supply unit
ARCHITECT’S
SPECIFICATIONS
The device shall be a dual well charging
base unit for use in charging compatible
rechargeable Nickel-Metal Hydride (NiMH)
batteries, including the Sennheiser model
BA 2015; either by being directly inserted
in the charging base or while the rechargeable battery is installed in a compatible
bodypack transmitter or receiver case. The
charging base unit shall provide a self-monitoring circuit to recognize when a reachable
battery is fully charged and shall automatically switch to a trickle charge mode
to prevent battery damage and increase
battery life expectancy. Temperature and
voltage monitoring shall also be provided
to decrease potential for battery damage.
Automatic battery fault detection shall
be provided. Compatible transmitters and
receivers containing rechargeable batteries
shall be automatically switched off when
inserted into the charging base.
The L 2015 quick-charging unit automatically recharges two Sennheiser BA
2015 batteries. The batteries are either inserted directly into the charger or remain in their bodypack transmitters/receivers of the System 2015, the evolution
wireless G3 100, 300 and 500 Series, Tourguide SK 2020-D and EK 1038.
