OPERATOR INSTRUCTIONS
A. ADVANCED DESIGN FEATURES
Battery Friendly:
•
Float and boost voltage selectable at install per specific battery vendor recommendations.
•
Remote temperature compensation for most accurate float and boost voltage control.
•
Able to charge a dead battery.
•
Float and Boost voltage electronically controlled with a 4-rate fast charge program. See chart below.
Temperature Compensation:
•
The battery charger is temperature compensated to match the negative temperature coefficient of the bat-
tery. Thus, the output voltage will increase slightly as the temperature decreases and decrease as tempera-
ture increases.
•
The output voltage is clamped at 0 and +40 Degrees C to protect against extremely high or low output
voltage. See chart below.
Fault Tolerant:
The charger is protected from the following faults:
•
Internal power component failures.
•
Over heating (over temperature output power reduction).
•
Protected against power line transients and surges
