Battery Type. A controller designed and approved for battery operation shall not be connected to any other type of power supply or connected to a supply voltage higher than the voltage for which it is designed, except through a converter approved for use with this controller. A. Inductive-Discharge Type. During each shock period, the product of the rectified current in milliamperes capable of being supplied by the controller, and the duration of such period in seconds shall not exceed 3 milliampere-seconds (3 millicoulombs). Between shock periods, there shall be an "off" period of 0.75 second or more, during which time no current is delivered to the fence. B. Capacity-Discharge Type. During each shock period, the product of the rectified current in milliamperes capable of being supplied by the controller, and the duration of such period in seconds shall not exceed 3 milliampere-seconds (3 millicoulombs). Those controllers which deliver their shock intermittently (cyclicly) shall provide an "off" period between shocks of 0.75 second or more, during which time no current is delivered to the fence. Alternating-Current Type. Alternating-current controllers shall not be connected to any supply circuit having different characteristics than the supply circuit for which the controller is designed. C. Intermittent-Alternating Output Type. The maximum current which can be delivered by the controller under any load condition, but not less than 500 ohms, including the measuring instrument connected in series with the fence terminals, shall not exceed 25 rms milliamperes, measured over the shock period. The duration of a shock period shall not exceed 0.1 second, and the frequency of such shock periods shall not exceed one per second. A current of 1 rms milliampere is permissible during the nominally "off" period of the controller. D. Continuous Type. The maximum current which can be delivered by the controller under any load condition, but not less than 500 ohms, including the measuring instrument connected in series with the fence terminals, shall not exceed 8 rms milliamperes.
