DC / DC converter 30-90V to 12V 5A step down
- Dimension: 58x40x22mm
- Input voltage range: typically 30-90V
- Output voltage: 12V
- Maximum output current: 5A (4A indicated)
DC / DC converter 30-90V to 12V 5A
It allows you to receive a voltage of 12V using the battery in the bicycle. Thanks to this, we have the ability to power lighting, fans, GPS charging, telephone (via a 12V car charger) and many more.
PINOUT DESCRIPTION
Red: + BAT (input voltage)
Black: common GND for input and output
Yellow: 12V output

Note:
Remember that when connecting other converters to this converter, e.g. lamps, 5V adapters, etc., you need to connect them through a 1-3R 3-5W resistor, which prevents the impulse charging of these devices during the inverter start-up. If there is no such resistor (so-called "soft start"), then when the converter is started (eg through the ignition switch circuit) a very high current will flow at the 12V output and it will damage the converter.
Install the GND from the converter between the BMS and the controller. Thanks to this, the inverter will not discharge the battery to 0. We recommend mounting a 0.5R 3W resistor on the ignition switch circuit to protect the button against burnout due to charging of the inverter input capacitors during connection.
There are 2 ways to connect the inverter in the installation.
1. In controllers activated via the display (e.g. Sinus KT or some versions of Sabvoton) - connect the inverter (red + BAT) via a separate button (switch) to start the inverter independently of the controller. Otherwise, the display will be damaged when you try to connect the inverter between the display and the controller.
2. In controllers activated by using the ignition switch cable - connect the red + BAT to the controller ignition cable, thanks to which, by activating the controller from the button or through the key, the inverter will start simultaneously with the controller.
