Power source:
The primary source of power is the batteries. The best performance of the unit is
when the batteries are being used to supply power without any external power.
External DC input cable wiring: Red +, Blk -.
The battery terminals and the external DC input are reverse polarity protected.
Use only matched charged state
batteries, i.e. don’t fit two batteries that are not
charged to the same capacity/level.
The batteries must be capable of charging at a rate of 220mA. Most are, but please
check.
The batteries are charged in-place using the DC socket on the top. The PDVS2mini
must be powered up for charging to take place. This is so the PDVS2mini can
actively monitor the charging process.
The batteries won’t charge with the
PDVS2mini turned off.
The unit can be used whilst being powered from the ext. DC socket but with the
following important restrictions/notes:
Minimum DC supply (to charge the batteries):
= 18Vdc
Minimum DC supply (no batteries fitted):
= 18Vdc
Maximum DC supply:
= 24Vdc
Absolute Minimum DC supply:
= 14Vdc
(unit won’t charge but will run)
Absolute Maximum DC supply:
= 24Vdc
