Two-Level Brightness Control
- Two preset levels, set at the unit: the paddle control switches between a high and a low brightness setting, so the change happens at the power supply rather than at a wall switch or control panel.
- Where it earns its place day to day: shop windows, restaurant and hotel feature lighting, and advertising light boxes that should stay bright while customers are around and softer after closing.
- Built in, not bolted on: because the two-level function is part of this dimmable led power supply, there is no separate dimmer module to house beside it — useful when a sign box or cabinet is already tight.
- What it is not: the two levels are a fixed high and low choice rather than a smooth fade from 0 to 100%. Run the load at the higher level first to confirm output and wiring, then switch down and check the circuit again.

Interior & Signage Applications
- Shop windows and storefront displays: 24 V strip along shelves, window edges or counters, kept at the higher brightness through trading hours and switched to the lower level once the store closes.
- Advertising signs and light boxes: this indoor led power supply drives single-colour 24 V sign lighting for box signs, menu boards and illuminated panels.
- Home decoration and joinery: cove lighting, display cabinets and niches where a single led strip power supply feeds a short decorative run.
- Commercial interiors: reception desks, showrooms and hospitality spaces where lighting systems need two usable brightness levels rather than full output all evening.
- Signage production: sign makers building compact light boxes usually work in the lower part of the range, while larger illuminated signs move up through the higher ratings as the sign load grows.
Installation & Wiring Notes
- Add up the load before choosing a rating. Total the rated wattage of every 24 V LED strip or sign module on the circuit, then leave headroom for start-up and cable voltage drop instead of matching the rating to the load exactly.
- Match the voltage. Every strip and sign module on the circuit must be rated for 24 V, and the output of the unit must not be fed to a load of a different voltage.
- Mount it where it can breathe. Fix this led switching power supply in a dry indoor position with space around the case for air movement, and keep it out of damp or outdoor locations.
- Wire the input and output before switching on, keep the polarity correct, and keep the low-voltage output runs as tidy and short as the layout allows.
- Test at the higher brightness level first, then switch to the lower level, and check the whole circuit for even light output and any unusual warmth on the case.
- Hand the installation to a qualified electrician and follow the local wiring rules that apply to the project.

We are a China-based LED switching power supply manufacturer supplying wholesale and project buyers. Our portfolio covers a wide range of series, so you can source stable constant-voltage drivers, 12V/24V auto-sensing units, fully potted waterproof models for outdoor signs and landscape lighting, brightness-controlled units for advertising signs, and magnetic-mount versions for secure indoor installation — all from one supplier. Wholesale supply is available. Share your application and voltage requirement, and we will point you to the series that suits your order.
FAQ
Q1. What LED loads can this power supply run?
It is designed for 24 V loads: single-colour LED strips, lighting systems and advertising signs. This 24 V LED power supply suits strip runs, cove and cabinet lighting, sign boxes and display lighting in indoor projects. Every load on the circuit must be rated for 24 V, and the combined wattage has to stay inside the rating you select.
Q2. Is the ZUN Series dimmable, and do I need to add a wall dimmer?
Brightness is controlled on the unit itself. Two levels, high and low, are switched with the paddle control, so this dimmable led power supply does not need a wall dimmer or a separate dimming module for two-level operation. If a project calls for smooth dimming or a control signal from another system, describe the setup to us and we will tell you what is possible.
Q3. Can one unit power several short runs of LED strip?
Yes, as long as the combined wattage of the runs stays inside the rating you choose. Add up the wattage, leave headroom for start-up and cable drop, then select from 60 W to 400 W. A single 24 V led strip power supply can therefore feed a display wall or a set of shelf runs instead of being limited to one strip.
Q4. Can the ZUN Series be installed outdoors or in a damp area?
No. This indoor led power supply is made for interior projects and home decoration, so it belongs in a dry, protected position with air around the case. Outdoor signs, billboards and wet or dusty locations need a sealed, weather-protected unit instead. Tell us the installation conditions and we will point you to the right option in our range.
Q5. Is the output voltage adjustable?
No — the ZUN Series is built as a fixed 24 V output, so it is matched to loads rated at 24 V. Power ratings run from 60 W to 400 W at that voltage. Send us the total load and the application, and we will confirm which rating this led switching power supply should be ordered in.
Q6. How should unused units be stored before installation?
Keep them in the original cartons in a dry, ventilated store, away from damp floors and direct sunlight, and leave the terminals protected until the unit is fitted. Avoid dropping or knocking the case, since the transformer and board sit inside a rigid enclosure. If you hold several ratings on the shelf, fit the oldest stock first.
