| Battery Charging: |
By
charging Lead Acid Batteries, just mount the BTS (Battery Temp. Sensor) to
the terminals, and unit will automatically jump to the desired voltage, and
adjust this by 3,3mV/°C/cell.
This will keep your Battery charged to 93 - 96% in the range -25 to +55°C in normal
standby operation.Or contact your local Battery Supplier,
for technical information around Charge Voltage in Standby Operation and readjust unit to
desired voltage, with no Load and typical at 25°C. |

|
|
This relay set will
be closed when unit is in regulation. When No input or in current limit this
relay will be open. Contact set is potential free and can be connected as an
alarm for no or not correct output.
Example:
If a discharged battery draw Output Voltage down, Contact Set remain open
untill Battery Voltage is up. |
| |
|
|
|
|
| Parallel Operation: |
|
|
|
|
When
connecting in parallel, use the same wire diameter/length from unit to common tie point,
to best parallel performance.
Units are factory adjusted, to
above voltages, to obtain best performance in parallel operation, - - if this adjustment
is changed, readjust unit's to wanted Output voltage (+/- 10mV) with no Load for each
unit, before connecting in parallel. |
|
Current Limit:
When unit reaches 40% to 50% Output
Voltage in Current Limit, unit will reach its Toggle Mode point.
When unit reaches its Toggle Mode point, unit will stop, and with its
automatically restart within seconds, unit will in this mode stand a constant short with no
damage or increased internal power losses. |
