(2) 10% of current limit setting value foldback.
(3) Specification applies to internal power module and results in unit shutdown. To recover, disconnect a-c input, wait about 40 seconds, then reconnect
a-c input.; to recover immediately, toggle the RC control signal OFF, then ON (see Remote On-Off Input, above).
(4) Ripple & noise = 1.5 x indicated values for Ta = -10°C to 0°C. Values shown are satisfied for 0 to 100% load, 0 to 65°C, measuring bandwidth ≤ 100MHz.
(5) Minimum input impedance of 1 Megohm required for voltage measurement instrument.
(6) To calculate temperature compensation for cell voltage other than 2.23V, see Section III - Using Temperature Compensation for Lead-acid Battery.
(7) Output disconnected for output current > 1.45 x rated current limit.
(8) Alarm activates upon detection of missing a-c input, charger not operational, or output current falls below 1% of charger maximum current limit.
