POWER SOURCE & CHARGING
3.1.
Battery
The battery is a nominal 12 Volt sealed lead acid (SLA) battery pack. The lighting unit may be
operated in any orientation except directly upside down. Even in this mode it may be operated for
very short periods but the unit must not be charged in this orientation as the “venting” holes may
become blocked. This will prevent venting if for some reason the unit is being overcharged.
Safety Note: Do not charge the unit directly upside down with the unit resting on its head as the
“venting” holes may become blocked which may irrepairably damage the battery.
3.2.
Power Supply Unit (PSU)
The unit may be NOT be operated under external mains power – this is prevented within software.
This is different from CORE POINT20 and POINT30 units which have their own built-in power supplies
and so will operate in either battery or mains powered modes.
The external power supply input range is 100-240VAC at 50/60Hz. These supplies come with
individual units or with a flight case (depending on option chosen) and may be used worldwide.
The unit will enter charging mode whenever the external power is applied (See Section 3.3).
When power is removed the unit will switch off completely. This allows a flight case to be plugged in,
units charged, then disconnected from power, safe in the knowledge all units will switch themselves
off afterwards.

Battery Charging & Discharging
CHARGING
Simply plug the mains charging base into the wall or place into a flight case on its bottom connector.
The unit manages its own charging so it may be left connected to mains permanently. However, the
battery specification provides that 95% of charge is maintained over 3 months when power is
removed.
Voltage of the battery can be seen in one of the menu options, achieving full charge at
approximately 14.8V (at 20°C). This will fall approximately to 13.8V once the charger has been
removed. The charging current can also be monitored (see DIAGnostics menu ‘AN1’) and should be
around 2.5 Amps on full-charge, falling when the battery is near capacity. The charging LED on the
keypad (lower right) and LEDs in the head will flash amber whilst initial charging takes place up to
around 60% capacity and a “^” symbol will appear in the BATT menu option. Between 60 & 95%
capacity the display will turn to solid amber. When the battery is full the charging LED will turn
