2.1.4 Power supply
* from the power line, monitor design in IEC protection class I
Potential equalization
* potential equalization connection according to DIN 42 801(measurement in or at the
heart) or connection for function ground (interference elimination during general cardio-
logical examinations)
Rated voltage range from 95 to 240 V AC
* operating voltage range from 85 to 264 V, 49 to 65 Hz
* rated current from 0.15 to 0.3 A
Internal power supply (rechargeable battery)
* automatic toggling from line to battery operation and vice versa
* integrated charge circuit with automatic adaption of charge characteristics
* fast battery charging to 80% of its capacity within 3.5 hours, afterwards
* normal charging to 100% of its capacity within 8 hours, afterwards
* continuous trickle charging by means of charge pulses to prevent the “memory effect”
Charge balance
— measurement of the charge and load current
— compensation for battery self-discharge
— graphic indication of battery capacity
Alarms
— warning when battery provides power for only 5 minutes of operation (without
recorder)
— automatic switch-off at 10.0 V to prevent overdischarging
Capacity of the rechargeable battery
— 2000 mAh, 12 volts
Charging indicator
— LED
Operating time
— approx. 3 hours (typical operating time with fully charged battery at 23 °C, at a
battery temperature of 60 °C the capacity may be reduced to 70%)
(min. 2 hours at 25 °C ambient temperature and new, fully charged battery)
