Mk9 is a VESC capable of handling up to 200VDC, succeeding previous Mk5, Mk6 , Mk7 & Mk8
Warning: Using higher voltage brings new safety hazards. No data is yet available, so use at your own risk!!!
What's new:
Now up to 40S capable
More powerful aux. 12V rail
Better accuracy for voltage readings
Single UART port instead of two, new JST GH 3 pin for 5V lighting
New aluminum case with better accessibility and ergonomics (still backward compatible with MK8 mounting pattern)
Copper aluminum case option for up to 40% increased thermal performance
Roll-to-start feature
N.O. button instead of N.C. (Still possible to use an N,C. button by removing a jumper)
Description:
Single motor controller equipped with 6 x TOLT MOSFET
Low side shunt current sensor
Up to 200V tolerant ~40S capable
75A Battery, 150A Phase (XT60 battery connector limited to ~60A continuous, AWG 12 wires to ~80A continuous,) Note that many others ESC have exaggerated specs! 150A is for guidance only
Optional Bluetooth module or MK9-SHIELD (mounted separate onto the removable cover)
Accelerometer IMU (LSM6DS3)
Automatic & manual shutdown (requires external N.C. momentary button, hibernation current ~30uA, long press to turn ON & OFF)
DC Input 12 Gauge silicon wire to XT60 Male
Phase Output 12 Gauge silicon wire to 4mm Female Bullet connectors
ADC1 and ADC2 internally equipped with 10k Ohm pulldown resistors
Aux. power outputs:
12V : 1A
3.3V : 2A
5V : 2A
Enclosure dimensions: 58mm x 68mm x 18mm
Connectivity: JST-GH-1.25mm (CAN, SWD, UART, HALL, ADC, SERVO, 12V), USB-C
PICTURE TO COME
Four 4.25mm holes are available to interface with external devices ( CAN, power switch, sensors, HALL) Use preferably with 3.7mm diameter Julet connector (HiGo Mini-B for ebike)
For application that does not require a 30s cell count e.g.: 18S, 20S, 24S, 28S or 40s you can request an MK9 with different voltage MOSFET, see table below:
Power ON/OFF button: Latching type button is supported, change the setting in VESC-tool->app settings->general->shutdown mode->Always OFF
5 to 10 seconds are needed at startup for the VESC to respond to the button input
Any VESC need precharge! Failure to do so might damage the MK9, especially at 30s+!
