3 Stage Lead-Acid Battery Charger with 2 Stage Charger / Power Supply Mode
SBC - 2130(30A) / 2140(40A) / 2150(50A) 12VDC Series
Description
This series of switching mode 3 stage (IUoU) chargers is designed for wet, sealed (RVLA), calcium-calcium, gel in both SLI (car) and deep
cycle type of lead acid batteries.
The 4 selections of absorption charge voltages and 3 float charge voltage allow a total of 12 combinations of charging profile to cover various
type of lead acid batteries.
Each charger comes with a remote temperature sensor so that the charger can operate accurately over a wide range of ambient temperature
preventing over or under charging the battery.
It also has an automatic soft- start bulk charge with low constant current for deeply discharged battery of less than 10.5V open circuit voltage.
This is to protect the battery from high initial current surge and the battery charger as well. The maximum charge time is limited to11 hours to
avoid over charging .
The unique selectable Power Supply/Charger Mode provides a nominal 12VDC source (per chosen float voltage) for external load and at the
same time not to over charge the battery but keeping the battery fully charged. It is ideal for caravan& other battery back up applications.
With the optional remote control panel, status of the charging( Bulk, Absorb, Float ) can be monitored, output on /off and terminals can be
selected remotely as well.
The streamline, low profile anodized aluminum casing, efficient switching mode circuit design and variable speed fan make it a super quiet and
cool running charger and power supply.
In addition to the standard short circuit, over temperature, reverse polarity protections, it has an OVP (output over- voltage protection) to
ensure complete protection of your battery and connected load.
Zero Voltage Switching
Traditional high frequency SMPS, which rely on generating an AC waveform in the range of 100 kHz to 200 kHz to drive the main power
transformer, have used power transistors to "hard-switch" the unregulated input voltage. During the switching interval, there is a finite period
as the transistor begins to conduct current while the voltage begins to drop. This simultaneous presence of voltage across the transistor and
current through it means that power is being dissipated within the device. In our high current battery chargers, we use the Zero Voltage
Switching (ZVS) technology for power conversion.
ZVS uses circuit resonance to make the transistors switch at a voltage level close to zero, this cuts down radio frequency noise and the stress in
the components. The voltage across all the transistors will drop to zero before the circuit turns on and current starts to flow. So the power
dissipated by the power transistors during the switching period is greatly reduced by 90%, which leads to 2% improvement in the power
supply overall efficiency.
Reducing the power lowers the transistor junction temperature, increases thermal operating margins and, hence, provides a longer life for the
power supply. Not only does a ZVS power supply generate significantly less electrical noise, it achieves greater efficiency, and higher
immunity to the effects of other equipment operating nearby.
This power supply is therefore specifically suitable for in-vehicle, communication, and in applications where low Radio Frequency Interference
is a must.
All values are based on the Standard ambient Temperature 25°C and Pressure 0.1Mpa.
