DC-DC Step-down Power Supply Module Specifications Input voltage: 9V-90V        The minimum voltage difference between the input voltage and the output voltage          is 4V  (when the output is 5V, the input is DC9V-90V, and when the output is 12V,              the input voltage is DC16V-90V. Output voltage: 12V/5V Maximum output current: 3A (that is, the constant current value is 3A, when the customized voltage is higher than 12V, the output current is less than   3A, the power is not recommended to exceed 30W, 12V and 5V can reach 3A.) Typical operating frequency: 140KHz High efficiency: up to 95% (the smaller the pressure difference, the higher the efficiency) Working temperature: industrial grade (-40℃ to +85℃) Module volume: 42*30*17mm  Product Advantages Frequency reduction at light load to improve light load efficiency. Small standby current. Built-in over-temperature, over-current, output short-circuit protection. Built-in soft start. Constant voltage and constant current output.   Instructions 1.First connect the connection line between the module and the power supply, and then power on. (If the input terminal is connected with electricity, it is prone to sparking, especially when the input power supply voltage is high, the pad of the module may even be burnt). 2.After selecting a suitable power supply, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the device. 3.Connect electrical equipment or (load) to the output of the module.

MKBMS is based on the modular BMS of LTC6811, and is connected to one or more slave boards and integrated boards of different sizes through the ISOSPI interface.  LTC6211 12S Slave BMS Features —— 1. Aluminum alloy PCB, better heat dissipation effect. 2. Compatible with MKBMS and ENNOID BMS. 3. from 5-12 series-connected battery cells per board. 4. 1+4 temperature sensors per slave. 5. Self-powered by the monitored cells. 6. Ultra-low power consumption, sleep mode = 6uA. 7.It can be connected to multiple slave boards to form an integrated board through the ISOSPI interface 8.Daisychain Master ISOSPI communication 9.1.2mV accuracy, -40 to 120C operation 10.33 ohm balance resistors (0.125A capacity) on all channels 11.Scalable & isolated 1000VDC+ 12.Molex SL horizontal connectors for balance & temperature. (Comes with male, female + crimps) Note:　The first temperature channel is used by slave board itself. The following 4 temperature sensors are not in the package lists,  but means an interface to connect 4 temp sensors at most.  Shipping List: 1X   PCBA board LTC6811-12W-AL V1.2 slave board 2X   GH1.25 double head 2P same direction line 1X   HY2.0 single head 5P line 1X   HY2.0 single head 13P line 4X   Nylon column 4X   Nylon nut
