Tycon Power TP-BC48-300 - Manual (Page 3)

 INSTALLATION:
Before plugging in the model to an AC outlet, please make sure that the proper input
voltage is selected on the rear of the unit. Select 115V for 100/110/120 AC operation
or 230V for 200/220/240 AC operation. The factory default setting is 230V.
Then, connect your device to the LOAD terminal and connect a lead acid battery to
the BATTERY terminal, make sure the polarity of battery is correctly connected,
select WET for wet battery, GEL for GEL or AGM battery.
You may connect a solar panel or wind turbine to the BATTERY terminal at the same
time by connecting a solar panel or wind turbine controller to the battery terminals,
please make sure it is as the same polarity as battery.
Now, plug in the power cord to AC outlet, turn the PWR switch to the “ON” position.
Turn on your device now.
 OPERATION:
The PS works as a DC UPS (Uninterruptible Power Supply) or as a backup power
supply system. When AC power is applied normally, the model offers a regulated
48V DC output at LOAD terminal for devices and a charging current output on
BATTERY terminal for charging a lead acid battery at the same time. Once AC fails,
the battery will replace the AC to power the model immediately without interruption.
The LOAD terminal will remain at 48VDC output for a while till the battery voltage
reduces to lower than 40V, the duration time depends on the volume of the battery
and the size of the load. When AC returns, AC takes over the battery to power the
load automatically, and start to charge the battery.
