EVERSECU 18 Channel 12V 20Amp DC Metal Boxed Cabinet Regulated UPS Power Supply Unit with Backup Battery Link
Quick take
This 12V regulated UPS-style power supply is built for security systems that need uninterrupted power during outages, with auto switching to a separate 12V battery (battery not included). It combines 18 independent output channels and per-channel protection for wiring multiple CCTV and access components in one metal, lockable cabinet. The main caveat is that the cooling fan can run a lot under heavier loads, so it may not be ideal if you are placing it in a living space.
Pros and cons
Pros
- 18 independent output channels, designed to run multiple 12V security devices from one unit
- UPS backup function with seamless switchover to a 12V SLA/AGM battery when AC fails
- Metal enclosure with a lock for tamper resistance in security installations
- Regulated output with low ripple (≤120mVpp) to support clearer CCTV footage and steadier alarm/access operation
Cons
- Battery is not included, and backup runtime depends on the 12V battery capacity you install
- Cooling fan activity can be noticeable when running heavier loads (for example, IR camera loads)
- You must confirm your devices are compatible with adjustable 11.4 to 15V output settings (factory set around 13.2V)
What buyers think
Buyer-review evidence is limited but points to a consistent theme: the unit can power multiple 12V security-related loads from one box and provide enough battery-backed runtime to bridge an outage until backup power is running. Users also mention that the fan may run frequently or audibly when driving infrared or other higher-demand loads.
What it is and how it fits security systems
The EVERSECU 18-channel 12V UPS power supply is intended for CCTV, burglar alarms, and access control systems that benefit from centralized, regulated power and battery backup during AC outages. Instead of running devices from separate supplies, it packages both regulated DC output and UPS switchover behavior in a single metal cabinet, with multiple outputs so you can distribute power across different devices.
Key features that matter for daily use
UPS auto switchover for outage protection
When AC power drops, the unit switches to battery power (battery sold separately). This is the core feature for security buyers who want cameras, alarm panels, and access components to stay online during outages rather than rebooting or shutting down.
18 outputs with per-channel protection
It provides 18 independent channels with a total output current of 20A nominal (with a 25A max) and protection per channel using resettable PTC fuses rated at 2A per channel. Practically, that means you can wire multiple devices without one device causing broad issues across the entire output bus.
Regulated 12V output with low ripple
The output voltage is adjustable from 11.4V to 15V, and it is factory set around 13.2V. The design also targets low ripple and noise (≤120mVpp), which is especially relevant for camera performance and stable operation of security electronics.
Dedicated charging designed for common security batteries
Charging current is specified at 300mA, and the unit is optimized for 12V sealed lead-acid (SLA), AGM, or gel cell batteries. Recommended battery capacities are listed as 7Ah to 20Ah, which helps you choose a backup duration that matches your expectations for outages.
Metal, lockable cabinet for tamper resistance
The enclosure is metal and includes a lock, a useful combination for security deployments where you want the power infrastructure protected from casual tampering.
Pros and cons in plain terms
Pros
- One-box power distribution: 18 channels help you consolidate power for cameras, alarms, and access components.
- Security-focused stability: regulated output with low ripple and UPS switchover behavior.
- Installation-friendly enclosure: metal cabinet with lock improves physical security.
- Per-channel protection: resettable PTC fuses (2A per channel) help manage individual device issues.
Cons
- Plan for the battery: battery is not included, and backup time depends on the battery capacity you install.
- Fan noise may be a factor: buyers note the cooling fan can run often during heavier loads, and it can be audible within a cabinet.
- Voltage setting matters: because output is adjustable, you should verify your connected devices expect compatible 12V behavior (factory set near 13.2V).
Who should buy
- You are building or upgrading a security system with multiple 12V devices and want centralized power plus battery backup.
- Your devices benefit from a regulated 12V supply and you want low ripple for better camera stability.
- You prefer a metal, lockable enclosure for a cleaner, more tamper-resistant install.
- You are comfortable selecting a compatible 12V SLA/AGM battery sized for your expected outage window.
Who should avoid it
- You need a very quiet UPS solution for placement in a living area, since the fan can be noticeable under load.
- You do not plan to use a compatible 12V sealed battery, because backup relies on a battery you purchase separately.
- You have security devices that require a strictly fixed voltage and you are not willing to verify compatibility with the adjustable output range.
Battery backup expectations (how to think about runtime)
The unit is specified for lead-acid battery compatibility and lists an 8-hour runtime, but that kind of number only applies under specific load conditions and battery capacity. If your cameras include infrared illumination or other higher-demand components, runtime can change. The safest approach is to estimate your total current draw across the devices you will power, then pick a battery capacity (7Ah to 20Ah is recommended) that matches the duration you need during an outage.

FAQ
Is the battery included with the EVERSECU UPS?
No. The UPS unit is designed to work with a separate 12V SLA, AGM, or gel cell battery, and the battery is not included.
How many devices can I power?
It has 18 independent output channels, with per-channel PTC fuses rated at 2A and a total output current of 20A nominal (25A max). Your actual number of devices depends on each device’s current draw.
What voltage does it output?
The output voltage is adjustable from 11.4V to 15V and is factory set around 13.2V. Check your devices to ensure they are compatible with this range.
Does it switch to battery power during an outage?
Yes. It is a UPS-style design intended for seamless switchover to battery power when AC fails.
Is the fan always on?
Cooling behavior depends on load. Some buyers report that the fan can run frequently or be audible during heavier security workloads, such as infrared camera loads.
What kinds of security systems is it meant for?
It is designed for CCTV, burglar alarms, and access control systems that use 12V power, including setups with multiple cameras and access readers.
What is the input voltage range?
It supports a wide AC input range (90 to 264VAC) across 47 to 63Hz, which can be helpful for installations with varying mains power.
Bottom line
The EVERSECU 18-channel 12V UPS power supply is a strong fit for security installers and homeowners who want centralized regulated power with battery backup for multiple devices. If you plan to use a compatible 12V sealed lead-acid battery and you are okay with the possibility of an audible cooling fan under heavier loads, the 18-channel, per-channel protected design can simplify wiring and keep cameras, alarms, and access control running when AC power fails.
