SBC-5925: 3 STAGE DC-DC CHARGER.
DESIGNED TO CHARGE AUX BATTERIES WITH AND WITHOUT AN IGNITION TRIGGER.
NOTE:
BATCH STARTING WITH SERIAL#s G5016
VEHICLES WITH A LOW VOLTAGE CHARGE ALTERNATOR WILL ONLY BE ABLE TO USE THE AUTO START MODE IF THE
CHARGE VOLTAGE TO THE UNIT IS ABOVE 13.4V (START CHARGE = 13.4V (26.8V) STOP CHARGE = 12.8V (25.6V))
UNITS FROM THIS BATCH CAN STILL BE USED IF INPUT VOLTAGE IS < 13.4V BY USING THE IGNITION MODE
NOTE:
BATCH STARTING WITH SERIAL#s 1516
VEHICLES WITH A LOW VOLTAGE CHARGE ALTERNATOR CAN USE BOTH MODES. IF USING AUTO START MODE, CHARGE
VOLTAGE SOURCE MUST BE ABOVE 12.8V (START CHARGE = 12.8V (25.8V) STOP CHARGE = 12.2V (24.6V))
10 SECOND DELAY FOR ALL SET POINTS FOR THIS BATCH.
SPECIFICATIONS:
•
9-32V input range (suitable for 12V or 24V input to 12V output but NOT 24V output):
•
70 mA current draw on input side when not charging and unit on in AUTO START MODE.
CHARGING STATUS LED
BULK MODE
(FAST FLASH): VOLTAGE WILL KEEP RISING UNTIL ABSORPTION VOLTAGE IS REACHED.
SOFT START:
(FAST FLASH): IF IN FLOAT, OUTPUT IS 1.15A UNTIL BULK CAN BE REACHED, THIS IS IF OUTPUT BATTERY IS
LOW OR THERE IS A HIGH LOAD.
ABSORPTION MODE
(SLOW FLASH): VOLTAGE WILL STAY CONSTANT AT SET POINT AND CURRENT WILL DECREASE
FLOAT MODE
(SOLID): VOLTAGE IS CONSTANT, AND CURRENT IS MINIMAL
LITHIUM FLOAT MODE
(OFF): LITHIUM STOP CHARGE
NOTE: FLOAT VOLTAGE ONLY FOR BATCH STARTING WITH SERIAL#s 1516 IS 0.5V LOWER THAN TABLE FIGURES
Rated output power 20A at 13.8VDC
