Frequently Asked Questions

Can I use the HVG-320-48AB for a 48V LED strip lighting run?

It can fit a 48V LED lighting load when the load is compatible with a 48V driver and stays within 321.6W total output. For strip sizing, use 321.6W divided by your strip's watts per meter to estimate the maximum length, and check your strip rated power per meter before choosing a run length.

Is the HVG-320-48AB suitable for 48V illuminated signage or channel-letter lighting?

This model is intended for 48V lighting loads and provides up to 321.6W at 6.7A, which can suit larger 48V sign-lighting assemblies that match its output. Its IP65 water-resistant housing also makes it more appropriate for signage locations where weather exposure is possible but the unit still needs basic enclosure protection.

Can this driver be used for outdoor architectural lighting at 48V?

It can be used for 48V architectural lighting loads where the fixture or load matches the 24-48V constant-current operating range and the total demand does not exceed 321.6W. The IP65 rating means the housing is water-resistant, so it is better suited to outdoor or damp locations than an indoor-only driver.

How much 48V LED strip can the HVG-320-48AB support?

The maximum available output power is 321.6W, so the length estimate is 321.6W divided by your strip's watts per meter. For example, the driver can support any total strip length that keeps the full run at or below 321.6W, but you should check your strip rated power per meter before sizing.

Can the HVG-320-48AB be used in wet or outdoor locations?

It has an IP65 water-resistant rating, so it is intended for environments where dust and water exposure are concerns, but it is not the same as an IP67 waterproof model. The operating temperature range is -40°C to +85°C, which also supports demanding hot or cold lighting environments.

How does the HVG-320-48AB compare with other HVG-320 voltage options?

Within the HVG-320 range, the main output options are 24V at 321.6W and 13.4A, 30V at 321W and 10.7A, 36V at 320.4W and 8.9A, 42V at 319.2W and 7.6A, 48V at 321.6W and 6.7A, and 54V at 324W and 6A. The HVG-320-48AB is the 48V version, so selection comes down to matching your load voltage first and then confirming the power and current fit.
