What is 24V 4A UL Class 2 Power Adapter?

UL 96W Class 2 Adapter is a safety classification defined by UL (Underwriters Laboratories) and the National Electrical Code (NEC) for power supplies with inherently limited energy output. Key characteristics:

Parameter	UL Class 2 Limit	This Adapter (24V 4A)
Output Voltage	Max 50V DC	24V DC
Output Power	Max 100VA	96VA (96W)
Output Current	Limited to safe value	4A (within limit)
Energy Limitation	Inherently limited (no external fuse needed downstream)	Yes – internal current/power limiting
Wiring Requirements	Reduced wiring methods per NEC	No secondary overcurrent protection required

Benefits of UL Class 2:

Eliminates need for secondary overcurrent protection (fuse/circuit breaker) downstream of the adapter
Reduces fire and shock hazard through inherent energy limitation
Simplifies wiring and lowers installation cost in LED lighting, security and IoT systems
Mandatory for many UL-listed luminaires, surveillance systems and connected devices in North America
Wiring can use Class 2 cables (e.g., CL2, CL2P, CL2R) with reduced conduit requirements

AC Input Connector Options

IEC Type	Protection Class	Grounding	Best For
IEC320-C8	Class II (double insulated)	No earth pin	Lightweight designs, portable equipment, consumer electronics, no ground needed
IEC320-C6 (cloverleaf)	Class I (with earth)	Earth pin	Industrial equipment, metal enclosures, equipment requiring ground connection
IEC320-C14	Class I (with earth)	Earth pin	Rackmount, higher power systems, permanent installations

INFO Select IEC type based on your equipment’s protection class and grounding requirements. C8 = Class II no ground; C6/C14 = Class I with ground.

Applications

Application	Typical Devices	Power Need	Why UL Class 2
LED Lighting	LED strips, LED luminaires, signage, display lighting	24V / 60-96W	NEC Class 2 wiring, reduced conduit, UL-listed fixtures
Security & CCTV	IP cameras, DVR/NVR, access control, alarm systems	24V / 48-96W	No secondary fuse needed, safe low-voltage wiring
Connected Home / IoT	Smart home hubs, sensors, gateways, home automation	24V / 24-96W	Inherently safe, reduced shock/fire risk
Telecom & Networking	Modems, switches, routers, communication modules	24V / up to 96W	Clean regulated power, global certifications
Industrial Controls	Small motors, actuators, controllers, sensors	24V / 48-96W	Class 2 limited energy, simplified wiring

Q1. Why is 96W the limit for a 24 Volt Power Adapter?

A. Per the UL 1310 and NEC standards, a Class 2 power source must not exceed 100 volt-amperes (VA). For a 24V system, this calculates to roughly 4.0 Amps (96W). Our adapter provides the absolute maximum power possible while staying within this critical safety threshold.

Q2. Does using a 24V 4A Power Adapter really reduce my installation costs?

A. Yes. In many commercial and residential jurisdictions, the National Electrical Code (NEC) allow Class 2 wiring to be installed without the same heavy-duty conduit or fire-rated raceways required for standard Class 1 circuits. This can save you between 20% to 50% on labor and material costs for low-voltage wiring.

Q3. I see the factory is Zhenhuan but the brand is Keysun. Will this pass an audit?

A. Absolutely. Zhenhuan is our manufacturing base, and Keysun is our brand and certification entity. All UL files (e.g., E497389) link these two together. We provide all necessary technical documentation and authorization letters to ensure your procurement and inspection teams have 100% confidence in the traceability of the product.
