LED Gas Price Signs Controller box/Power Supply - 300 Watts

The GLS‑888 300W Controller Box and Power Supply is a commercial-grade solution engineered to power and manage LED gas price signage with unmatched reliability, durability, and efficiency. Built to withstand challenging outdoor conditions and high-demand operating environments, this 300-watt controller box serves as the central power and communication hub for LED pricing displays.

Whether supporting a single unit or powering a large, multi-digit fuel sign configuration, it delivers clean, stable 24-volt DC output, secure data communication, and field-serviceable design in one fully integrated system. Designed for outdoor use, the housing is constructed from thick-gauge powder-coated steel for long-lasting structural strength and resistance to corrosion, salt, UV exposure, and physical impacts. The enclosure is sealed to an IP65 rating, ensuring full protection from dust ingress and direct water spray, including rain, sleet, and canopy runoff.

A gasket-sealed front-access door protects internal components while allowing fast inspection, setup, and service. Internal components are mounted on shock-isolated brackets that protect wiring and power modules from vibration and environmental movement during storms or equipment operation. The internal power supply delivers 300 watts of low-voltage DC output, configured to support a wide range of LED digit combinations—up to twelve 8-inch LED digits or a mixture of numeric and fractional modules. The power output is divided across multiple fused channels, each designed to provide consistent, ripple-free power to connected modules. This ensures uniform brightness across every segment and prevents overloading that can shorten LED lifespan.

Each output is protected by a field-replaceable fuse, accessible from inside the enclosure. This makes maintenance straightforward, minimizing downtime and eliminating the need for full sign disassembly during service visits. With a wide input voltage range from 100 to 240 volts AC and 50/60 Hz frequency support, the unit is compatible with virtually all international power standards, making it ideal for global fuel station deployment. Passive cooling technology is used throughout the system, with integrated aluminum heat sinks and venting pathways that allow silent, fan-free thermal regulation.

This means there are no moving parts, reducing maintenance requirements and extending the life of both power and control components. For communication, the GLS‑888 300W Controller Box is equipped with a secure RS-485 port, supporting direct integration with point-of-sale systems, on-site fuel controllers, and price management software. This allows fuel retailers to implement centralized, automated pricing control from in-store consoles or remote headquarters. For wireless applications, an optional RF module can be added, providing long-range remote control capability using encrypted signals to prevent unauthorized access.

The wireless system is designed to interface with handheld transmitters or cloud-connected control hubs, allowing prices to be updated remotely without the need for physical sign access. Inside the enclosure, a diagnostic LED panel provides real-time data on system voltage, current draw, and fault conditions, aiding in fast troubleshooting and status checks. This helps technicians identify and resolve issues without guesswork, reducing service time and improving uptime. All wiring is UL-rated and clearly labeled to meet electrical code requirements, and a removable terminal block allows safe, tool-free AC connection.

A dedicated grounding terminal ensures proper electrical safety, meeting code compliance for outdoor low-voltage signage installations. Installation is straightforward and supported by a full set of included accessories. The unit ships with universal mounting brackets for wall, canopy, or enclosure mounting, a precision drill template for quick alignment, and a labeled wiring harness for both AC and DC sides.

Gasket-sealed cable entry ports prevent water ingress at cable junctions, and optional tamper-resistant hardware and locking door mechanisms are available for installations in exposed or high-risk areas. These features are especially valuable for unmanned stations, 24-hour locations, and high-traffic urban sites where hardware security is essential. This controller box is purpose-built to manage LED gas price signage of any fuel type, including regular, mid-grade, premium, diesel, flex fuel, biodiesel, or electric vehicle charging rate displays.
