UltraPoE PS-DC20A18E 18-Channel 12V DC CCTV Power Supply Box, 20A PTC
UltraPoE PS-DC20A18E is an 18-channel centralized CCTV power supply box providing regulated 12V DC with a shared 20A total output capacity. Each channel has its own resettable 2A PTC fuse and LED indicator, helping isolate a fault to one output while the remaining channels continue operating.
Key Features
- 18 individually protected outputs: Centralized power distribution for multi-camera installations.
- 20A shared total capacity: Up to 240W at 12V DC across all connected loads.
- Resettable 2A PTC per channel: Automatically restores operation after an overload or short-circuit condition is removed.
- Individual LED indicators: Makes channel status easier to identify during installation and service.
- Multi-layer protection: Short-circuit, surge, and over-current protection.
- Locking metal enclosure: Helps secure connections and keeps power distribution organized.
- Wide-range input: Supports 100 to 240V AC at 50/60Hz.

Typical Applications
Designed for compatible 12V DC CCTV cameras, analog HD cameras, PTZ cameras, IR illuminators, DVR accessories, access-control equipment, and other low-voltage security devices. For IP cameras, use only when the device has a separate compatible 12V DC input.
Installation Notes
The 2A rating applies to each protected branch, while the combined current for all connected devices must remain within the 20A system total. Confirm device voltage, polarity, startup current, and cable voltage drop before installation.
Frequently Asked Questions
Can all 18 outputs deliver 2A at the same time?
No. Each branch has a 2A PTC limit, but all channels share the 20A total capacity. Size the connected loads so their combined current remains within 20A.
What happens if one camera cable shorts?
The affected channel's PTC fuse opens to protect that branch. Other channels can continue operating, and the PTC resets after the fault is removed and conditions return to normal.
Does this unit provide PoE?
No. It distributes 12V DC through dedicated power wiring and does not send power over Ethernet.
Is the enclosure lockable?
Yes. The metal cabinet includes a key lock for controlled access to the power and terminal connections.
