TDC-9030 Industrial Battery Charger

1. Introduction

The all-digital battery charger (BCU) developed by HANMI TECHWIN is a
device that charges the battery by making high-speed switching method
using 3-phase AC power using IGBT.
BCU (Battery Charging Unit) monitors and protects battery status in real
time to provide optimal operating environment.

2. Characteristics

▐ Simplicity
Charge automatically with battery capacity (AH) and battery rating setting only.
▐ Monitoring charging voltage and current through LCD
Charge voltage, current and charge capacity are displayed, so you can check it
immediately without any additional measuring equipment.
▐ Small, lightweight
It is compact and lightweight because it does not adopt transformer and
large capacitor, and it is easy to handle.
▐ Battery diagnostic function
It continually checks the battery's overvoltage, discharge end voltage and
other conditions to ensure that it is always in top condition.
▐ Equal charge function
Equalization charging is performed when the voltage between the terminals of
the battery and the specific gravity of the electrolyte is not uniform and the
performance can not be fully demonstrated. This function charges the battery
at a constant voltage (117% of the battery rating) during Equalizing time.
When the set time has elapsed and the equal charge is completed, the auto
run parameter is automatically switched to floating charge if the parameter
is set to ON. If it is OFF, the output is stopped.
▐ Recovery charge function
When the battery voltage is below the discharge end voltage (75% of the
rated voltage), it automatically operates in the recovery charge (RC) mode and
is also possible by key operation. The recovery charge is slightly higher than
the battery rated voltage for safety, and when the battery voltage exceeds the
rated voltage, it charges to 115% of the battery rating. When the recovery
voltage and current reaches the appropriate level (voltage is 115% and current
is battery capacity / 50 or less), depending on the setting of Auto Run, it
changes to a floating charge or standby state.
