Whisper Power Supreme WP-BC 12/100-3 User Manual page 9

AC Source:
The charger accepts full universal input voltage (90-265Vac, 47-63Hz).
Branch Breaker:
For use on 120V AC Input source, use a 15A branch breaker to connect between the AC Source and
the charger AC Input hardwire cable (Hot – black wire, Neutral – white wire, Ground – green wire).
For use on 230V AC Input source, a minimum of 8A branch breaker is required from the AC
Input Source.
Battery Bank 1, 2 & 3 Setting:
There are two sets of main settings required on the charger for battery charging:
1) Battery Bank 1, Bank 2&3 Setting - for GEL, AGM, Flooded and Program battery:
• Battery type (GEL, AGM, Flooded, Program)
• Maximum charging current ('h-current' in A)
• Absorption to float stage current ('L-current' in A)
• Number of charging stages (Mode 2 – Bulk and Absorption stage only, Mode 3 – Bulk,
Absorption, and Float stage)
• Battery temperature (Low- 'Lo', Normal – 'nor', High – 'hi')
2) Battery Bank 1, Bank 2&3 Setting for Lithium battery type:
• Battery type (Lithium)
• Maximum charging current ('h-current' in A)
• Charge voltage (13.9 - 14.8V for 12V model and 27.8 - 29.6V for 24V model)
• Charge termination current ('L-current' in A)
Remote Port:
The Remote Display Port is used for connecting an optional external Remote Display (sold
separately) with identical functions to the built-in unit Digital Display.
BTS Port (Battery Temperature Sensor Port):
The Battery Temperature Sensor BTS (sold separately) is available and is used to connect to the
negative terminals of Battery Bank 1. When using on GEL, AGM, or Flooded battery, it measures
the battery temperature and will make small adjustments to the battery charging voltage for better
battery charging performance. When using on Lithium battery, it will not make any adjustment
to the battery charging voltage but it is used to terminate the battery charging process when
the battery temperature drops to below 0 C or higher than 60C and the charging process will
resume when it senses the battery temperature return to the normal operation temperature range.
As Battery Bank 1 is designed for charging the main battery bank on the system, it is highly
recommended to have the battery temperature sensor connected to Battery Bank 1. No setting is
required for the temperature sensor; it is recognized automatically when it is plugged into the unit.
• If the temperature sensor is not used, you can also manually set the temperature to Low
– 'Lo', Normal – 'nor', or High – 'hi' to reflect the environmental temperature for a better
charging effect. Manufacturing default setting is set to 'Normal' temperature. See more
details on Understanding the Battery Temperature in Section 5.
CAUTION: RISK OF BATTERY DAMAGE. If the temperature sensor is not being used,
never set the battery temperature lower than the actual temperature. This may overcharge
and damage the battery.
• A WhisperPower Temperature Sensor (sold separately) is available and is used to attach to
one of the batteries. It measures the battery temperature and will make small adjustments
to the battery charging voltage for better battery charging performance. As Bank 1 is
designed for charging the main battery bank on the system, it is highly recommended to
have the battery temperature sensor attached to Bank 1 battery bank.
