What Is the CHR-120-24?
The CHR-120-24 is a single-output switching power supply designed for standard DIN rail mounting. It delivers 120W of continuous power with a 24V DC output at 5A, making it suitable for a wide range of industrial control equipment.
Key specifications include:
Input voltage: 110–240VAC, 50/60Hz
Output: 24VDC, 5A
Cooling method: Free air convection (fanless)
Protections: Short circuit, overload, over-voltage
Quality guarantee: 2-year warranty
Why Choose a DIN Rail Power Supply?
Unlike traditional power supplies that require screw mounting or enclosure modifications, DIN rail power supplies clip directly onto standard TS-35 rails. This design offers several advantages:
Faster installation – No drilling or extra brackets needed.
Cleaner panel layout – Organized wiring and easier troubleshooting.
Simplified expansion – Adding or replacing units takes seconds.
The CHR-120-24 takes full advantage of this form factor, helping panel builders save time and reduce labor costs.
Key Features That Matter
1. Wide Input Range
The CHR-120-24 accepts 110–240VAC without manual switching. Whether your facility runs on 120V or 230V, this power supply works right out of the box.
2. 100% Burn-In Test
Every unit is tested under full load before leaving the factory. This step catches potential issues early and ensures long-term reliability in the field.
3. Fanless Convection Cooling
No fan means no moving parts. The CHR-120-24 operates silently, consumes less energy, and won't pull dust into your control cabinet - a major advantage in dirty or humid environments.
4. Triple Protection Circuits
Built-in short circuit, overload, and over-voltage protection safeguard your connected equipment. In the event of a fault, the power supply enters hiccup mode and automatically recovers once the issue is resolved.
5. Compact Footprint
With dimensions of just 96mm in height and 65mm in width, the CHR-120-24 leaves plenty of room for other components in crowded panels.
Common Applications
The CHR-120-24 is a versatile power solution for:
PLC control cabinets
Sensor and actuator power
Relay and solenoid circuits
Building automation systems
Small machinery and conveyor controls
Any application that requires stable 24V DC power in a protected indoor environment is a good fit for this series.
Safety and Compliance
The CHR-120-24 is designed for indoor use in protected environments. It carries CE and RoHS compliance, meeting EU standards for safety and environmental responsibility. The label clearly states: Risk of electric shock. Do not open. - a reminder that this equipment should be installed and serviced by qualified professionals only.
Final Thoughts
If you're building or upgrading an industrial control panel, don't overlook the power supply. The CHR-120-24 offers a smart balance of affordability, reliability, and space efficiency. Its DIN rail design simplifies installation, while its fanless operation and protective circuits ensure years of trouble-free service.
Whether you're an OEM, a panel builder, or a maintenance engineer, the 120W DIN Rail Power Supply 24V 5A from CHUHAN is worth a closer look.
