In a typical application the WS500 is attached to a dedicated alternator supplying power to the house battery; the 2 nd battery being the chassis battery. Here the DC-DC converter may be configured to either assist in the charging of the house battery using excess power from the Chassis Alternator, or transfer power from the house battery/alternator to the chassis battery – either to augment the existing chassis alternator during high current demands, or fully emulating a 12v alternator serving the needs of the chassis battery with power supplied by the house alternator. An example of this would be to replace the OEM alternator with a 48v alternator directed to the House battery, the DC-DC converter may be configured in 2 nd Battery Augment mode to emulate the removed 12v alternator and provide power to the chassis system and starter battery. Another option would be to leave the OEM 12v alternator in place untouched, configure the DC-DC converter in Charge Assist mode allowing for the charging of a 48v house battery without the addition of a 48v alternator. Even though the WS500 is not controlling a 48v physical alternator, it is still managing the charge cycle to the 48v battery, including the complete CPE profiles as well as any CAN based BMS integration.
Default = 0 (Off/Disabled)
Volts: <FLOATING POINT NUMBER ( 0.0 33.0** )> This value is used both when transferring energy to the 2 nd battery, as well as while moving energy from the 2 nd battery. If the DC-DC converter is configured in 2 nd Battery Assist mode, the DC-DC converter will deliver this fixed voltage. A typical value is 13.8v to allow charging of the Starter battery. While in Dynamic Mode, if the 2 nd battery voltage drops below this threshold value, the DC-DC converter will begin transferring energy from the House battery to the 2 nd battery. And finally, while in Charge Assist mode, if the 2 nd battery falls below this value, energy transfer will be stopped. If set = 0.0 (default), the DC-DC converter will not provide energy to the 2 nd battery if so configured, and will provide the max DC-DC converter energy to the primary battery. Use 0.0 with care.
Volts_HalfPower: <FLOATING POINT NUMBER ( 0.0 33.0** )> Optional target voltage which is selected if the regulator is running in Half-Power mode. (See $SCA command on page 41 and $SCT command on page 48). Typically this is used in conjunction with some indication the engine is not running to have the DC-DC converter operate with a lower 2 nd battery voltage.
Set = 0.0 (default) will cause the DC-DC converter to be fully disabled in Half-power mode.
