Pulse power supply ZI-22

Pulse power supply ZI-22

ZI-22, 5908312592280

Product description

Output voltage 12 V. Power 30 W.
The switched-mode power supply is used to supply electric and electronic devices that require a stable, filtered supply voltage independent of changes in the mains voltage.

* Below 160V input power supply voltage will continue to stabilize the output voltage, but the maximum output current will decrease concurrent with a decline in input voltage.
* Due to the high frequency converter, some very sensitive radio or microprocessor can operate correctly. It is recommended that you install the filter OP-230 (see item 18) between the power supply and receiver.
* By increasing the load above Imax will stabilize power supply current, but output voltage will decrease. If a outputvoltage falls to about 40% of the power supply is switched off and will be 1.5 ÷ 2sec. sample. Similarly happens when you connect the receiver, which receives a large current boot (ie the cold light bulb). If you're experiencing is not too large, the power supply after a few attempts (eg, the gradual warming-up, the light bulb filaments) runs. If the load is too large to sample the power supply will disconnect the load moment.
