Why the SMC 1000 ST?

Ease of Computer Programming

A user-friendly dedicated computer reduces the number of keys required to program the Message Board. The unit provides NTCIP compliant functionality.

LED Lamp Pixel Design

The SMC 1000 ST uses 5 automatic high-intensity, solid-state LEDs per 2-inch pixel. This creates a more uniform light output in each pixel, resulting in increased message definition and distance legibility.

Industrial-Grade Structural Steel Trailer

The SMC 1000 ST uses a durable, industrial-grade trailer system designed to provide years of dependable service. The trailer’s high-quality powder-coat finish, 2″x 4″ 11-gauge steel frame and a 3,500-pound suspension system enhance the overall quality of the unit and has a one piece polycarbonate display window and LED trailer lights inset into trailer frame.

Modular Electronic Componentry

The entire system was developed with the operator/end user in mind. Electronic components are easily replaced, reducing downtime and maintenance costs. This modularity also improves system diagnostics. The system also comes standard with six 6-Volt Deep Cycle Batteries and hydraulic pump and on-board charger.
