Works with 12, 24, and 36 Volt Battery Packs: Multiple Voltage rated speed controller can be used with 12 Volt, 24 Volt, or 36 Volt battery packs.

Under Voltage Shutoff:  This controller's under Voltage shutoff value is 10 Volts ± 0.5 Volt. This shutoff value is too low for under Voltage protection of 24 and 36 Volt battery packs so using a Voltmeter to monitor the battery pack Voltage is recommended when using it with 24 and 36 Volt battery packs.

Requires Heavy-Duty Switch or Contactor: This controller requires and external switch or contactor to turn it on and off. A heavy-duty disconnect switch such as item # SWT-700 or SWT-705 or power contactor such as item # RLY-24150 or RLY-36150 is needed to turn this controller on and off.
