Switching power supply 18V ZI-3 ZI-3

Note!
*Below 160V input voltage, the power supply will still stabilize the output voltage, but the maximum output current will decrease concurrently with the input voltage decrease.
* Due to the high operating frequency of the inverter, some highly sensitive radio or microprocessor devices may malfunction. It is recommended to install an OP-230 filter (see item 18) between the power supply and the receiver.
*When the load is increased above Imax, the power supply will stabilize the current and the voltage. out will fall. If the voltage out drops to approx. 40%, the power supply will turn off and will be on every 1.5÷2sec. try. The same will happen when connecting a receiver that draws a large starting current (e.g. a cold bulb). If the overload is not too large, the power supply will start after a few attempts (e.g. gradual heating of the bulb filament). If the load is too large, the power supply will keep trying until the load is removed.
