Power Supply - Televes H30 Series Instruction Manual

Power supply

A DC adapter is provided to power and charge the
meter. Plug the adapter into a properly grounded
electrical supply and the power connector on the
side of the unit.
When external power is supplied, the battery
management system automatically controls the
charging process.
A battery icon indicates the charge status of the
battery.
When the battery is fully charged, the battery icon
is completely filled. As the battery discharges, the
amount the icon is filled decreases in steps.
The icon shows 5 states representing the
approximate battery charge:
- Battery charge less than 5%.
- Battery charge between 5% and 25%.
- Battery charge between 25% and 50%.
- Battery charge between 50% and 75%.
- Battery charge greater than 75%.
From a fully discharged state, a full charge takes
approximately 8 hours and a 3 hour charge will
provide approximately a 75% charge.
The charge management system will detect
various conditions preventing charging, such as a
battery that is over a safe temperature.
Battery Recommendations
To maximize battery life:
Avoid fully discharging the battery.
The battery should always be charged with the
battery pack attached to the device and using
the supplied DC adapter or applying a constant
voltage within the specified range (12-15VDC).
For long term storage, keep the unit at room
temperature, or about 25º C. Start with a charged
battery and re-charge the battery every 2 to 3
months.
