LPV vs LDV: How to choose a stable and durable switching power supply for an LED project?

LPV switching power supply

Product Description

The LPV series features a long, white engineering plastic casing and is a low-power, economical constant voltage power supply. Its core value lies in its "lightweight and economical design + IP67 protection + coverage for small to medium power applications.

Power Coverage: 18W–150W: Precisely matched for indoor and outdoor small to medium power scenarios, common specifications include 18W, 36W, 60W, 100W, and 150W, all providing 12V/24V output.

IP67 Fully Sealed Plastic Shell: Although it has a plastic shell, the potting and sealing process achieves an IP67 protection rating (completely dustproof and capable of short-term water immersion). This allows the LPV to be used not only in dry indoor environments but also safely installed in semi-outdoor corridors, under awnings, and in damp environments such as bathrooms with condensation.

Small Size and Light Weight: The long, rectangular design makes it easy to conceal within light troughs, joists, and advertising lettering, making it particularly suitable for installations with limited space.

Natural Insulation, No Grounding Required: The plastic shell is non-conductive, meeting Class II electrical requirements, eliminating the need for a grounding wire and reducing installation time and costs.

The Practical Problems Solved

Concern	Answer
Can a plastic-cased power supply be used under a semi-outdoor awning?	Yes. The LPV series features an IP67 rating, making it rainproof and dustproof; however, please avoid prolonged exposure to direct sunlight or extreme heat.
I need a 60W power supply for an LED strip. Do you have one with a suitable wattage?	Yes. Multiple power settings are available, ranging from 18W to 150W.
I have a limited budget, but I don't want to sacrifice waterproofing performance.	The LPV series is the top choice for indoor and semi-outdoor applications in terms of cost-effectiveness, offering savings of over 30% compared to aluminum-cased models of equivalent power output.

LDV switching power supply

Product Description

Featuring an aluminum alloy housing, the LDV series is a high-power, industrial-grade constant-voltage power supply. Its design philosophy centers on the principles of "superior thermal management, rugged durability, and suitability for harsh outdoor environments.

Power Range: 40W–400W:Covering a comprehensive spectrum from low-to-medium power to industrial-grade high power, the series includes mainstream specifications of 40W, 60W, 100W, 150W, 200W, 300W, and 400W, offering constant-voltage outputs of 12V and 24V.

Aluminum Housing + IP67 Rating:The aluminum alloy housing not only boasts an exceptionally high thermal conductivity but also utilizes a fully sealed potting process to achieve an IP67 protection rating. This ensures reliable performance even in harsh outdoor conditions involving heavy rain, high humidity, and salt-mist exposure.

Shock and Vibration Resistance: The robust aluminum housing structure is capable of withstanding continuous vibrations within street light poles, the compressive forces exerted on in-ground lighting fixtures, and the mechanical shocks encountered during the installation of large-scale display screens.

The Practical Problems Solved

Concern	Answer
In an outdoor environment with summer temperatures reaching 60 Degree, will a 300W power supply trigger thermal protection?	The aluminum casing ensures rapid heat dissipation, and—combined with a wide-temperature design—enables reliable operation.
Roadway lighting requires vibration resistance; is this suitable for that application?	Aluminum housing with internal potting for secure fixation; meets automotive vibration test standards.
