Function description of the separate battery power supply

The ASR Battery Power is housed in massive separate case. The case contains six batteries,
each 6Volts/12Ampere-hours and capacitors for buffering summing up to 440,000µF.
All operations are controlled by an optical digital logic circuitry to avoid RF distortions.

Function explanation and description of the control Leds
• turned Off (Off-mode): the batteries are charged with 20Volt. The yellow "Charge" Led
is shining. When full (19,5Volt) the green Leds "Batt+Full" and "Batt-Full" are shining.
• turned On (Line-mode): the batteries are charged with 20V. The main unit is supplied
with +/- 12 Volts out of the charging circuit to preheat the built in circuits.
The red "Standby" and
• turned on (Batt-mode): The yellow led
Then the batteries are switched to the buffering capacitors with 2 Power Mos-Fets.
The main unit is supplied with current out of the batteries.
• Then the charging transformer is separated via relay in both phases from the AC power line.
The green Led "Batt
• during „Batt"-mode the voltage at the batteries is constantly monitored. When the voltage is
lower than 17 Volts the batteries are empty, and the
switches into the charging mode and the main unit is supplied out of the charging circuitry.
• Also during charging the main unit is working and you can still listen to music.
• when the batteries are fully charged the voltage reaches 19,5 Volts and the green Leds
"Batt+Full" and "Batt-Full" are shining. Then the charging transformer is disconnected,
and the ASR Basis Exclusive is supplied again out of the batteries.
• fully charged, the batteries can supply the ASR Basis Exclusive for approximately 60 hours.
To lengthen the lifetime of the batteries please turn the main unit to the „Line" position after
approximately 24 hours of playing in "Batt" position, or just over night. In this case the batteries
are not much discharged. Lower quantity of discharging is good for the battery life expectancy.
One hour of charging is equivalent to about three hours of playing music.
Fuses: 0,5 Amp slow-blow for 230V, 1 Amp for 115V for the charging transformer.
This fuse is located in a small drawer in the power input module for the AC cord.
2 Fuses 8A slow-blow protect the batteries. This fuses are located at the PCB board.
