INSTRUCTION MANUAL
5-14. Output Voltage External Control (PV)
(A) Control by External Voltage
Output voltage external control function is provided. Output voltage can be varied by applying an external
voltage (1
－
6V DC) to “PV” terminal and “COM” terminal. Note if an external voltage is not applied, there
will be no output. Please consider the following characteristics below when operating the unit.
Connection Method
Output Voltage Linearity
Note: Only as for the model of 24,36V output, the output voltage is used from 20% to 120%
at the PV voltage is from 1V to 6.0 V
Note: Only as for the model of 48V output, the output voltage is used from 20% to 110%
at the PV voltage is from 1V to 5.5V
Output Voltage Derating
Note: Only as for the type of 48V output, the maximum output voltage is used up to 110% at 90% load current.
* Output voltage usage below 20% is not a guaranteed. There is a possibility that it cannot be use with certain
product. Please conduct a thorough evaluation test before using it.
