# SPARK Flex Specifications The following tables provide the operating and mechanical specifications for the SPARK Flex Motor Controller. {% hint style="danger" %} DO NOT exceed the maximum electrical specifications. Doing so will cause permanent damage to the SPARK Flex and will void the warranty. {% endhint %} ## Main Electrical Specifications

Parameter	Min	Typ	Max	Units
Input Voltage (Nominal)	-	12	-	V
Operating Voltage Range †	6	-	24	V
Absolute Maximum Supply Voltage	-	-	30	V
Continuous Output Current ††	-	-	60	A
Peak Current (2 second surge)	-	-	100A	A


†	6 V minimum for 5 V Data Port output. 4.5 V minimum before full brownout.
††	Continuous current duration tested at 3 minutes.

## PWM Input Specifications

Parameter	Min	Typ	Max	Units
Full-reverse Input Pulse	-	1000	-	μs
Neutral Input Pulse †	-	1500	-	μs
Full-forward Input Pulse	-	2000	-	μs
Valid Input Pulse Range	500	-	2500	μs
Input Frequency	50	-	200	Hz
Input Timeout ††	-	50	-	ms
Default Input Deadband †††	-	5	-	Hz
Input High Level	0.5	0.7	0.9	V


†	Neutral corresponds to zero output voltage (0 V) and is either braking or coasting depending on the current idle behavior mode.
††	If a valid pulse isn't received within the timeout period, the SPARK Flex will disable its output.
†††	Input deadband is added to each side of the neutral pulse width. Within the deadband, output state is neutral. The deadband value is configurable using the REV Hardware Client or through the CAN interface.
