12v GSL Advanced Micro-Controlled Electronic Brake Controller. The EBC-12 is an advanced electronic brake controller designed for trailers. Utilizing microprocessor-based technology, these controllers offer precise braking control. They are suitable for both single and dual axle trailers operating on negative earth (ground) systems.

Specifications

• Minimum Input Voltage: 9 VDC
• Nominal Input Voltage: 12 VDC
• Maximum Input Voltage: 15 VDC
• Output Voltage: 12V
• Current Load: No load - 30 mA; Maximum load - 2 Axle / 12A Avg
• Dimensions: 40mm x 80mm x 125mm
• Weight: 270gm

Features

• Digital display for accurate setup and ease of use.
• Selectable three-position ramp-up for brake speed.
• Easy adjustment via two push-buttons.
• 2 Axle 12A output capability.
• Open circuit and overload indication and protection.
• Top or bottom mounting via the multi-position bracket.
• Convenient over-ride slide lever.
• Can be mounted at any angle.

Installation Instructions

1. Disconnect Vehicle’s Negative Battery Terminal: Ensure the vehicle is off and disconnected from its power source.
2. Mounting Location: Choose a solid surface that is easily accessible to the driver. Secure the mounting bracket with self-tapping screws, ensuring not to over-tighten.
3. Wiring Connections:
   • White Wire: 0V DC (Ground)
   • Blue Wire: Brake (Connect to the trailer brake wire)
   • Black Wire: +VDC (Power supply line)
   • Red Wire: Brake Switch (Connect to the cold side of the brake light switch)
   Important: Ensure the unit is properly grounded to prevent intermittent operation or failure. Do not connect the black wire to the fuse panel or accessory wiring to avoid damage.

Note: An external 15A fuse must be fitted on the blue wire (not supplied).

Set-up & Operation

• Setting the Braking Force - Adjust the brake intensity using the up and down arrow buttons in 01 increments, from 15 up to a maximum of 99. A low setting or "O.C." display indicates a low braking force or open circuit. To troubleshoot, set the control to 50 and retest. If "O.C." persists, check for wiring issues or brake coil faults

• Ramp-Up Feature - Adjust the ramp-up feature by pressing both face buttons together. There are four settings:

• 00: No ramp-up (instant braking)
• 01: Fast ramp-up
• 02: Medium ramp-up
• 03: Slow ramp-up

This feature allows for gradual increase in braking force up to the set level of intensity, suitable for different towing conditions.

Fault Indication

• O.C.: Indicates low brake force or open circuit. Check for disconnected wires or faulty brake coils.
• O.L.: Indicates overload. Reduce load or check for short circuit on output.
