| Battery
Charging: |
By
charging Lead Acid Batteries, adjust unit to shown charge voltage with no load connected.
This will keep your Battery charged to 90 - 96% under normal temp. conditions, 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. |

|
| 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 optain 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: Looking at Fig. 4, a typical Current Limit is shown together with
Toggle Mode point.
This point is at 40 - 60 % of rated Output Voltage on all
units.
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 internal power losses.
