320W IP67 IP65 UL Waterproof LED Power Supply

Outdoor lighting failures often stem from poor power sealing. KSPOWER H/HO/HT/HP Series waterproof LED drivers are IP67-rated, providing a hermetically sealed defense against rain, humidity, and dust. Ranging from 40W to 320W, these constant voltage power supplies are the “gold standard” for landscape and facade projects where reliability is non-negotiable. UL/CE/FCC certified, they offer a maintenance-free lifespan, ensuring your professional reputation remains as solid as our power delivery.

The H/HP/HO/HT Series 300W/320W Outdoor Waterproof LED Driver is a professional-grade constant voltage power supply engineered for the most demanding outdoor LED installations. Operating across a universal AC input range of 100–277V, the H Series delivers reliable constant voltage power at 24V, 36V or 48V DC — making it the ideal power solution for landscape lighting, building facades, LED signage, tunnel lighting, parking areas and a wide range of architectural LED projects.

Constructed with a super-compact extruded aluminum enclosure, the H Series weighs just 1.68 kg per unit while delivering up to 320W of continuous power. The precision-engineered thermal management system enables full-load operation at temperatures from -40°C to +50°C, making these drivers suitable for cold-climate installations such as Nordic outdoor lighting, refrigerated warehouse LED lighting, and hot-climate outdoor applications alike.

Every H/HP/HO/HT Series driver undergoes 100% factory burn-in testing before shipment, ensuring zero defect rate at delivery. Built-in auto-reset protection circuits — covering over-voltage (OVP), over-current (OCP), over-temperature (OTP), over-power (OPP) and short-circuit (SCP) — protect both the driver and connected LED load against damage from abnormal operating conditions, automatically resetting once the fault clears.

Four Function / Dimming Versions

Function Version	Model Prefix	Description	Typical Application
Non-Dimmable (Standard)	KS-320A-XX	Constant voltage output only, no dimming	Signage, general landscape, basic installations
TRIAC / Phase-Cut Dimmable	KS-320A-XXT	Leading-edge / trailing-edge TRIAC dimming, flicker-free 1%-100%	Hotel exterior, residential landscape, ambiance lighting
0-10V 4-in-1 Dimmable	KS-320A-XXO	0-10V / 1-10V analog dimming, smooth 1%-100% control	Commercial building automation
5-in-1 Dimmable	KS-320A-XXP	0-10V + TRIAC + PWM + Resistance in one unit	Multi-protocol projects, global distributor stock simplification

All four versions share the same mechanical dimensions (258×68×41mm), IP rating (IP65/IP67) and certifications, allowing flexible inventory management with one mechanical SKU.
