What It Is
The CHFS-120 is a 120W switching power supply that takes 90–240VAC input and delivers 12V DC output at up to 10A.
But the real story is how it's built.
IP67 Waterproof Rating – Fully sealed against dust and water. Rain? No problem. High-pressure hose-down? Fine. Temporary immersion in water? It can handle it. This is not a "keep it under a roof" power supply. It's made to be outside.
Aluminum Shell with Heat Dissipation – The housing is extruded aluminum. It pulls heat away from the internal components and releases it through the surface. No fan. No moving parts. Just silent, reliable cooling.
Ultra-Thin Body – 182mm × 68mm × 42mm. About the size of a thick paperback. It fits in tight spaces where other power supplies won't go.
U-Hook Mounting – Integrated U-hooks on the housing. Screw it to a wall, a pole, or an equipment frame. No extra brackets. No hassle.
Why We Built It
We spend a lot of time talking about EV charging and energy storage. Those are our core products. But when we visited clients in Malaysia and talked to integrators at the Hong Kong exhibition, a smaller need kept coming up:
"Do you have a waterproof power supply for outdoor LED lighting?"
"How about for security cameras? Digital signage?"
"Something that can sit outside in the rain and just work?"
We heard the question enough times that we decided to answer it.
The CHFS-120 is that answer.

Where You Can Use It
The CHFS-120 is not a niche product. It fits a wide range of outdoor and industrial applications:
LED Lighting – Street lights, garden lights, architectural lighting, signage backlighting. Any LED installation that sits outside needs a power supply that won't fail when it rains.
Outdoor Monitors & Displays – Digital signage at bus stops, information screens in parks, outdoor advertising panels. These run for hours every day. They need stable power and weather protection.
Security Cameras – Outdoor CCTV systems are often mounted in exposed locations. The power supply needs to survive heat, cold, rain, and dust. IP67 covers all of it.
Industrial Equipment – Control boxes, sensors, pumps, and other field equipment that operates in wet or dusty environments.
Communication Devices – Outdoor WiFi access points, base stations, and other network gear that needs reliable DC power.
What the Photos Show
We have included photos of the CHFS-120 so you can see the build quality for yourself.
The aluminum housing is cleanly machined. The U-hooks are integrated into the body – no flimsy attachments. The ultra-thin profile is obvious when you see it next to a typical power supply.
What you can't see in the photos is the sealing. But the IP67 rating means every gap is filled, every joint is sealed, and the inside stays dry no matter what the weather does outside.
A Note on Certifications
The CHFS-120 is built to the same quality standards as our charging piles and energy storage systems. We hold CCC, CB, TUV, KC, and SAA certifications for our power electronics. The CHFS-120 follows the same design and testing discipline.
