Unit type 2 Function 2.1 Input voltage range ¡The range is from AC85 - 264V or DC(Refer to SPECIFICATIONS). Only AC input is available to comply with agency approval. ¡A low input potential can correspond more than AC85V and DC120V by the option (Refer to 7 Option). The decrease of load factor is needed, and consult us detailed. ¡If the wrong input is applied, the unit will not operate properly and / or may be damaged.
Unit type PBA ¿ PBA300F, 600F, 1000F, 1500F ��� ¡The external output voltage control function is provided. Adjustment of output voltage is possible in 110% from almost 0V of the rated output voltage by following. ¡The output voltage level is able to calculated by 1. However external voltage should not be less than -0.7V and more than 3.0V. Output voltage = 2.

Then use the potentiometer of the mater to adjust output voltage. ¡When remote sensing is used in parallel operation, the sensing wire must be connected only to master. Terminals +S and -S of slave power supplies must be connected to master. ���� ����� � ������ � ¡Output voltage in parallel operation is adjustable by using the potentiometer of the ”master” unit.
5 Assembling and Installation Method 5.1 Installation method ¡The screw should be inserted up to 6mm max from outside of the power supply to keep a distance between inside parts and an isolation.
Instruction Manual Unit type PBA ¡Derating curve depending on input voltage of PBA1500F is shown in Fig.5.3. ¡Warranty PBA50 - 150F : The warranty is 5 years when average ambient temperature of year is Ta=40C or less and load factor is average 50% or less. [%] However, the warranty is 3 years when average ambient tempera- at AC100V 100 ture of year is Ta=50C or less and load factor is series 100%.

Unit type 6.2 Isolation ¡For a receiving inspection, such as Hi-Pot test, gradually increase (decrease) the voltage for start (shut down). Avoid using Hi-Pot tester with the timer because it may generate voltage a few times higher than the applied voltage, at ON / OFF of a timer. If the unit is tested on the isolation between input & output and output & FG must be shorted output, RCG, PGG and AUXG.
