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

Parts¶

• MCU: STM32F072C8T6
• SSRs: CPC1976: Datasheet 2A_rms continuous -> 460W; 1,8KW; zero cross (CPC1976YX6 is non-zero-cross)
• Power measurement: INA228AIDGSR
• 12V/5V: L7987
• 5V I2C: PCA9306DCTR
• High power: SSR-2528ZD3 kann 25A; Steuerung via 5V; habe RA2425-d06, sollte identisch sein.
• Ideal diods: MAX40200 for VDD from VBAT; LM74700 for VBUS with seperate diode
