on-line maintenance
> Wide input voltage range(85-300Vac) the power grid is
adaptable
ET48300-005 consists of distribution unit, rectifier module,
conversion module, monitoring module.
The configuration is optional, as table below:

18kW Capacity Rectifier Power System with Power distribution and
Battery Monitor Function
System Configuration
Two operating methods:
(1) AC input: Startup rectifier module after AC powered-on, outputs
-48Vdc, at the same time charge the battery and power the
conversion module, conversion module outputs 220Vac.
Under normal conditions, the parameters of rectifier module and
distribution unit are all under controll of the monitoring module,
operating according to the preset parameters or user’s commands. If
AC mains fault, the battery will power to the system, and continue
outputing - 48 VDC and 220 vac, with the discharge of the battery,
the voltage of the battery starts to descend, when the voltage is
under 43.2 V + / - 0.5 V, the monitoring module send battery
under-voltage signal and close the load output directly, then the
power system will stop working. When external AC mains recovers,
the system will normally work again. (All above monitoring data are
system default values and can be reset by user)
(2) -48V input: No AC current or no AC be connected, access
external power -48V to -48V load port, startup monitoring and
conversion module, 220Vac output.
Temperature compensation function is on by default, which can be
activated or forbiddened by user’s command if necessary. Operation
temperature ≥55℃, the power output of the power supply will be
linearly reduced (@65℃,output power will be 1300W).
