18V observation circuit

Published:2011/4/1 20:26:00 Author:may | Keyword: 18V, observation

When ±18V battery pack discharge and drop to preconcerted low voltage, Zener diode 1N476 lose control function, Q1 become forward bias, LED is shine. At this time we need to replace the batteries or recharge to them. When battery voltage is normal, Zener diode is in reversal of biasing state, Q1 is cut-off, LED fails to shine, it only consumes current less than 1mA.   (View)
