1. APPLICATION
:
This automatic battery charger has been designed to continuously charge
a Lead-Acid Battery to start engine generator set by the switching mode
power supply (SMPS)
,
which is most essential to give emergency power to
the equipment in the event of main power failure.
2. FEATURES :
2.1. Charges batteries with constant voltage and current.
2.2. Protection against the reverse property of battery.
2.3. Current limited automatically (does not require disconnect on engine crank).
2.4. Low ripple voltage (below
±
1%).
2.5. Durable for continual use at maximum capacity by wide heat radiation area.
2.6. Durable under a damp and vibrating environment by silicon coating.
2.7. Useable for 50Hz & 60Hz.
2.8. Equalizing and floating charging.
2.9. High efficiency (over 80%).
2.10. Battery discharge protection at AC input power off (Patented).
2.11. Adopted Switching Mode Control method (SMPS).
2.12. Easily field adjustable without battery connection.
