenient for cross-regional installations and simplifies provisioning during deployments.
Do I need a DIN-rail power supply?
For some installations, a DIN-rail mountable unit (DIN-rail compatible) is preferred for easy integration with other industrial controls.
