How to Calculate Input Current for PCR-LE/MA Series

Posted on: June 22nd, 2021 by Doug Lovell
How to Calculate Input Current for PCR-LE/MA Series 22/06/2021
How to Calculate Input Current for PCR-LE/MA Series Before installing PCR-LE or MA Series, you may want to know how much current should be supplied from the distribution board. The best way is to calculate the current consumption (= input current) of your PCR-LE or MA Series. Here are the examples how to calculate the input current based on your output requirement (your outp...

Parallel Operation with Different Power Supply Models

Posted on: June 22nd, 2021 by Doug Lovell
Parallel Operation with Different Power Supply Models 22/06/2021
Parallel Operation with Different Power Supply Models The same model of Kikusui DC power supplies can be connected in parallel. By connecting the signal cables, one unit is set as the master unit and it can control the other units. This operation is called as ‘master-slave parallel operation’. Master-slave parallel operation is not available when connecting the different ...

CC-CV Charging System without Series Diode

Posted on: June 22nd, 2021 by Doug Lovell
CC-CV Charging System without Series Diode 22/06/2021
CC-CV Charging System without Series Diode To charge batteries, it is recommended that you connect a diode in series at an output of DC power supply (See Figure 1). With a diode, constant current (CC) can be properly supplied; however constant voltage (CV) may be unstable if using remote sensing at battery terminals. Without a diode, a high c...
