Driver board¶

• One board has 51,24W with the warm LEDs. With LDB350 in general max. 52,8 Watt.
• Supply voltage: 12V-36V
• PWM: 100 ~ 1KHz; 2~10VDC or open circuit

Controller board¶

• Supply voltage: 5V-60V (min/max 9V/36V when power is routed to driver board; min. 12V for VBus 12V)
• Provides VBus 5V or 12V (optional, can be powered externally)
• Switch 4 power lines
  • [VBus, Plant lamp, Media, illumination] or [VBus, Plant lamp, 2 x Illumination]; VBus can be on of the illumination supplies
• Can start via RTC or Button
• Measure power consumption
• 4 PWM signals for regulator board(s)
• External I2C bus for regulator board(s)
• USB port for configuration
• 3 CAN connectors to have it somwhere in the middle of the bus + Display or to have 5V+12V bus

Bulb¶
