Temperature Compensation
➢
Remote Temperature Sensor available.
Battery/HCAP charging voltage is temperature compensated (temp-comp) when the remote temperature probe
is connected to the remote temperature sensor (RTS) terminal with the correct polarity.
Temperature Compensation Coefficient (25°C Reference Temp.) & Compensation Range:
•
Lead Acid: -3mV/cell/°C, from 0°C to +50°C
•
HCAP: -6mV/°C in 12V mode & -12mV/°C in 24V mode, from -25°C to +70°C
•
NiCad: Not available.
Protection
➢
Temperature Compensation
With temperature compensation, the output voltage is adjusted according to the temperature to prolong
the life of the battery or HCAP. The charger also detects an open or shorted external probe. When the
temperature probe is not connected or defective, temperature compensation is disabled.
➢
High DC Protection
If 24V DC battery is connected to the charger when 12V mode is selected, it will shut down in High DC
protection. No damage will occur to the charger.
➢
Output Short Circuit Protection
Short circuit protection is triggered when the battery voltage drops below 6V in 12V mode, or 12V in 24V
mode. The output of the charger is then turned off to protect the circuitry. The charger output will self-
recover in 2 minutes in a soft start mode to charge the battery.
➢
Output Current/Overload Protection
When demand exceeds 100% of rated DC output current, the charger limits the current and reduces the
output DC voltage to protect the charger.
➢
Thermal Protection
Charger is protected from over-temperature. The charger will derate by 30% due to over-temperature
when ≥
70°C (internal). For extreme overtemperature situations, thermal shutdown
is activated when ≥
85°C (internal). In both cases, as the temperature returns to 60°C (internal), the full output capability is
automatically restored. (Note: Thermal protection does not activate when the charger is operating at full
output current & operating in a 50°C ambient.)
