EPCOM POWERLINE
Long Distance Power Supply Adjustable Voltage 11-15 Vcc @ 5 Amper for 4 Cameras, Input Voltage: 110 ~ 240 Vac
$20.99
12 VDC @ 5.0A 60W Output Adjustable 11–15 VDC 4 Outputs 120mV Ripple 6.30" x 2.28" x 1.44"
Adjustable output voltage
A screwdriver-adjustable pot on the terminal end lets you raise the output to offset cable losses — no need to re-pull thicker wire or add a second supply closer to the camera.
| Adjustment range | 11 – 15 VDC |
| Output ripple | 120 mV |
| Typical setting | 12.5V for analog / TurboHD |
Protection & distribution
One shorted camera lead shouldn't take down the other three. Over-current and short-circuit protection plus a resettable PTC fuse keep the rest of the system online.
| Outputs | 4 screw terminals |
| Per-output capacity | Up to 3A |
| Fuse | 6A PTC, self-resetting |
Why adjustable voltage matters on long runs
Copper has resistance. The longer and thinner the cable, the more voltage disappears before it reaches the camera. A fixed 12V supply can leave a distant camera running at 10V or less — the classic cause of night-time reboots when the IR array kicks in.
01
The symptom
Camera works by day, reboots or drops out at night. Image flickers. IR looks weak. Everything tests fine at the bench.
02
The cause
Voltage drop across the run. When IR LEDs switch on, current spikes and the drop gets worse — pushing the camera below its minimum operating voltage.
03
The fix
Raise the supply output so the voltage measured at the camera lands back around 12V. Adjust, measure at the far end, confirm.
How to set it correctly
- Wire and power the camera at the end of the run.
- Measure DC voltage at the camera's power input, not at the supply.
- Trigger night mode so the IR array draws its full current, then measure again.
- Adjust the output pot until the camera reads within its rated input range under IR load.
- Never exceed the camera's maximum rated input voltage — check the camera datasheet before going above 12V.
Main Features
- Output: 12 VDC @ 5.0A, 60W total
- Adjustable output: 11 – 15 VDC
- 4 independent camera outputs
- Up to 3A per output
- Supports 12.5V for analog & TurboHD cameras
- Conversion efficiency above 85%
- Output ripple: 120 mV
- LED power indicator
Electrical
- Input: 96 – 264 VAC, 47 – 63 Hz
- Input current: 1.5A
- Load loss: 0.5W
- Over-current protection
- Short-circuit protection
- 6A PTC self-resetting thermal fuse
- Constant output voltage regulation
Physical & Environment
- Dimensions: 6.30" x 2.28" x 1.44"
- Input: U.S. plug (NEMA)
- Output: 4 screw-terminal connectors
- Wall-mount keyhole slot
- Operating temp: 14°F ~ 113°F
- Operating humidity: 20 – 90% RH, non-condensing
- Storage temp: -4°F ~ 185°F
You'll likely need connectors
This supply terminates in screw terminals, not barrel jacks. Most cameras expect a 3.5 mm (0.13 in) male plug — so plan on pigtail adapters for the jump from terminal block to camera.
Choosing the right 4-camera supply
All three power up to four cameras at 12 VDC. What differs is voltage adjustability, noise filtering, and battery backup.
| Model | Output | Adjustable voltage | Best for |
| PS-12-DC-4C | 12 VDC @ 5A | Yes, 11–15 VDC | Long cable runs, analog / TurboHD |
| PS-12DC4KV | 12 VDC @ 5A | No | 4K cameras — adds noise filter & surge protection |
| PLK12DC4ABK | 12 VDC @ 4A | No | Sites needing battery backup (battery sold separately) |

Before you power up
- Verify input and output wiring polarity before applying power — reversed polarity can damage the connected device.
- After energizing, confirm the output LED is lit. If it isn't, re-check the wiring before troubleshooting anything downstream.
- Budget your load: 5A total across four outputs, up to 3A on any single output. Add up your cameras' draw at full IR before committing.
- Install in a ventilated location. Do not enclose the supply in a sealed box.
- Confirm each camera's maximum input voltage before raising the output above 12V.
Four cameras. One supply. No voltage-drop callbacks.
