Power Supply Topic Cluster

We organize power supplies by where and how they are used, so buyers can jump straight to the right category.

Where Our Power Supplies Are Used (Applications)

Industrial Automation

PLCs, HMIs, sensors, conveyors and robotic cells on DIN rail or enclosed PSUs.

Building Automation

Access control, HVAC controllers, fire and security panels with stable 24V DC.

Security & Surveillance

CCTV cameras, NVRs and PoE switches — 12V/24V adapters and centralized PSUs with UPS backup.

Telecom & Network

CPE, ONU, routers, small-cells and 5G gateways on wall/desktop adapters and PoE.

Retail & Banking

POS terminals and ATM card readers on 24V DC supplies with surge protection.

Medical & Instrumentation

Lab and diagnostic equipment needing regulated, low-ripple DC (custom options available).

Comparison: Choose the Right Form Factor

DIN Rail vs Enclosed Power Supply

Both are metal-cased industrial PSUs. DIN rail clips onto a 35mm rail for fast panel mounting and hot-swap service — ideal for control cabinets. Enclosed (chassis) units screw to a surface and suit fixed machinery with more space. Same 75W–1000W range; choose by mounting method.

Adapter vs Industrial Power Supply

Adapters (wall/desktop) power consumer and network gear (routers, CCTV, POS, ATM). Industrial PSUs are metal-cased DIN-rail/enclosed units for 24/7 factory and telecom loads with stronger protection and wider operating ranges. Match the unit to duty cycle and environment.

Frequently Asked Questions

What is an industrial power supply?

An industrial power supply converts AC mains into a stable, regulated DC output built for continuous 24/7 duty in harsh environments. It has a wide input range (typically 85–264V AC) and built-in protection against short circuit, overload, over-voltage and over-temperature. XGW builds 75W–1000W enclosed and 25W–1000W DIN rail units, UL/CE/CB certified.

How to choose a DIN rail power supply?

Size it to your load's continuous wattage with 20–30% headroom, confirm the DIN rail (35mm TS-35) form factor and input range, then verify protections (OVP/OCP/OTP) and the certifications your market requires. Our DIN rail selection guide walks through the steps with a sizing example.

What is a DIN rail power supply used for?

DIN rail PSUs mount on standard 35mm rails inside control cabinets for PLCs, HMIs, sensors, relays, building automation and telecom/network equipment. They are the default choice when you need tool-free rail mounting and a compact, replaceable unit in panel boards.

What is the difference between a DIN rail and an enclosed power supply?

Both are metal-cased industrial PSUs. DIN rail units clip onto a 35mm rail for fast panel mounting and service; enclosed (chassis-mount) units are screwed to a surface and suit fixed installations with more space. Pick DIN rail for control cabinets, enclosed for machinery and fixtures.

What is the difference between an adapter and an industrial power supply?

Adapters (wall/desktop) power consumer and network gear — routers, ONU, CCTV cameras, POS and ATM. Industrial power supplies are metal-cased, DIN-rail or enclosed units engineered for 24/7 factory and telecom loads, with stronger protection, wider operating ranges and higher surge immunity.

Do you manufacture AC/DC power adapters in China?

Yes. XGW is an AC/DC adapter manufacturer in China producing 5W–150W wall and desktop adapters (12V/24V, 45W/65W/120W/150W) plus USB-C PD chargers, certified to UL/CE/CB/PSE/SAA and shipped OEM/ODM to 50+ countries. See our CPE & network adapters.

What CCTV power adapter do you supply?

We supply 12V and 24V CCTV power adapters, centralized CCTV PSUs (1–32+ cameras) and PoE PSUs for IP cameras, with optional LiFePO4 UPS backup for 24/7 surveillance. Details in our CCTV power guide.

What certifications are required for an industrial PSU?

For most markets: safety (UL 62368-1 / IEC 62368-1, EN 60335), EMC (CE), and CB for multi-country acceptance. Outdoor or IPC units may need IP ratings; medical or railway apps need additional standards. XGW holds UL/CE/CB/PSE/SAA and can support customer-specific marks.

Can you make a custom power supply to my specification?

Yes. XGW supports OEM/ODM from a 500-unit MOQ — custom output voltage, connectors, dimming, housing and firmware — with samples in 3–7 days and certified production. Start from our custom AC/DC power supply page.

Are your power supplies suitable for telecom and UPS backup?

Yes. Beyond DIN rail and adapters, XGW supplies 48V telecom LiFePO4 batteries and UPS lithium replacement, and we engineer PoE and security-surveillance PSUs with battery backup. For battery backup see our 48V telecom battery range.
