2. ON/OFF CONTROL (CNT)

The ground terminal of remote ON/OFF circuit is connected with -V input terminal. Between CNT and -V input: output voltage is ON

at “low” level or short circuit (0~1.2 V). Between CNT and -V input: output voltage is OFF at “high” level or open circuit (2.4~5.5 V).

When CNT terminal is “low” level, fan out current is 1 mA typical. When Vcc is applied, use 5 V

≤ Vcc ≤ 24 V. When remote ON/OFF

function is not used, please short between CNT and -V input.
