UltraPoE PS-DC20A18UPC 18-Channel UL-Listed 12V CCTV Power Supply Box, 20A PTC
UltraPoE PS-DC20A18UPC is an 18-channel UL-listed centralized CCTV power supply box providing regulated 12V DC with a shared 20A total output capacity. Each channel uses a resettable 2.5A PTC fuse and an individual LED indicator so a fault can be isolated to one branch while the remaining outputs continue operating.
Key Features
- 18 protected outputs: Centralized 12V DC distribution for multi-camera security systems.
- 20A shared total capacity: Up to 240W nominal output across all connected loads.
- 2.5A resettable PTC per channel: Automatically restores the branch after an overload or short circuit is removed.
- Individual LED indicators: Supports quick channel-status checks during installation and service.
- Protection functions: Short-circuit, surge, thermal, and over-current protection.
- Locking ventilated enclosure: Organizes and protects field wiring while supporting airflow.
- Wide-range input: 100 to 240V AC, 50/60Hz.

Typical Applications
Suitable for compatible 12V DC CCTV cameras, analog HD cameras, PTZ cameras, IR illuminators, DVR accessories, access-control devices, and other low-voltage security equipment. For IP cameras, use only when the camera has a separate compatible 12V DC input.
Installation Notes
The 2.5A PTC rating applies to each protected branch. All 18 channels share the 20A total system capacity, so the combined operating and startup current must remain within that limit. Confirm voltage, polarity, current demand, cable size, and voltage drop before installation.
Frequently Asked Questions
Can all 18 outputs supply 2.5A simultaneously?
No. Each branch is protected at 2.5A, but the enclosure provides 20A total across all outputs. Add the current requirements of all connected devices when sizing the load.
What happens if one output shorts?
The affected channel's PTC fuse opens to protect that branch. It resets automatically after the fault is removed and operating conditions return to normal.
Does this power cameras through Ethernet cable?
No. This is a 12V DC distribution power supply, not a PoE switch or injector.
Is the cabinet lockable?
Yes. The ventilated metal enclosure includes a key lock to help control access to the wiring and power components.
