Installation notes

Connect LED load to the driver via the screw terminals under the removable cover, observing polarity (LED+ and LED–).
Incorrect wiring can damage the power supply and LEDs and is not covered by warranty.
Install with adequate ventilation for heat dissipation and follow the derating curve for higher ambient temperatures.
Installation should be carried out by a qualified electrician.

Typical applications

Use the 75 W 12 V indoor transformer for:

Mid-sized indoor LED lightboxes and menu boards
Longer LED strip lighting runs in retail and commercial fitouts
Indoor illuminated signage, logo boxes and cabinets
Moving sign and display systems that require a 12 V constant voltage driver

Why installers choose the BNV-75-12

More power in one driver – 75 W output lets you run longer LED strings from a single supply.
Easy setup with factory fitted AU plug for quick testing and commissioning.
High efficiency and strong power factor help reduce wasted energy and heat.
Built in protections help safeguard both driver and LEDs in fault conditions.
Compliant for Australian use with AS/NZS 61347.2.13 and relevant EMC standards
